[supernareg]

for the past 2 weeks, i been doing 5 gallon water changes on my 30 gallon display (with 10 gal sump) and nothing affects my cyano... just recently it started about 2 weeks ago, still up today, i siphon'd most of it out, and it came back the next day. its ****ing me off. i feed my fish 2-3 times a week now before it was once every other day. i have 2 false percs, 1 yellow wrasse, 1 cleaner shrimp and about 6 hermits and 3 snails. i have a euroreef 5-3 skimmer in sump, temp's at 81-82 never below 80, never higher than 82. 150watt 20k MH, 2 55watt actinics. MH on for 10hrs, PC on for 12 hours. 6 stalks of xenia and a couple batches of GSP, zoos, candycane, and shrooms. whats causing this? how can i stop it? oh, tank is about 6 months old.

whats causing this stupid problem? i have the saaaaaaaaaame problem in my 12 gal aquapod with 1 seahorse and 1 cleaner shrimp in there.

Tuen off your lights for 48 continous hours, then come back and thank me.

Problem is caused by excessive nutrients in the system.

It is aided by light bulbs that have aged and shifted spectrums, low 02 levels, higher temps, dead spots in the rock work, and long photoperiods.

The period with no light will solve the symptom, the problem is for you to figure out.

I have heard of a product called something like "chemi-clean" it is supposed to get rid of cyano, but as said above, the problem is something in your tank.

Cyano is also a "new tank" problem, aided by all of the above.

Try chemi-clean, it won't hurt anything in your tank and will get rid of the problem temporarily, unless you fix what is causing the problem in the first place. As stated above, usually lighting and overfeeding are the main causes.
