Here's my 600G DIY. Plywood & Glass (96x48x31)Aquascaping still isn't done, I'm waiting for the weather to warm up so I can go find some really Big pieces of Driftwood. The only plants will probably be Amazon frogbit, and Jungle Vals if the Silver Dollars let them grow and don't mow them down.
Full tank Shot you can just see the Silver Arowana at the top left side of the tank at the surface hes about 4.5-5" atm. The Blue is the insulation till I get the drywall up.
Silver Dollars
Metynnis argenteus
Future Inhabitants 2 of the 3 Peacock Bass either Cichla Orinocensis or Cichla Moloculus will be easier to tell once they grow out a bit more. They are currently in a 29G training them on dried food.
Once the Driftwood is in and the aquascaping done I'll hide the heaters and the FX5 filter pipes. I'll probably be getting an Oxydoras Niger this weekend for my birthday for cleanup.
Filtration is a Fluval FX5 mainly for mech filtration, and a DIY 70G trickle sump with about 20G of bio media in it atm being run by a Gen-X 8500 submersible pump (8500lph/2245gph). I'll be adding about 20G-30G more bio media.
Heating is 1000W and tank temp is holding steady at 82F. 600W held the temp perfect in the fall in but with the cold winter weather I had to add a 400W heater to keep the temp up.
Lighting is your basic T12 Shop lights 4x40W with GE Plant/aquarium bulbs.
Substrate is 400lbs of Lowes Pea Gravel dirt cheap @ $2.59 for a 50 LB bag.
There's also a baby Oscar in the tank about 2.5" who's hiding because he's mad at me for taking his 2 other 2.5" buddies out because they were ganging up on the Arowana. Just like rotten teenagers!
