Two sets should be good, three is better ;-) The problem is I'd be worried all the time about that small chance when both fail, I'll have a lot of clean up to do.Yes, that was the idea. Going to give it a shot and see. Figured if I block off the pipes with some sponge/mesh, shrimp can't go between, use 2 sets of pipes per tank to account for clogging, should be good.
No, each tank can have its own filter. You just put a upside down U pipe in between the 2 tanks, I took a piece of airline tubing into the U and sucked until the air was out and a siphon was started. Then any changes in the 1 tank were reflected in the 2nd tank because of gravity and the siphon. I'll get some pics once I set it up and see how it works long term, and as soon as I get around to swapping out another 10gal with the one that is shorter. Driving me nuts being a tad shorter. lol.Pictures!!! So what do you do, put filter discharge in one tank and return in another??
giving 3 10gal tanks the water volume of a 30gal for param stability, etc while putting mesh on the U pipes will prevent shrimp from crossing sides, so I can have CBS, CRS, golden in 3 tanks with the stability of 30gals.What is this accomplishing??
I'm going to do 2-3 1" pipes as I have those sitting around and the elbows for it. Not doing a sump, just want to share the water between the 3 tanks, and doing 2-3 will allow for any being clogged, although I doubt that will happen, I check all my tanks everyday for filter flow, water levels, TDS, pH, etc so I should be ok with 2, but 3 if I have the PVC and elbows here. I like the idea of having stability of the params between the 3, especially for crystals and being able to separate them.Where the heck are you guy's going to get all this bad bacteria or a killer bug from that you are worried about?
I quarantine all new stuff before it gets in my tanks and don't think I have that worry.
A contaminated food source will end up everywhere anyway so isolation solves nothing there.
Single 1" PVC will handle 265gph no problem. The 20g rack w/2 pipes is a 500gph sump pump return, I like it.
I do get your point. I can see how this would work better with a sump with drain on tank 1, return on tank 3 so the water ebb's and flows via gravity to keep all 3 tanks the same. I have a small internal Fluval filter that I can plumb a airline hose on to use like a powerhead, so I'm going to try that. Put the internal filter in tank 1, pump it to tank 3, which will cause the water level in tank 1 to drop as it pumps water out which will draw water from tank 2 to increase the volume in tank 1 and so on and should then help keep the water moving between the 3 tanks at a slow rate.I may have missed something, but without a pump moving water between the tanks you are not really increasing your volume. Each tank will evapoarate at approx the same rate and very little water will exchange. It wouldn't take much, just a small powerhead sucking from one end tank and discharging in the opposite end tank. The other possibility is only removing water duri ng water change from one end tank and only putting fresh water in the opposite end tank. However, between wc you really won't have any water movement.
