This is my first tank. There is about 140lbs. of lace rock that I got for a dollar a pound. 5 fish don`t know what they are yet, sorry. A 300gph powerhead, Ehiem 2224 canister filter and in about 3 days will be getting a Rena XP3 to run in conjunction with the Ehiem. For substrait I went with Filter sand from a pool supplier, 8$ for 50lbs. Was thinking of taking some rock out and anchoring in some silk plants into the egg crate? Hope I am doing this right my first tank and all.
