Well.. starting a thread, but it is still in the "thinking" stage... What I have in mind is to build a new canopy for my 75 gallon planted tank... what I aim to do is to build it tall, and mount 2 10 gallons side by side over the lights. They will be cased out, so it will appear to be one long tank over the top, and I will either use them as grow out tanks for babies, or just put other fish in there... It will all be one system, as I will pump water up from the 75, and through the 10 tanks... let me know what ya'll think... and then I will get started!! lol
