Where are your phosphates comming from to begin with?
More than likely it is your water sorce so why not install an RO filter and get rid of your phosphates before they can even get in your tank.
Even the cheap $100 units that are on eBay work pretty well.
This is what someome on here said, Not to repeat what othersstated, butI think maybe the better question is (and we know you have a lot of phosphates or you wouldn't have cyano which is actually a bacteria) is what is their source?Low water flow is probably also to blame. Here's some thoughts:
1. It can be in the flood (flake is terrible) or;
2. the water (tap is loaded with them and using an old RO/DI unit with a worn out membrane) or some cheaper salt mixes are high in phosphates as well.
3. Try turning up your skimmer so it makes a wet skimmate instead of a dry foam.
4. Rinse your frozen food really well before feeding with old SW.
6. Increase the amount and frequency of your water changes, and as a last resort;
7. Add a phosphate binder.
8. As you're already aware, change the bulbs.
If you're seeing negative effects to any corals or other inverst whenyou add the binder, then you should add less (only submerge half the bag), leave it in for a shorter period of time, or not at all. Good luck!
I would turn off the skimmer and then do a large water change afterwards with either RO/DI or distilled water only. What was the reason for using this product? Thanks for re-posting my original message, and it will work if you follow it. Good luck and keep us posted.
from what iam starting to figure out was when i did that big water change a mont ago with all fresh ro water, that had something to do with it, also the addition of the new lights, also i found out that the water that i used from my lfs may not have been what thay said it was...
