I have a cyano problem, and im thinking my phosphates are feeding the problem..and its probably leached into my rock and sand so i need to aggressively use gfo to try to counter act that abd try to remove it.
I just re-read this part I quoted above - don't assume that phosphates are necessarily the cause of cyano. They could play into it but I've had 0 detectable phosphates and had cyano. I just recently changed my sandbed and went through a carpet of cyano all across it, and eventually it went away when it consumed up whatever it was eating. Carbon dosing IME will also feed cyano at a certain point.

Its definately a water issue, its a 5or 6 step purified water system that i buy from. So its not RODI, im looking into getting a rodi system really soon. I do weekly WC, i have a coralife 220(not the best but rated for alot more than my 46g) and yes id assume the rocks are leaxhing along with the sand, i bought the tanks already set up and running and he said thats the water he was getting and it was fine. Well obviously i learned later on it wasnt. And i feed once a day a piece of seaweed and a cubeof mysis/brine, or mysis and bloodworms, all thorughly rinsed before being fed.
Okay now we are getting somewhere. Do you know what the TDS is of your water? 0 TDS will help, and yes rocks that are not leaching will not help too but I wouldn't worry about that now, get 0 TDS source water and go from there, and above all else stick to a regular weekly water change schedule. For the short term you may want to try and grow some chaeto in your symp if you have one to help with nutrient export. Make sure you keep your skimmer clean and running optimally, and be patient!

But i need someyhing to control the phos while i get the water issue under control, protecting me from a potential algae outbreak, and bigger cyano problems. So aggressive GFO use it is! Lol
Seems like a reasonable short term solution. I use GFO and don't consider it a band aid, I use a small amount to help. But if you have other sources of potential problem, it is just treating the problem and not helping to get to the cure, but sounds like you are aware of that and on it. Running large amount of GFO have caused problems for some people, as it can suddenly strip too much nutrient - just be careful not to go overboard, and to back off it a bit once you get things under control. I ran the high capacity GFO for a bit and it caused base recession on some of my acros (I can't prove that, but that was my observation and only logical explanation).
