I was actively into saltwater aquariums several years ago but lost interest due to losing all the fish and corals I had. I am wanting to get back into but want some advice before I do.
I have a 55 gallon all glass aquarium.
In sump skimmer
Corallife 9w UV
2 - 48" VHO
1 - 36" VHO
1 - 75w powecompact 10,000k sunlight
About 50lbs live rock left over from last run.
My tank has been sitting with water and the live rock in it with the lights off for about a year or more. I would add tap water to the tank just to keep it running. I decided to turn the lights back on and try it again. I have lots of brown hairy slime growing on the rocks. My guess is the phosphates from the tap water?
So what would be the best way to get this tank rolling again?
Thanks for any help.
