Mushrooms letting go

[kimo4848]

Some of my mushrooms are comming off of there rocks. Never had that problem in other tanks. Just a couple of them so far.

0-ammo
0-nitrites
0-nitrates
8.2 Ph
420 cal
temp 79.5-81.5
running a GEO reactor also
I do weekly water changes 10% on a 120g with R/O water
I add Iodine weekly with water changes
running a bubble master skimmer 160
2-250w halides 8 hours
atinics 12 hours
moon lights at night

Could it be to much current on them? There is alot but the waves go back and forth. I thought it might be to much light but they seem to like it, they stand up high. SPS's and the LPS's are growing very fast even my Frog spawn spreading new heads all the time.

I did buy this set up from someone else about 4 weeks ago and she had it up and running for 6 month.

I did lose my clam today, yesterday he was out and very happy. Any advice.

uhhh

What is your Alk and Mg level at?
ohh and PO4?

do you dose a strontium sup? Someone correct me if I'm wrong but I believe Iodine and Strontium is good to keep mushrooms attached and for growth

I add Iodine but not strontium, I don't have a test kit for alk or mg. I'll see if I can get one this weekend.
