I would also take a look at the Water you are getting. Alot of the store bought filtered water is bad. Do to the fact that little maintainance is done on the water filter. Try checking the Phosphates of a bottle you just bring home. This will be a good indecation of other problems with the water. Also over feeding will create Nitrates that algae will feed on. Your test will read very low for nitrates but the algae is feeding on it so the results will always be low. In the past i have used a airline hose during water changes to such the algae up. It comes back but each week it gets less and less. It is also very time consuming but what can you do
