I'm designing a system for my basement, and originally I was going to have a 300 gallon ft using a SLO to a media based gb overflowing to a dwc gb overflowing to a sump and back to my ft. However, I've run into an issue where I can't fit a 300 gallon ft down into my basement. Is it possible to have 2 150 gallon tanks plumbed together and have a SLO in both of them flowing to the media based gb? Or would that even work?

Sure. Why not? Just twice the plumbing.

if you plumb them together as one tank, one SLO is all you will need.

How would I plumb them together so that I would only need one SLO? If they are just connected by pipes and only one ft has the SLO wouldn't the other get buildup of solids on the bottom?

depends what sort of tanks you are using.....

there is also the fact that both SLOs would have to be set up EXACTLY the same in every way for each to work well, pumping into one tank or both, if they are joined and you have 2 exits..... one exit will perform differently to the other....

Yeah but nah but.
If you can regulate the water in then the water out, through the slo's, is also regulated. I have been using this system for a while now to separate flings from the larger fish. 2 different sized tanks with different sized slo's.

Seems like to me - and someone correct me if I am wrong here, that you could simply pipe each tank separately, into the system - both with their own SLO. Pipe the return similarly, one return line to each tank.

Hmm I was hoping to plumb them together so I would essentially be controlling one tank as opposed to monitoring two separate ones. Maybe I'll give both methods a try! Try it separately first and if I don't like it plumb them together..

I can't see why you can't use a SLO to plumb the tanks together.

So basically have it being pumped into the first tank from the sump then SLO into the second tank then SLO into the 1st grow bed?

This guy did it. But, personally, I wouldn't do it. Why introduce solids from one fish tank, directly into another? Doesn't make sense to me.

This forum software sucks.

Actually the guy did it the correct way. When the solids exit the FT they drop down into the main drain line.

But, if he had exited the tank with a elbow laid horizontal and connected the next tank with a T also horizontal then solids from one could enter the 2 or multiple tanks.

Drains for gang sinks, toilets, showers are done this way, the drain drops into a main line.

The only way that the solids could flow into the next tank in line is if there is a clog at the end of the main drain line and you get a back up.

I wouldn't do it either. I would have one tank. But that isn't possible and Dr Abraham doesn't want to plumb the tanks separately. And the solids from tank one that get in to its SLO and then tank two, would be the same solids that would have been mixed up in a combined tank anyway... at least that's how it seems to me on a sleep deprived Olympic Sunday morning.

Sorry typo above - phone autocorrect being unhelpful! I meant DrAbrahm.
