So, as some of you that read my coralline algae thread know, I recently bought a used 210 gallon tank. I am getting ready to get the filtration setup for the tank now, but am a total noob on using sump/overflow style filtration. I have always been a canister filter and/or HOB guy.

The tank is an older model Aqueon, with dual megaflow overflows.
I was given the plumbing for each overflow as well. I need new bulkheads for each connection, since the previous owner had glued, then cut and damaged the threads on the olds. From what I understand, I am to use (1) 1" and (1) 3/4" bulkhead behind each overflow. 1" is for drain, 3/4" is for return.
My first question, is that sufficient? Should I modify it? I went ahead and ordered my bulkheads cause I was hoping to make some really good progress this upcoming weekend, but I can always change the order.

Second, my plan is to use my current 55gallon as the sump. In order to accomplish this, I figure I can go ahead and get my bulkheads in place, run a small bit of tubing off the bottom of my drain and return lines and throw me a ball valve there. This would allow me to fill the tank, move my fish over, and move my current filters over so that I could work on changing the 55gallon over to a sump.

This is where I am at a loss, I can't decide what type of sump would be best. Do I go wet/dry trickle, do I go refugium/sump mix, etc. To aid in helping with this, below is the current list of fish that will be going in it.
Also, I read somewhere I can expect about 350GPH drain from each line, is that correct?
What return pumps would you guys recommend? What type of GPH should I be shooting for?

Stock and current sizes
(1) 3" JD
(1) 3" Oscar
(1) 3" Texas Cichlid
(2) 4.5" Geo Altifrons

Stock that will be added later:
(1) Green Terror
(4) Geo Altifrons
???

I don't really think I need any bottom feeders, as currently my geos do a pretty good job of picking up any leftovers (as expected). I assume that will only get better once I have more of them.

I would like some midwater dithers, I have had silver dollars before and liked them, but I am not sold on them. Any ideas?
 
Really, all sumps have their advantages and disadvantages. You mentioned either a refugium style sump or a wet/dry setup.

With a refugium you will be able to keep plants in it like the pothos that will help lower nitrates and you will be able to keep other small critters or breed feeders in it. Also, you can use many different types of media, and get some cheaper options, like lava rock, if you are on a budget. This is the style I plan on using for my 55 gallon sump.

The real main advantage of a wet/dry sump is the surface area of water to air running through the bio balls. This allows for a really good gas exchange and helps keep the water well oxygenated. However, to my knowledge, you pretty much have to run bio balls with this setup and they are expensive. It also doesn't add much additional water volume, like the refugium style sump does.

As for the flow rate, you will need to calculate the total system gallons (210+55=265 gallons) and determine a turnover rate. Now, you won't have exactly 265 gallons because a 210 doesn't hold quite 210 gallons and your sump will not be completely full. I would round down to 240 or 250 gallons when determining your turnover rate.

So, let's say you want a 5x turnover rate. You need to multiply the 250 gallons by 5 and get 1,250gph. This means you need to find a pump that can pump this 1,250gph, after you factor in head loss. I would say most setups will experience a head loss of 4-6ft. Use this and look at the pumps you want to get to determine which will flow enough for your needs. I also recommend 2 smaller pumps instead of one large one so that you have some redundancy, in case one fails.

Now, you will definitely need to make sure your overflows will handle that volume, but in your case I think you have some options that will work fine. I would use the 1" as your main overflow and then set up the 3/4" as an emergency overflow that sits a little bit higher than the 1". Then, your pump return(s) can just be a hang on back style.

I hope this helps. Keep us posted on your progress. It's nice to see that others can make progress, since I can't seem to find the time to. Lol
 
I dont know much about sumps/overflows as i just recently got into them. The members in this section are great man just ask questions

I dont know if i would use the 1 inch as the main drain and the 3/4 as the E drain.

From the way i understand it you want that e drain to be able to take on all of the flow that your main drain does.

Wait for more experienced members to hime in but i think i would be thinking about using the 3/4 as my main drain (full siphon) adjusted with a gate valve then use the 1 inch drain as the Edrain. Size the pump to the gph of the e drains

Look up the herbie method and definitly wait for others to chime in

I saw the herbie method, it would require me to replumb what came with it. I kind of like what did come with it though. Here is the plumbing I have for it:

Oh i dont know why i thought you were trying to use both as drains sorry
 
millerkid519 millerkid519 should he base his pimp gph off the 1 inch drain ?
