Well I have a 55gal. with sand substrate. I have 4 albino cories, 10 har. rasboras, a bristlenose pleco and two baby angelfish. I have a couple of little plants that a friend gave me and also a medium clump of java moss. Anyways my little plants keep comming out of the sand (prob. because of my pleco) and its kinda making me mad. Also I don't really see any growth at all. I have only one side of the tank planted with lights over it. I have 2X55watt. 6500k CFL. over the planted side. Like I said I don't see much growth, its only been a week but I figured with these lights they would grow good. The tank was just recently moved and the sand is completely new. The java moss is starting to get white fuzz all over it and the roots of the plants that are exposed from being disturbed are getting white fuzz. I have a pressurized CO2 system but I'm having a hard time getting it setup. I just bought a washer for it today but it doesn't fit of corse. Plus I don't really think my solenoid is working right. Anyways...does anybody have any suggestions? Thanks!
