ok I did my first water change today an it was so easy rather than my old 150 water changes.
Before i did it there was 7 ppm nitrate im going to test a lil later just to let things settle, but tis coming along nicely, got some phosphate and silicate remover to try it for the hair algae(too high phospates) and cut my lighting down to 10 am till 7 pm.
