Hello,

I was recommended to start a thread so here goes!

I recently found a broken 220 gallon aquarium. I plan to separate the pieces and make a large "L" corner aquarium with the glass that is usable. I've been looking at builds and have an idea of what these need to look like to not leak. I enjoyed watching the video of the tank that is still running. I've built some of my own stuff including plumbing, a sump, a hood, and a stand. I feel I am capable of most of the ideas here and would like to employ them.

End goal:

My wife likes saltwater tanks that are very colorful. The theme behind this tank will be maximum color and vibrancy. We are not particular on fish or coral choice other than color. I do plan to have here make some selections of fish and begin working on an ideal biotope. The footprint will be 36-38 square feet and I feel the possibilities will be in decent variety. My one contribution to stocking preference would be a cow fish.

Projected ideal build:

The tank: This aquarium will be tall enough to see over the back of the sofa so a sofa could sit in front of it ( I have an idea for sofa movement; no fish ignorance here) and the materials will be the two main viewing glass panes on the inside corner of the tank, the two side panes on the end caps, and plywood framing the glass as well as walling in the back as well as floor of the aquarium. If I get lucky, (haven't seen the crack to know the pattern or severity) I'll use the bottom pane as a viewing panel at a 45 degree angle between the main panes to provide less blind spot and larger area for coral growth. I would use plywood for bracing as well and would like to acrylic finish these pieces. If need be, I would pond armor the braces as well as sides and inside bottom. I plan to follow Uaru Joey's build video for his 375 gal build as it has a finished look and purpose I am aimed at producing. I am somewhat concerned about light penetration and would like to consider braces that are vertical rather than horizontal to allow for more light penetration. I believe this would be beneficial for the coral. Likewise, I am unopposed to using lead pipes with pond armor coating to again allow better light coverage. I think this would be possible with some kind of plate to provide the necessary surface area to brace the wood from bowing.

The stand: I think enough would could support it.... I think maybe for this build (500-600 gallons), I would be better served with some 2x4s for cushion and distribution directly under the tank bottom and then some cinder blocks. I would skirt this with a cabinet finish since this will be in the living room. The finish would likely be a gloss black upwards of acrylic. Every time I bring home an aquarium to restore, she paints it black.

The canopy: If I can get by with it, I'll build my own LED lights and suspend them from the ceiling or something I attach to the rim of the aquarium. She may or may not be interested in the whole separated box. I could see how it could be useful as a moisture collector and I would vent to the carport. A 38 square foot water footprint has to evaporate a sizable amount of water into the air. I can't see it any other way. For the lids, I have glass on other aquariums I could make work for this project.

The filtration: Because this is plywood, I feel this will be very easy to plumb. I plan to use two or three sumps. I have a 125 gallon aquarium that just needs a brace and a 55 gallon aquarium in the same condition. I have a 45 gallon that needs a pane and I have it. I'm just lazy and try not to blow a whole tube of silicone on one job. I usually repair 5 or more tanks at a time to get the most bang for my buck on scrap money. Yes, I fund my hobby with people's broken tanks. It works! I'd like to use three or four overflows to send water down and hold a steady water level. I haven't wrapped my head around how to keep the overflows functioning during a water change and keep my pumps from burning up from the absence of water. I have a 375 gallon tote I bought for preparing water. I'm not worried about hours of buckets. It has a 2 1/2" flood gate so I imagine I could get water in at least as fast as I could get it out if I keep the volume of water the same or less as it leaves compared to what comes in. I have no idea if saltwater fish or coral like to have water move a certain direction or what. I thought I would use a variety of spray nozzles to reintroduce water into the tank on the return side of the sump. Top/Middle/Bottom/Rear/Front as long as I can hide it behind coral or plywood. I just don't like to see wires or other non-organic structures inside the water column. As far as dead spots and water circulation, I wanted to do wave controllers. How many? I don't know. How many nozzles where and what gph? I don't know. Feel free to offer suggestions. This build will start once our finances calm down from moving into the house we just bought and will be built piece by piece.

Cycling: I like mountain bikes. I have done freshwater till now. I usually take tank water from another tank and put that in with water and run the filtration. The largest I've ever cycled was 125 gallons. I don't have a clue how best to do saltwater. I do know that we won't populate this thing fully and immediately. We'll likely start with a couple of coral choices and some clowns. That seems to be the starter pack I've seen over the years. I don't think this tank will have full occupation till a year after cycling. No worries about bio-load shock here! Anyone have suggestions on cycling tips? Are algae scrubbers a good idea or is that counter intuitive like a tank with plants?
 
