Cynao Problem

[Earp]

Cynao covers my rocks and is choking my corals (mostly softies). The tank has been up for over two years in its current location, and for the most part has been around since 2002.

I am wondering what can be done? Add more flow till the tanks practically a washing machine?

Tank specs: 90g display, 20g long sump, 55g fuge. CSS 220 Skimmer, 2x65 watt PCs and 2x54 watt SLS T5s on for 9hrs a day (too long?) The return is a mag 12 and I have a seio and 3 mj1200s in the tank for water movement.

The fish load is rather low, I think, a marine betta, fu-manchu lion, algae blenny, and a six-line.

So what can I do to stop the cyano problem?

sure, check out this thread--it deals with how to fight algae but many of the suggestions are suitable for cyano

talked to a LFS just the other day and he stated you could use Red Slime Control by Blue Vet. www.bluelifeusa.com I have never used it but he stated they use it in all their display tanks all the time and it does not hurt coral, fish, or anything. I am still a little cautious about it though. My problem was small and water changes along with removing the rock that I could and scrubbing it for once every couple of days did the trick. If you try the red slime he said to turn off the skimmer and use as directed one day wait one day then repeat a second day and it should all go away. After the second dosage make a 25% water change. If he was telling the truth and is using it on their display tasnks then you will have no problem with your corals or fish. Hope this helps.

I read a thread on this site where they turned off the lights on the display tank for a maxmium of three days. He stated it is safer than adding chemicals. You may consider this method first and it doesnot work you have a fall back using the above chemical.

Treatments like Red Slime and ChemiClean are both bandaid fixes. You'll still need to find the root of the problem, or the Cyano will come back.

I found that cutting back on my light cycle or a few days of darkness once a month is helpful with nuisance algae and diatoms. I'm not sure if it will help with Cyano (photosynthetic??), but it will not hurt to try.

I agree with you--that is why I suggested reading the above thread. You need to change your thinking from a cyano problem to a nitrate and phosphate problem then you can find out where you are importing them. Stop the import of cyano you stop the cyano
