So i have had my tank up and running for more than 6 months. i introduced a new anemone a few weeks back and it deflated once or twice, but always came back. Now it seems to just be bunched up. I have another one that seems to be doing fine. On top of that I have an huge red algae bloom that i've been treating every few days for past 2 weeks. I cant seem to get it under control. I'm using chemiclean and doing on scoop per 10 gallons. i have 55 gallon with 20 sump. ive remove the carbon and tested all my levels, nothing seems off aside from a super low PH which i've never been able to get up. Ph is now right around 7. Am going to do 20% water change with my RO filtered water, but am starting to really doubt myself as a saltwater tank guy since i cant get this algae under control.
