Skimmer going crazy

[MadReefer]

I dosed Prazi for flukes and fter 3 days of no skimming and no GFO turned the skimmer back on an threw carbon cartridge in fuge. It has been 2 days and the skimmer still going nuts. Tank looks like it's snow and my red cap is starting to turn white, was fine until now. Should I add new GFO back in and/or water change?

Can do both, turn the skimmer all the way down, it will be a few days before it goes back to normal. Also, check your salinity, if you're dumping the skimmer cup each time it fills chances are you're lowering your salinity

Thanks Art. have not dumped much water because e HOB skimmer is odd for overflowing. It has a hole on the side and if you raise the cup above it the water flows thru the hole into the return chamber. Which is why it looks like snow. I have been adjusting it constantly for two days. I did a GFO about an hour ago and making 10g water now.

No other hard corals are showing any signs?

Thoughts:
1. Too much light.
2. Alk, Calc and Mag off.
3. High N's and P's.

Paul, that is the only one. Acros were always iffy in my tank. I did cut the light back to get more blue but washed some colors o. Fish. So I am running the lights at 40% across the board.

After WC and feeding here are some numbers.
PH 7.7
ALK 7
NITRATE 0
NITRITE 0
CALCIUM 560 - been like this for a while
AMMONIA 0.25

Woa.....that ammonia can't be real. Are you using API test kit for ammonia....they are known to give 0.25 when in fact there is none.

 

[MadReefer]

That kit is old so cannot say how accurate. Initially looked like 0 but after 3 mins or so was looking like that. Again it was after feeding and stirring up sand after a water change.

It will come back, I hosed mine with h2o2 and bleached the whole thing before, came back in a few weeks
