This is an abrupt start for a new tank thread. My custom made "180p" (72"X18"X18") has been rescaped and running for 2 months now since I broke down the old one This one. IAPLC 2011 rank 403 roud: Unfortunately I some how lost all the setup shots I had taken so none to share at this moment but the specifications are Tank: Rimless 100gal (custom made) Substrate: ADA ASII (normal & powder) Filtration: Eheim Pro III (had 2 units. I broke. One has been sufficient but added a Hydor pump to added circulation) Light: 4 39W T5HO for 8 hrs/day, 3 150w MH (6500K) for 2 hours during mid-day Flora: Elatine Tiandra, Fissidens fontanus, Mini pelia, Flame moss Fauna: Cardinal tetra, Emerald eye rasbora (this is very lightly stocked at this moment to accomodate the fish from my other tanks to be housed temporarily. Now that they are gone, I will introduce a bigger school of cardinals soon) Hardscape: Local rocks from Tennessee. Not sure what they are but the guy who provided said petrified wood. Not sure of that and it did not affect the PH or GH either. This is a shot from last weekend after 2 months of growth and a good trim on the elatine. Sorry about the poor picture quality.
