im only doing changes every two weeks or so and i just started that...the lights are only 250watts of pc so i doubt thats why ..im using the plants as a skimmer so therefore i dont have one i like the plants alot and if they die out then im gonna have to get a skimmer...geez one more thing to worry about..i wish they would take over cause then i could sell them to the LFS and have plenty aswell...but i seems im losing them alllook at this photo compared to previous:

oh and the reason why there wasnt so much growth on the plants is cuz the photo was taken days apart

i will check out vanquish's thread for sure thanks
