Not using rodi, usinh wster from 4 gallon bottle i buy from local aquarium storeHow do you do your top off? Do you have an auto top off setup or are you doing it manually and are you using Rodi water or tap water or something else? This also contributes to the hair algae if you are not using Rodi water
What are the readings? What are you testing and with what test kit?Everything is measuring good
Thanks i will do allWhat are your tank parameters? Your nitrates and phosphate levels and what test kits do you use? You're going to need to scrub the Rocks as mentioned but I would also once you're finished with that dip them in a hydrogen peroxide and Rodi solution provided there's no coral on them. It's one bottle of hydrogen peroxide to a 5 gallon bucket. Dip them no less than eight hours and don't do them all at one time do a few of them every 3 to 4 days until you finish with all of them. When you're done dipping rinse them really well in Rodi water and place them back in the tank. You're going to see a nutrient spike in nitrates and po4 because your hair algae will no longer be taking it up so you will need to be doing several water changes or larger ones. Lower your light levels or time that they are on and lower your feeding.
please also go to the members tanks area or Nano tanks area and create a build thread and tell us about your tank. Having one of those has a lot of benefits. You can treat it like a journal and be able to look back on it as well as get input from other members and when something like this happens we can help you more quickly 
Would it be easier to just toss the rocks buy new, and start over eith rodi water?So in a nutshell here's what I think. Your lfs (local fish store) maybe selling you Rodi water over 001 or 002 TDS, they are doing your testing with API test kits which are garbage unless fresh and not being open all day. Which more than likely they're open all day at the lfs. You won't get accurate readings from those tests. Your lights are not on too long they are fine actually they should be on longer if you're supporting Coral if not and it's just fish it's not a big deal. You don't have the proper clean up crew and definitely need snails. You need to invest in at least a Red Sea test kit and do the test yourself for better accuracy. And if at all possible see if you can find an Rodi unit that you can hook up to your sink. Whether it be used or brand new you need at least a three-stage system plus Di. I suggest that you get some ferric oxide or phosguard and a bag to put it in and put it in your sump or the back of your BioCube if that's what you have in the path of the water flow. That will help keep the phosphates down. In the meantime do as I suggested as far as dipping your rocks and getting rid of what's there now. But if you don't get a handle on it it's only going to get worse.
They do itDo they also do your testing for you or do you do it?
Even if you buy new rock you're still going to go through the ugly stages maybe not this bad but you will still more than likely get some sort of algae. Personally I have been where you are but with a far bigger tank. I had over 250 lb of Rock and did this treatment. That was three tanks ago and that rock still to this day does not get algae on it. I would suggest cleaning up what you have. Your money can be better spent on other supplies that you need.Would it be easier to just toss the rocks buy new, and start over eith rodi water?
