Help! :? I was given a 90 gallon reef setup about 1.5 years ago and I have been constantly struggling with it. I can't seem to stop the hair algae growth. I don't know how much live rock I have, but it seems like a lot. It is stacked to the top of the aquarium from end to end. I have an overflow with a sponge filter that directs the water over some bioballs. I have a phosphate sponge and a protein skimmer. I have more than 10x flow with two powerheads. I have tried cutting back on my lighting (2X175 watt 10,000K MHs) and that helps , but then the algae comes back . It certainly seems to help when I do water changes, but I am doing the 10% per month and I don't have time or money to do much more. I have worked fairly hard to keep my chemistry correct with the help of this forum. I have reasonably good corraline algae growth. My phosphates are .03 ppm or below and my calcium is good. I can't detect any nitrates or nitrites. My substrate is the one that came with the aquarium. It is black and white and looks like crushed coral to me. I don't have very much as I remove it often when I do my cleaning.
I want to make the move to a DSB, but I would like to hear from some experienced folks to see if that is the right answer. I have also read here that bio balls can be a cause of nitrates and I am confused by that.
Where do I go from here? :?
Thanks in advance for any advice.
