I have a 125gl tank with Discus, angels, Tetras and some Golden snails. The tank has been in operation for approx. 6 Months. I have it fully planted and have only fair plant growth. I have several questions. Listed are the Specs of my system.
Eheim wet/ dry canister filter. Using spray bar against back of tank, very little surface agitation and minimal bubbles.
Fluval canister filter with outlet hooked to a sandpoint co2 injection system.
I have two pendent MH lights suspended about 8 inch over the tanks, 175 Watt each.
My tank is open on top.
Dupla Laterite and # 1 Gravel over this.
1. Would I have better plant growth in general with a glass cover over the tank?
2. I recently added Angels and they seem to always be on the surface. Could this be to much CO2 or do they usually hang on the surface?
3. I have a small algae problem and recently added 6 Golden Snails. They seem to be doing a job, but I am worried that they may eat my plants?
