Is this Diatoms?

Pellets not real good at po4, might need some GFO.

It looks like gha with cyano. Check your phosphstes and you can lower them them with gfo. If you use gfo slowly add it to your tank because you can shock your corals. Biopellets mostly work on nitrates, also make sure your using the right amount. Too much can strip your water.

To many Bio bad? I have 2 TLF reactor 2/3 full for 150g display, 210g total volume

Looks like Dinos to me. I would suggest doing some research, but best results I had were achieved by doing the following:

Lights out for 5 days (complete black out except for 15 minutes a day for feeding)
Raise pH to 8.4 or greater
Using Hydrogen Peroxide
Filter Sock
Run Carbon for toxins
Water change 30-40% after lights out

Hi,

*1 on dinos.

The thing with dinos is that there are many different types, some toxic(red tide is a dino) and some not.
Turbo snails and trochus snails will eat the non toxic variety.
Lights out regime may or may not work
Chemi Clean or Algae X may or may not work
peroxide works but is potentially dangerous and will kill shrimp and xenia.
make sure your tank is kept clean of detritus and regular water changes are done.

Here is some reading for you:

Cheers,

ps If your Phosphates are high try some Foz Down. Safe, cheap and easy phosphate control.

Hey Jason, I've seen you mention the use of hydrogen peroxide a few times, and I know it is a good algae killer. I had a bad outbreak this past summer, and almost resorted to that.

But the concern I have (and it could be completely unwarranted) is that it might upset the eco-balance (for lack of a better term) in my tank. Right now I have various fish that graze on algae, and perhaps my coral require some (in phyto form?) too. And don't coral grow some algae internally?

In any case, I decided to fight the algae with lowering my P04 and manual removal, and so far have always managed to beat it back that way (have had this problem before, and much worse actually). My recent transfer of my Kole tang to my upstairs tank, has really helped.

I still have a bit of algae here and there, mostly in spots that I can't reach with my tooth brush, but seems to be under control now. My P04 is back down to near zero. And I think little bits of algae here and there give a more natural look, too.

Anyway, would like to hear more opinions and discussions on the use of hydrogen peroxide and if there are any negative effects on the tank eco system and corals.

I had dinos. I did 3 80% waterchanges. One each day. By the third wc there were no signs of dinos. So i did 2 more 50% wc and never had an issue again. And prior to that i had tried many different methods of killing it that did not work. This is just my personal experince but that worked well for me

I think I need a new clean up crew. Mine has pretty much dissapeared. Prob gona make a call to JL today. Just don't know what to get anymore? I used to have lots of snails and a couple blue legged hermits, but now I don;t see any anywhere. They were getting pretty old too, Havent added any in over 5 years. Never really thought about them
