Well since rescueing a RES & Painted we went to petland and bought a 75Gal tank for them. The male RES should be gone soon (zoo) too. Once he leaves we're planning on moving the painted over to the 55gal and bringing the two RES over to the 75gal.
I'm currently assembly a custom made stand (2x4's & birch wood). Should be done soon, then I'm going to work on building them an ATBA out of acrylic. Also the stand will hold a 90Gal if we ever upgrade.
Stay tuned for pics.
It's gonna have a 4+ w/ Carbon pads, 501 w/ biomax, and a mini water fall filter for two weeks. The FX5 should be here late next week. Planning on loading that up with biomax like the 404 on the 55G.
