How did you make out with the diatoms? How's the tank doing?
Hey
@Sleeping Giant thanks for the post. The diatoms cleared out after a week of just scrubbing and water changes. Things seemed to be going well but all was growing slowly. I got a lot of algae so put in a cleanup crew and lawnmower blenny which helped but then the Blenny died. Not sure what happened as all the other fish were fine.
I started dosing Vibrant and that really helped clear the algae. Some of my corals seemed to be reaching to I increased my light and that brought back the algae on the back glass. I should have left it in hindsight.
During my water change I scrapped all of it and starting using my Phyton to suck it up as I was taking water out. I should have done a small portion of the glass but I only managed to get like 25% to 30% of the scrapped algae and the rest fell on my corals and rocks
So with time, I now have algae all over the rocks and brown algae on the sand (some places) but it seems to be brown and light maroon. There are even bubbles everywhere. I can't tell if it is Cyano or Dinos or just plain algae. I target fed my corals with Reef Roids and that made the algae worse the next day. If I lightly scrap the algae it flakes off in chunks and bubble goes to the surface. Likely will clean a rock at a time as I do weekly changes.
Today I checked my params and was surprised that my Phosphate (Hanna checked) was 0.006ppm and Nitrates almost 0!! Maybe they are low as the algae is consuming it. I had bought some Phosguard and Brightwel MicroBact 7 to help but may hold off since I have no nutrients.
Suprisingly my corals are doing okay, growing slowly but feel algae is bothering them. My Sunny D's are slightly open and stretching. My Xenia is vanishing (I can't believe my tank is killing Xenia

) My bubble tips (2) are well and split during this time so now have 4. Each one seems healthy and moving around the tank trying to find the home where they like (separate issue).
Any thoughts or help? I may stop Vibrant for now and switch to MicroBat7 tomorrow during my water change. I may also feed more but I need to claw back the algae growth. None of my CUC seems interested to eat this algae.
Looks like in the last picture my lone red hermit crab is saying save me
