Red cyno problem.....

[marine_freak]

I have a 75 gallon oceanic with some rocks with cyno red on them in mats...... This is a acro tank, very high flow, 2 400 watt radium halides....... 8ft mtc protien skimmer.... and uv sterilizer. How can the cyno live???? Water perameters good...0 nitrates, amonia, etc. use RO water... I am completely baffled why I have this problem....any help???

Hi marine, I have a similar problem in a 58... will love to see some ideas.

I thought it was all about the flow. Put some pumps over the area.

Flow....I don't think is a problem...

Flow....I don't think is a problem...

I have a 70 rlt as a return pump....probably getting 900-1000 gallons an hour out of it since it is pumping from basement to first floor, I also have 3 1200 maxijets running in the 75..... that is a total of 1785 gallons of turn over!!!! or 23 times an hour.... I doubt seroiusly it is flow...anymore flow and i would blow the acros right off the rocks!!!!!!!!!!!!!!

Flow actually doesnt matter. The stuff will grow where it pleases. I have had it growing from the outputs of pumps, even.

What I've found works best is to leave the lights off for about 3-4 days. I actually just did just that last week. Worked great.
Dont worry about your corals. Storms occur in tropical areas for several days, they will be fine.

what if you have clams in your tank?.

Do a search for maracyn. Worked great for me after exhausting all other methods.
