Where do I go from here

[Lynden-Jeff]

Hi,

Looking for some input. Some back ground, I used to do reef keeping for about 5 years, 3 years ago when I go out of the hobby to pursue my current small business.

A customer just offered me his 90 gallon D.A.S setup, free, if I picked it up today. So I did lol. It was a FOWLR, fairly neglected as the LR was covered with a slimy cyano type algae, and I mean the entire tank was black. I packed up the LR with web newspaper and some water in rubbermaid garbage cans, and took about 50 gallons of water. I got the tank moved and the water in. Scrubbed the LR almost clean, looks alot better.

So I currently have a 90 gallon tank a little over half full with a powerhead and a heater. Whats the best way to top this up? I have an R.O unit which I have not ran in a while, but the membrain appears wet so I am going to use it. Should i gradually add the water or just take the chance and fill it up?

Also how can I prevent this cyano from coming back? Any good grazers specifcally?

Cheers
Jeff

1. no fish for at least minimum 3 weeks
2. protein skim non stop.
3. no lights for 4 days while you skim.
4. water test equipment.

will you buy new sand?

I'd go a step farther, Treat it as a new tank and let it "cycle" in the dark for a week or two to help get rid of the cyano. Watch for leaks and fill it up as you feel comfortable. Skim the snot out of it and do your tests. A phosban reactor will help get rid of phosphates which help feed cyano. Also lots of flow! I haven't had any critters that will eat cyano, just prevention is the best way. I also shut off my lights once a month for 3 days to control algae and cyano.
