Dual sumps?

[Trickdout69]

This may be a stupid question and I'm very new to this but I bought a 210 with dual megaflow overflows. My question is do both over flows have to be balanced? The reason im asking is I have a 10g sump with refugium on my small set up and I also have a 30g sump with fuge can I pipe one overflow to the 30g and the other to the 10g. Obviously the 10g would not have as much flow if this is a bad idea please let me know. Thank you

Yeah, won't work.

Sorry for the short response, it's kind of hard to explain why other than it will most likely cause a flood.

Ok if it's not right I defiantly don't want to do it. Is there any way I can use the two together? Or will the 30g be enough? I plan on running it with a refugium and a 2900gph pump

 

[Otter_rs]

Are the sumps acrylic or glass? That pump seems kinda big for that setup.

Can work. What you need to do is have one overflow go to the 30. The second overflow you can put a T on with one side going to the 30 and the other side with either a ball of gate valve to restrict it to the 10 gallon.

In order for this to work, the 10 will have to sit higher than the 30 gallon and gravity feed via bulkheads back into the 30.

Agreed, but that would still make all flow go through the 30, which is not what he asked.

In the event of a power outage, put on waders lol

In all seriousness though, you would be alot better off with 1 bigger sump/fuge on that size system. It is doable, but doesn't leave for alot of overflow protection and odds of a flood will be high to provide enough water in those small fuges to run that size pump. If you feel you must use the ones you already have, I would plumb them together and have both drains empty into one tank and flow into the return chamber in the 2nd tank...... But I would still just go with one bigger 75g+ sump for that size tank, and more water volume doesn't ever hurt

They are glass. And the tank is a 210gallon I just want the the best set up I can do with this stuff

+1 that's why I asked if his sumps were both acrylic. But I agree, if its an option, just go bigger. So much easier and safer.

If they are glass, there isn't a lot of options that give you a great result. Sorry. If you have the money, just get the biggest sump you can fit into the system.

I wanted to do a 55 gallon that I have but the stand the tank came with is only 24" tall and the 55 is 21" tall it would fit just barley but would give me no room to get to it or a skimmer

 

[Otter_rs]

Yeah, that wouldn't work out well either.

+1. 40 long will work out or a 40 breeder. Its 36x18x17.

 

[Trickdout69]

I have a 30 long will that work

Sure as long as you make plumb it and use the right stuff to keep as little drain back as possible when you shut the pump off. The last thing you want is water on the floor every time you shut the pump off

One more option, if you drill or have the two sumps drilled on the side or end you can join them with flexible tubing. Then one could be the main sump and the other could be the refugium portion of the sump. I'd make the ten be the refugium portion. You would want to have some of the exhaust from the skimmer tee off with a ball valve into sock for a bubble trap at the far end of the 10 to provide circulation. Both overflows from the main display tank would need to dump into the 30. Be sure to allow plenty of flex in the connecting tube between the tanks so you don't stress and break the thin glass of these tanks. I don't like a lot of circulation through a refugium tank so this IMO is a perfect solution. It will work fine.

A 24" stand for a 210... you can't even put a respectable skimmer for that tank in that thing IMO. Although if your planning to try to put one into either of those tanks its not going to be much for that tank anyway....

If It were me I would be looking into building a new stand and getting a bigger sump. You will thank me later lol

Very true. Most skimmers rated for a tank that size are 24" and taller.
