frogspawn bleaching

[e46er]

i have a 120G with about 3000 G an hour going thru it maybe more im not sure what my CL is running at

i got a frogspawn 6 months ago and had some HA issues and he was thriving lotsa color and quite large
now the HA i took care of 2 months ago redid rockwork ect. and replaced my 150w MH also started vodka dosing.

now he is bleaching out and overall not happy i thought maybe it was a light or flow issue so i moved him to 3 different heigths and 3 different spots to check if he was unhappy with the flow over the past 2 weeks he has just gone more white and shriveled up any thoughts or ideas?
i have other LPS and SPS that are doing great and fish are all happy..............im confused

I noticed from your signature that you have clown fish....are they hosting in the frogspawn?....If not, then the first thing I would do is take it out and dip it....are you running any kind of phosphate reducing media?...If so what brand are you using?

No the clownfish do not host in it

what would you reccomend dipping them in? Lugols solution??

I also use rowaphos in a reactor with a 160 gph powerhead
