Currently I’m letting my tank fallow. I’m on my 5th week and I got till 72 days. Had ich and trying to get rid of it. When I first started a while back I used tap water to fill up my tank knowing better. I had an insane amount of algae I’m my tank. Did some research and got an rodi unit. I had my rodi unit for quiet some time and didn’t change the filters. When I took all my tangs our of the tank the algae started to get bad. I tested the rodi water and it was testing for 0.5-1.0 for phosphates. This is when I got new filters and it’s now reading 0 phosphate in the rodi water. I had a small CUC that consisted of about 6 emeralds and 7-8 snails/hermits. I recently went to my LFS and got 11 more hermit crabs and a cleaner shrimp. Nothing seems to help. I’ve been getting an insane amount of hair algae. My tank is in the basement so no where near windows. I’m using rodi water with a 2±6 tds. Now I had my lights sitting close to my tank surface so I decided to higher them from another reefer suggestion. I have ocean revive t247 I’ve been trying to increase the light that I’m using. I was currently at 25% blue and 6% white but I’ve bumped it up to 35% blue and 16% white. I added a refug to my sump Friday. I added a LED light with chaeto. I checked my test and it seems like my phosphates are roughly 0.5. I’m thinking the lights are increasing this because before I was testing at about .25 and the algae wasn’t as bad. Now I did buy this rock back from a guy on Craigslist that was selling his tank and I managed to snag the rock. I’m not sure if the rock is the reason why I’m having problems or if it’s because I was running bad rodi water for a while. I’ve been feeding my tank pellets every day to keep the cycle going and to give my CUC some food. I got a filter called poly filter and it turned brown in a few days. About to change it out to floss in the next few days. Any help or suggestions would be great!
