I have broken down and replanted my 55 gallon tank.I am using Miracle Grow organic Potting soil,covered with decorative pebbles. I have two AH hobby lamps at 6700k lamps. photoperiod is 10 hours. My plant growth is very slow and all I am growing are algae on the glass.
The water is tinted but clear.
I keep cleaning off the glass and with in a week the algae has returned.
I have changed the water twice and the tank is about two months old.
What is the limiting factor here? I am a believer in Mrs Wasteds method and I am stumped.Any help would be appreciated
