So I’ve been struggling with extremely high phosphate in my tank 1.0 ppm+ my Hanna checker couldn’t read it it was so high... I bought some brightwell aquatics PO4 xport cubes to hopefully lower down the phosphates since I don’t have a GFO reactor nor have room for one in my tiny 10g sump.. over about 2-3 days of being in there I tested phosphate again and read .60 ppm, 4 days later I checked it and it’s now reading .62 ppm so it appears to have stopped going down, I already have the max recommended cubes, so don’t want to add anymore, but should I take them out and replace them with new ones? Would this maybe help bring the levels down more without adding too much of the blocks? They recommend 5 blocks for ever 100 gallons, I have 4 in my 80 gallon system. Also have refugium running with cheato but doesn’t seem to be growing too too fast, it’s growing, just slowly. So advice? My levels have been .90 ppm+ for about 2 months now and my corals are looking a lot less colorful and little less happy.. so looking to get those phosphates back down to near 0. Any advice is appreciated
