Do water changes. Siphon out all the detritus and as much of the hair algae you can. If you can, take out the rocks that has the hair algae and use a toothbrush to scrub it off. Make sure you have good flow no dead spots.

the hair algae is actually on the reef sand only. i retested the phos and it was at .5.... will try the phos reactor. also my tds on my rodi unit is 000. so filters are still good. besides they are only about 1month old.

	RODI High quality filtration systems used to purify tap water before it is mixed with salt or added to the aquarium for evaporative top off. Most municipal water supplies contain unacceptable levels of Nitrate, Phosphate, Lead, Chlorine, Copper etc. It is critical that these impurities are removed as some are toxic to reef organisms and others fuel algal blooms that can quickly overtake a reef display. Again, there are many brands and many configurations to fit most applications.

I just had the same problem. All of a sudden in about a week, brownish green hair algae broke out all over my tank. My api test puts me at 0 phosphates, and 10 nitrates. I go to the lfs to test and they put my phosphates at 30. I cut my lighting back and have done about a 40% water change over a few days and things are already looking better.

Any recommendations on some better testing kits, esp. for phosphates?

what is the recommended light cycle. i think i might be on for tooo long. mine are set at actinic go on at 6am, 10k go on at 6:30am..10k go off at 9pm and actinics are off by 9:30pm.. i think thats way to much but im not sure so i am asking if that has anything to do with it...

This is a Pain but can be gotten rid of, Bob's idea about a phos reactor is good to lower the levels but is not solving the cause

your readings are never 0 for phosphate or Nitrate, hence the hair algae to solve your problem do the following

1) Get a really good test kit you can get ELOS test kits from Marine Depot

2) Assuming you are using and RODI test the salt water you use for a water change. (this is ti determin if you are adding phosphate when changing water, you might need to change salt)

3) If your mixed water is good do a large 50% or more water change.

4) Feed less

Phosphates will always be in your tank because its a closed system, only water changes and good husbandry will keep the levels low. To deal with the hair algae that is there get hermits, emerald crabs, maybe a tang.

[Chiefmcfuz]

Aquarium Pharmaceuticals = API

No they aren't that accurate

	SPS Small Polyped Scleractinians - Sometimes known as Small Polyped Stony corals. These are hard corals that have extremely small polyps. They are typically on the difficult side and require Metal Halide lighting or dense Power Compact or T5 arrays. These corals are prized for their rareness and ability to be easily fragged into multiple colonies.
