For circulation I've seen a couple of tanks setup with bottom drilling that plumb two intakes in the rear corners with that lateral piping covered by the substrate with the intakes mostly hidden by aquascaping. In those tanks there was a spraybar laterally across the rear that seemed to point upwards and towards the front that seemed to provide adequate circulation. However if that didn't work I could always provide an over the top return and hide it somehow. Any thoughts on the success for either?
I sent an email to www.glasscages.com
asking for more info. They apparently temper the glass after drilling and before assembling. I'm planning on their low iron glass for the front and sides (Starphire.)
As to larger size I originally wanted a 120g but I don't have the interior structure in the available locations in this house to support the weight. A deeper 90g is just too deep for my arm length.
My only aquarium experience is as a teen (decades ago) and more recently around 2002 when I was fiddling with some small tanks after retiring. All of that taught me that fewer things over the edge of the tank would work better for my innate klutziness.
I'm targetting lower light levels, MTS and minimal dosing, low water change and trimming frequency to minimize my fiddling and just enjoy some slow growing aquascape and soothing pretty fishes. The CO2 is really to help with minimizing issues rather than supporting high light, high growth flora. I don't think relying on Excel for carbon would work for this size tank.
I set my goals probably higher than I might reach but if I don't aim high it will likely end up one of my typical messes. So I'm trying to get this right from the start with good research, planning and good advice from all of you.
I'm planning to do an initial setup in the garage to "proof" all the setup and connections before emptying the tank and moving to the office.
Glasscages also has some oak stands I'm considering.
thanks to all!
