The change that I noticed sense doing the first dose is that Euphilias are not opening up to the full extent and RBTA is not sprawling everywhere. SPS are unaffected completely. I have a couple of issues that might be too blame though. I overdosed dosed Aquavitro Ions (magnesium + trace) and had to switch from dosing my usual fusion 1 to Aquavitro calcification, which contains citric acid. I also had a frag of zoas fall off the rock and was carried away by a goby, which presumably means palyotoxin got released in the water.
I believe I see some improvement in the brown algae covering the top of the rocks so I added one more 15ml dose last night. I am running carbon and replaced the GFO. Skimmer seems to be pulling much more crud then previously.
