Planning a 75 Gal Cichlid tank - filtration ?

Sookielee

We were planning on having the same water parameters in both tanks, not different. The 45 would only have plants no fish, well maybe some snails. I thought the U-tube would prevent one tank from becoming empty and the other flooding my dining room in the event of a power loss. I take it this is mistaken?

Oh well, I will pass along the feedback. It did sound like a cool idea to me, but I do not know diddly squat about aquariums. Guess we should have taken the google searches coming up with nada to indicate the validity of the idea. Thanks a million!

One thing we thought of wouldn't the idea be like turning 2 tanks into 1. instead of a 75 and a 45, we would have the water volume of a 120?
