Unpleasant surprise

[DFD189]

Sprung up overnight.

What is going on? Cyno, algea, diatom or some other mutant life form?

A picture would be most helpful.

Yes, pic(s) please. Also, what inhabitants do you have in your tank, how long has it been running, etc.

We'll help you get back on track.

Pics are showing up on my end, I'll re-post.







80 Tank has been running since the beginning of July.

It has 10-12 Astria snails, 10-12 blue legged hermits, 3 peppermint shrimp, 1cleaner shrimp, 2 percula clowns, 2" hippo tang, and a large LTA. 3" sand bed and bout 60-70# of live rock with paly's, zoa's, leathers, polyps and xenia.

Run a wet/dry trickle filter, skimmer, and fluidized sand filter.

I dont see any pics still.

Did your sand bed get disturbed lately? Anything die recently in the tank? Both common causes of a cyno cycle.

Fixed?

I lost an emerald crab about a month and a half ago, (pretty sure he was on his last legs from the LFS I got him from) but it was taken out the day it died.

The sand bed hasn't been disturbed.

You have Cyano in your tank. PITA but fixable.

[Sir Patrick]

I see pics! Its cyno. Fairly common in a tank that age.

For sure- PITA!

I have had good results with maracyn (erythromyacin), to get rid of it.

Normally I would sugest getting to the root of the problem, but cyno is one of those things that the root is hard to find, if nonexistant to be proven yet. Thats why I turn to the maracyn for this particular issue.

[DFD189]

Will the maracyn effect the beneficial bacteria in the tank?
