I'm about ready to give up. Over the past 2 weeks my tank has developed an outbreak of brown algae all over my rock, subsrtate, and glass. Also my nitrate level won't drop below 20 ppm. I thiunk the 2 are related but I can't seem to shake the problem. I've done water changes up the ass, tried cleaning everything, and my CUC doesn't even seem to touch the stuff. I am getting so p'd off!
