I'm noticing some color change (green to brown) on my montis and a slowing of growth all around which seems to be a classic phosphate problem. My phosphates are around .05 ppm according to the cheesy little test kit I have so who knows. The tank is 10 months old and I did not start it with any GFO. Here's my two part question:
1. I don't have room for a reactor as it is a nano tank so can I use a GFO pad in the overfow?
2. How can I add this to the system without running the risk of RTN or STN in my corals?
