Gray Fuzzy Looking Stuff...Talk me off the ledge

[bdub22rhp]

Well my tank started off great, but recently has been a disaster. I have UV, run carbon and GFO, have thriving macro algae in my sump, ozone, and an oversized skimmer. I started my tank with dry rock and it will be a year old in July. Well about 2 months ago I got amphidinium dinos from what I am guessing was low nutrients as my phosphates and nitrates were undetectable and low respectively. So in an effort to grow other things to outcompete the dinos I removed my GFO and started to overfeed the tank as well as added Fiji mud to my fuge to try to boost my microfauna. Well my phosphate crept up to .19 so I started a smaller amount of GFO back to try to get them back to around .1 or less just not undetectable. However in the mean time I have noticed I am growing something new. The best way I can describe it is it looks like tiny gray ferns. It only grows in shady areas and likes to be low on my rocks. It especially likes the dark holes and crevices in them where there is no color or coraline. I first thought they were hydroids, then a sponge, and now possibly chrysophytes, but none fit the bill entirely as these things come off very easy. They can be blown off with a turkey baster or a target feeding tube. If I google gray fuzzy stuff in saltwater forums a bunch of hits come up with people having this, but it is never IDed nor said to be good, bad, or don't worry. I have recently lost 2 rock nems and am showing some skeleton on some of my euphyllia. Also my acans are ticked off and they never are. My CA is 433, Alk steady at 9.6, and MG is at 1350 as I dose all 3. CA and Alk tested with Hanna and MG with Elos. .19 Phosphate is also from a Hanna. Please help as I am at wits end. Water changes are bad cause they boost dinos. My CUC won't touch this stuff. Have hermits, astrea snails, and nassarius snails. The green you see in the pic is only on the surface of my rocks and it slowly turning pink.

Your tank is still cycling and will be doing so for a bit longer. Mulm link

So leave it be? I really didn't notice it until I added the Fiji mud. Just thing to figure out my rock nems disappearing and my acans ticked off. I went super slow in adding things and everything was flourishing till recently. Ibguess my dinos could be affecting the whole system, but all my readings about amphidiums say they are the least toxic.

There is link to a write up. Leave it alone and it will go away. As far as the diano, what kind of lights are you running

I have 2 radion gen4 xr15s over a 90 gallon.

Cut back your white spectrum to no more then 30% for 5.5 hours and the diano should disappear in about 10 to fourteen days. I had the same thing going on for sometime did the something and diano are gone along with cyano.

I'll give it a shot. I have been siphoning through 5 micron socks and putting water back into try to help decrease while trying to grow other things in a dirtier tank to out compete them. I can change the whites very easily. Think there is a white and a warm white on the radions.

both then, you can run you RB and blues up high. I have the Hydra 26hd's. Same company here is how I run them now

I'll give it a shot. What do your numbers in the spreadsheet correlate to? At first I thought it was percent, but them saw them over 100 so don't think it's percent.

It is percentage. The hydras one can go over 100% and us energy from the other channels. I though the Radon could do that too?

They might be able to. I've just never tried to go over. I have been running their coral lab LPS template and everything was doing great. New heads, new skeleton, great extension then boom all with in a month things have gone to heck in a hand basket. Starting with dinos. Although the gray stuff isn't a worry anymore. I'm guessing the overall unhappiness of my corals is the high levels of phosphate.
