Yes, you read that right. I didn't add an extra zero by accident. AND it's technically 1196 gallons. AND I have never EVER looked after fish before. I am currently in the information-gathering phase. I don't foresee really getting starting on anything for a few more months but I figure planning earlier and longer is better. I have been reading and researching for weeks already trying to educate myself and now that I know a little more would like some input and opinions. So here it goes...

I am lucky owner of a 1000 gallon in-wall aquarium through the purchase of its house. I have pictures available to post and will do so when I reach the post limit required.

It measures 8 feet long x 4 feet deep x 5 feet high and is accessible through an aquarium maintenance room behind it. Unfortunately space is pretty tight in there.


The previous owner kept local river fish and from my understanding only a handful. He ran a chiller to keep the tank the appropriate temperature.


There is a relatively small sump for the tank size located to the side of the aquarium and below the chiller. It is approximately 50 gallons. Two 2 inch pipes feed into it with one 1.5 inch pipe attached to a 3600 gph pump. It appears to have been a submerged media sump filter though all filter media has since been removed.


My plan is to slowly work on this and get comfortable with taking care of the tank before ever adding fish. In the end, I want to have a cichlid tank consisting of haps/peacocks including frontosas. This will be a planted tank as well. After getting the tank set up appropriately I would be cycling it and planting it. Once it was decently grown out I would plan to add my fish.

My main questions are regarding the sump tank at the moment. It seems significantly undersized for the size of tank especially considering the fact that I will be filling it with a number of cichlids. I have read a lot about sump sizes and filtration for cichlids (overfiltering). There's not much information regarding tanks of this size however. I would love to get some opinions on how big a sump tank, amount of biomedia, and amount of filtration needed for a tank of this size. I will be adding in powerheads to the tank to increase turnover but the whole 10x the size of the tank filtration would put me at needing 10000 gph through the sump which would certainly be limited by the size of the outflow pipe and require the addition of more outflow pipes.

The real issue I run into with sump tank sizes is required space. I have about 26.5" x 25.5" of room to the side where the current sump lies. I have looked at adding the sump tank below the main tank but the supporting beams would prevent placing anything of significant size under it. I would love to just build something like a 250 gallon sump but I'm limited to that available space to the side of the aquarium.

In this available space how high can you go?
You may want to consider using plastic barrels to make your filter.
Is there any other space? Could the plumbing be ran to any other location? Another room perhaps?

I can potentially go all the way up to where the chiller sits above it which is 5 feet above ground. I wonder if there would be an issue with the weight of the water column if it went that high. I would probably have to make a plywood tank due to the unique size. Additionally, a tall sump would be more challenging to maintain. I have also looked at 55 gallon drums like you mentioned.
 
I have looked at the 55 gallon drums option before and seen some youtube videos on them. I think I could fit more volume into a plywood tank in that area than two drums side by side though. But how much volume is needed?
 
There was a chart floating around here on MFK that compared the difference between bio media and how much is needed. I will see if I can find it.

If anyone reads this and knows what I'm talking about please post it up Thanks
 
If there isn't another room to run the filtration (like BIG-G had mentioned), I would consider running 2x Ultima II 1000's .. that will take care of the mechanical part as well as help with the bio part. Add additional moving media with some prefilters and you should be golden.
 
Uploading the pictures now.

Front view. The aquarium measures 8'L x 4'D x 5'H.

The aquarium is accessible through a separate maintenance room behind it but space is tight.

There are two access panels into the aquarium. A chiller is located to the side of the aquarium.

BIG-G BIG-G is this the chart you were talking about?

I've had a look through the chart but still not sure which would be the best to go with for my situation.

vincentwugwg vincentwugwg I took a look at the Ultima II 1000's. While they look great they will be too costly for one much less 2 of those guys.
 
