cyano?
What colors can cyano be? i had a purple color cyano attack about 6 weeks ago and it went away, but then after a week or two a brown cyano came . And the new brown junk seems to be very stubborn to get rid of. Should I put a bag of carbon in the sump where the water falls onto the filter media? I would assume I have a phosphate problem...
thanks. |

Increase the flow in the areas that the cyno is infecting, also if you continually remove the cyno, the other algaies will populate more and starve the cyno out. I would definatly increase flow, remove as much nitrates as i could, and physically remove the cyno. are you using RO water?

suck out as much of the cyano as possible, then leave the lights off for a day.

i have my flow at close to 12x. is that enough? i move the head so i dont have dead spots. it grows all over the bottom. it seems to go away at night, by hourr 2 of the lights on the next day it is coming back with a vengence. I use RO water i buy from the LFS to top off. i add kalkwasser mix to it to keep the calcium up to about 430. i run a skimmer 24x7. do water changes 10% every 2 weeks. does RO water have phosphates?

Back in the day when i had cyno problems, i blamed it on lack of flow in the area it was growing in. high nutrients, low flow, hi nitrates are all causes of cyno. What is your PH and ALK?

ph is about 8.1 calcium is about 430. but havent measured in a few days. ok, i just moved the flow from the powerhead to blow on the bottom w/o blowing the sand all over too bad.

I have the same problem. I have a pair of tunzes that creat tons of flow, but back in the back of the aquarium where flow doesnt reach, i get little patches of cyno over time. If i turn my powerheads up to high, i have a dust storm, if there to low, then things stagnate in the dead zones. I have gone to great lengths to make my tank as nutrient free as possible, and re arrange the rock to inhibit good flow, since then, i have been cyno free. Good luck!
With you calcium that high, your alk might be a little low, but your PH is holding pretty good, but low Alk numbers in my tank always equaled some form of algae. Check that param too.
