Well Yesterday Melissa called me and said there was some cyano on the sand. She had the nanny vacuumed it out. This morning I looked in the tank and there was more. I vacuumed it out and checked the tank water and RO/DI water for PO4 Tank registered 0 and water straight out of the RO unit was .01. I had replaced the filters 2 months ago but I went ahead and replaced them today. Am I correct in assuming this was the source? Was my tank getting rid of the PO4 by filtration and also the cyano? I also took the filter media out of the wet/dry tray and replaced them with new poly filters. Any other suggestions or comments?