If i bought an house and it came with a tank like that the last thing i'd be thinking about at this stage is how i'd be running it and what fish i'd be putting in it etc etc. That is a huge amount of weight when full and the depth of it would scare me to death regarding pressure. Before i did anything i'd want to know absolutely every detail from the previous owner of how it came to be there. I'd be checking everything for absolute peace of mind, especially if it was a self build. The first three areas i'd look at are,
1. The structure it is sat on.
2. Thickness of glass/acrylic.
3. The seams.

Just because the previous owner had this tank set up and running with no problems would mean diddly squat with me, (or maybe they did have problems, this is even more reason to get them over and quiz them). Once you have complete peace of mind that the whole tank/base structure is sound then you can move on to how you're going to run it. You say you're new to the hobby, well you've come to right forum, the guys on here will help guide you over the coming months. Good luck.
 
I am confident in its construction. This home was custom built with the aquarium custom made and installed during the home building process. The aquarium is 12 years old and currently filled with water. There are no leaks.

The man who laid the concrete for the basement foundation it sits on goes to my church. When I purchased the house he told me how much of a pain it was laying the foundation for the aquarium room. It was clearly prepared for before being custom installed (not self-made). I have not measured the thickness of the thickness of the tank but will and will post. Thanks!

I agree, you have definitely come to the right place to get this up and running.

It's definitely good advice to check out the structural integrity of the tank and stand. That tank will weigh approximately 10,000lbs when full of water, which is not something to take lightly. It would probably be best to try to find an experienced aquarium builder in your area to come and check out the tank for you. Also, it would be beneficial for you to post some good clear pictures of the seams here on MFK so that some of the more experienced hobbyists can take a look. Whether it's glass or acrylic, which you haven't mentioned yet, there are plenty of people on here that can evaluate the pictures and give you a good idea of the condition of the seams. This is, of course, no guarantee.

For filtration, I see two main options. First, you could save up for the Ultima II's. These are really the best way to filter a tank of this size. The backwash feature makes cleaning and water changes very easy and quick. In my opinion, it would be worth it to wait a few more months to have the funds for these filters.

Second filtration option is a sump. Obviously, you have already discovered that the current Rubbermaid tub sump is far too small. It looks as if the small walls that sit around it can be removed to give a larger space. Still, I think your best sump option would be to find a used 220-265gal tank and put it in the small filtration room that sits behind the tank. This size tank is only 2ft wide so it will be tight in there, but should be manageable. Then, run your plumbing to that tank.

You might want to see about having additional bulkheads installed so that you can increase filtration flow. You really want your flow to be somewhere around 5-6000gph after head loss, not including internal power heads.

Another item to consider is heating the tank. A tank this size will require a lot of wattage for heating. Since the previous owner used this for cold water fish, there is no method of heating. The chiller is useless to you, so I would recommend trying to sell it. Even if you want to keep cold water fish, it's really not a necessary piece of equipment for an indoor tank. If it were me, I'd put a few largemouth bass in there and setup a cold water drip system.

That brings me to my next topic, a drip system. I see that there are water lines in the filtration room. I would highly recommend you look into a drip system so that you can avoid needing to do water changes often, if at all. If you end up changing your mind about warm water versus cold water fish, you can just hook up the cold water line to a carbon filter and run it into the tank. Otherwise, you will have to get a valve that will keep an accurate mix of cold and hot water for a tropical tank.

For plants, I would check that the cichlids won't tear them up. It seems to me that the cichlids will end up destroying the plants in the tank.

I really think you should take a step back and take this process slow. Honestly, to do this right, I think you are looking at several thousand dollars to get the proper equipment purchased, setup and running. In addition, a tank this size, especially if it's a heated tropical tank, will definitely have a significant impact on your electric bill. So keep that in mind as you plan out your budget and as you decide what equipment to buy. You want to make sure you get energy efficient equipment to keep the running costs as low as possible.

Good luck and keep us posted on your progress! Sure is an exciting endeavor you have ahead of you and I'm sure you will find it very rewarding.