Salt is a whole different game from fresh. I've done salt for years up til about 5 years ago. For any salt system to work you need a few really good pieces of equipment especially if you're talking coral. Skimmer is the most important piece do not skimp here oversize it!, followed by turn over huge return pump or multiple pumps going with plywood you can put holes anywhere so that's good, then obviously light full spectrum high intensity dimmable.
Cycling. I used to mountain bike, now I'm lazy and fat. It's a reef so live rock is going to be needed. Or dead rock and a few pieces of live rock that will get you cycling.
Fish coral choices. Clowns are jerks! Don't add them first they will harass and possibly kill any new comer. Focus on your coral choices now certain ones can not be near each other as they will war. Soft corals release toxins in the water to kill other corals that may take their space, carbon is needed in your filter. Lps have stinging tenticles that can be as long as 12" or more that burn and kill other corals, watch spacing and flow direction. Sps the colored sticks, can be difficult to grow needs high calcium and alk dosing encrusts rocks and neighboring corals.
Cow fish......I think they may eat certain corals not sure never had one.
Flow, random wave generator is a great idea.
Hope some of that helps! Great start to the thread btw.

It does!

I've seen sumps with the skimmer built into the intake. The water pretty much crashes down onto a media and makes bubbles that are allowed to spill over to be removed. This is something I was planning on doing with all of the sumps I include.

I figured live rock was a necessity. When do I add it in the cycle process? What is a clear sign that water has cycled in the tank before I add anything? Should I be adding water and live rock from the get go?

I don't know much about cowfish except how they look. It isn't a necessity in any capacity. Thank you for the info on clowns! I don't know anything about saltwater fish. I have only kept freshwater.

What are LPS or SPS? Do I need them? Are they at least colorful enough to consider?

Thanks again!
 
Ok I'm going to break this down dont' know how much info I can give at one time.
Skimmers.
I think that's a good idea but it's not going to be enough to remove the kind of gunk you will with a traditional skimmer. Look here this is what you will need.

Like I said the skimmer is the heart of your filtration DON'T SKIMP!
You'd be better off dumping into filter socks then the skimmer can pick up then through a refugium and back to the tank. Any chemical filtration can happen anywhere along the way. With a reef tank you are looking for much more pristine water conditions. Like 0 amm 0 trite and 5-10 trates alk 8-10dkh calcium 400ish. Phosphates 0-0.5 .

Live rock. Start the tank with it. Depending on how far you live from an lfs that carries salt fish and corals or if you have to order online the live rock will have some degree of die off on it which will help cycle your tank. Problem with online live rock is you will have huge amounts of die off if temp or moisture lvls are not kept at a good lvl. For the most part you will know when your tank is cycled the same as fresh test 0 amm 0 trite and a trace of trates. Also with saltwater comes microscopic critters called diatoms (you can get them in fresh too) they are not bad but at the end of your cycle you will tend to get a large die off of them and they turn brown so all your sand and rock will get a tan to brown dusting. A good indication you can start adding stuff. But still test.

Lps= large polyp stoney coral
Sps= small polyp stoney coral
These are the corals that grow a reef in the wild. They have a skeleton which is why you must add calcium and keep your alk up. And yes these are some of the most saught after corals with some of the coolest colors and shapes. But also can be very difficult to make happy and keep happy. Happy coral =live growing coral.

Of all my years of salt this is one of the only remaining pics of any of my tanks this was my 75g. Technically my 2nd salt tank upgraded from a 34g cube. That was upgraded to a 120g and then a 125g was added to the "system" in the living room and tied into a massive basement salt "sump". Yeah it got way outta hand lol.

Definitely hadn't plan to skimp on the skimmer. That product looks like two skimmers in one. It's appeal is to save space. I will have 38 square feet. I could fit like 90 of those comfortably. I think we're on the same page with flow: socks > skimmer > refugium > return.

I'm not used to testing for calcium or phosphate.

Talk to me about refugiums. I have zero experience and hadn't looked into them in the past. It put off research because I had no idea when I would be capable of running a saltwater tank. Time to start...
 
Refugium is going to be near the end of the run in your sump, usually. You could run a completely seperate tank for a refugium with filtered water from the sump also. This is where you will grow macro algaes. Cheato, ulva, there's so many I can't remember or name them all. These will help remove nitrates. You could do a deep sand bed here also.

I tried many things to keep nitrates down. Probably the best item I purchased in the ultra low nitrate chase was a biopellet reactor. Took my 20ppm to 5ppm between water changes.

Go farther down the list of skimmers too that was just a recommendation on an appropriatly sized one. The one I had was over 5' tall and 24" in diameter it had a reefflo hammerhead running if I remember correctly, something around 6000 gph. It was recommended for heavily stocked salt systems up to 1500g this was probably a bit under sized for what I had going on really. I never tried to run multiple skimmers and probably should have honestly since I had about 5 just gathering dust after a few years. Do your research, go bigger then you need, and look for quality. I've wasted so much money on equipment over the years. Lol

I have a similar experience with money. I find that if I buy the top line, I usually don't have problems and spend the same as if I bought the bottom of the barrel line after a period of time. I'm aimed at your hindsight idea to go ahead and use multiple skimmers. I think it will not only move the same volume but agitate more surface area and therefore be more effective.

Deep sand bed? How do these work?
 
It allows a place for anarobic bacteria to grow and help reduce nitrate. Needs 4+ inches to be effective. Lots of arguments on if they work if they are safe if if if. I've used it didn't kill anyone. Might have helped might not have.
 
Supposedly a build up of gases in the sand if it doesn' get mixed up. I know after about it set up for 3 years when I took it down that sand stank!
