Just a further followup to my algae hell. I've got a fair amount of hair algae on my rock and even though I scrape the front and side glass every other day you can't see anything within 2 days.

-Brand new 10K Hamilton 175 w MH and actinic vho. (mh changed yesterday, vho 2-3 weeks ago)

-46 gallon bowfront
-Good circulation (scwd probably 600 gph turnover)
-Red Sea Prizm skimmer producing brown gunk
-eheim with sea chem phosguard and silicate remover just to be safe for the past few days
feeding every other day lightly
crew of blue and red hermits eating like there's no tommorrow
nassarius snails moving around the sand
some mexican turbos and other snails that seem to being dying slowly
There may be a dead small brittle star that I cannot locate

water parameters

0 amonio
1.025 salinity
0 phosphates
0 silicates
0 nitrates
400+ calcium
alk on the high side (5 on the lower scale where nsw should be like 3.9)

Tank is about 4 months old
Inhabitants
1 small percula
1 small hippo tang
1 hammer coral that is doing ok...

Is this just the normal new tank syndrome? Anything I can do to help get this under control?

How long do you leave your lights on? When I get the Green Hair Monster I just turn my rocks over and Bam! ....its gone. No crapola. This works for me. I also have three large Turbos that do a great job of eatin algae off my rock and glass. They are about 1" and I have had them for over a year now.

The answer: RO Water, RO Water, RO Water. I had the same problem until I got my RO/DI unit. Once I pulled the last of the hair algae out after switching to RO/DI water, it has yet to grow back. It used to grow back on a weekly basis.

You might want to change your di with tds at that level. Test water out of the RO prior to the DI to see the tds level. Sanils as said earlier are good also, but I keep less than the "recommended" because that way there will always be enough food for all. HTH

Is that 150 prior to the DI? and 8-10 after the DI? If so I would say you have a bad membrane. What is your tds right out of the tap?
