Alo pet stores are a good sorce of good water. Many pet
stores sell RO water, and many also sell premixed ro salt
water. As pointed out,making regular water changes with
this low nutrient water will help with the hair algae
problem, as will the protine skimmer kept working, and
algae eaters. The nice thing about getting the water at
the pet store is that you don't have to worry about
whether it is a sutible source of water or not, and also
the option of the convienience of geting it already mixed.
But be sure to seak out a pet store that is reputable, as
many will sell you down the river.
