Algae, question

[alexwolf]

Is there something that eats them?

[TAXMAN]

I want to know if there is a predator for them too. Maybe a crab? I hate these things. I even have them on several of my snails. 1 snail has 2 on it.

Gotta say I am seeing the same thing. Everything was running great and then bam, almost overnight this stuff starts to cover everything. I have been battling this thing for 4 weeks, so far without a whole lot of change, I syphon and hoover daily, but by the next day it is back. I am doing 10G every 2 days of water change. Looking over at reefcentral, I am coming to the conclusion that this is actually dinoflagellates, which is apparently really bad news.

Here's the rundown on my tank FYI.

75G Oceanic RR bare bottom, 75# LR
4 fish (dwarf Lionfish, lawnmower blennie, coral beauty & Flame Hawk)
Feeding every 3 days very lightly4 emerald crabs
50 assorted snails (astrea etc)
No suppliments
20G Berlin Sump
Aquamedic Turboflotor 1000 Skimmer
Coil denitrator
15G Fuge, running 24/7 with 24W Coralife 50/50 with Macro and live DSB
18W UV added recently
Running GAC in sump
Running silicate removing stuff (forget name, looks like mud) in sump
Lighting, all <2 months old, 2x175W 14K hamilton HM, running 4 hours/day, 10K 96W T5 running 6 hours per day, Actinic 96W T5 running 6 hours per day
Temp 80F +/- 0.5F (controlled with Aquadyne Octopus)
PH day 8.34, night 8.26
SG 1.024
DkH 13.5
Calcium 350 (Getting Kalk reactor soon)
Ammonia, nitrite and nitrate 0
Phosphate 0
Silicate (1PPM - high)

I will try for a bit longer, but so far this outbreak has been vigourous and persistent and is starting to get me down. Wife is also moaning as I spend all my time with my hands in the tank rather than being with her! Any ideas most welcome....

I've got it, I'm going to go with more skimming, reduced feedings and increasing PH.
