Dry Rock and long-term bacterial bloom

[Skimmin]

So I figured I'll follow up with my last post. Since I last posted my tank started to cloud up a bit again. I have never used a uv lighr before but decided to give it a try. Its been four days and all I can say is WOW. My tank is crystal clear now and everythi g seems to be doing great. Even the algae blooms have receded. I was having to clean the green off my glass every day. Its now been two days and its still nice and clean. I think im going to start running uv as regular maintenance. Maybe for two weeks every six weeks or something like that. What a HUGE difference

One thing about UV sterilizers is that you do need to carefully clean the quartz sleeve every 3 months or so, especially if your dealing with a lot of bacteria. Use rubber gloves when you do as it's not good for them to get skin oils on them.

Cheers,

I'm glad the UV worked out for you!

I ran a 1 micron sediment filter (the kind you usually put in an RO filter) on a powerhead for a week. I also built a DIY in tank canister filter that attaches to a power head as well and ran filter floss and half a cup of carbon (still currently running). Ran the skimmer as wet as it would go. Also ran a filter sock on the sump. Increased my flow through my sump for more aeration, and to allow the skimmer to possibly process more tank water. Did a three day blackout with no lights.

No change. Still has that hazy look to it.

Fish seem fine. All the other coral frags I have seem to be doing ok, but my blue xenia frag that is just about a month old has in the last couple days almost entirely disappeared. I moved it to another small 20g I set up with a power filter in a last ditch effort to save it.

I think the UV may be the way to go... I don't see any other options.
