the main problem was all the time i spent using tap water on my tank because in the last few weeks since i been putting in low ppm ro water into the tank rather then the 100 or so ppm i was doing,my hair algae to me at least looks like it isnt growing in as fast and i use phosguard....according to my tests and AC i dont have nitrates so it's just phospate for the most part that is feeding my HA.....i'd love to not feed my tank but you should see gloria (female clown) she doesnt stop wanting to eat, melmon (male clown) hardly gets any food and mr. poopers (blennie) all he does is what his name states lol and honestly i've seen poopers bite and spit out my HA so i dont know lol
