maybe $10? Takes a few days, followed by a decent water change and a bag of carbon. Tilt the lid of your skimmer sideways, it will foam like crazy. This time next week, you'll be mad you didn't do this first

I had cyno, but I went the slow natural route. Used a turkey baster to get the worst off rocks and sand once a week. Dosed a bit more with microbacter and 6 months down the line it is gone.

IMO Cyno is natures way of solving an issue, granted we don't like it, but its still doing something useful. And unless the root cause is fixed it will eventually be back as the treatments out there only solve the symptoms not the cause.

Chemilclean also depletes oxygen levels so if you have a lot of fish you might want to add airstones as an added safety net.

Chemi Clean is awesome but just a word of warning. The directions have you turn off your skimmer and filter to use it. I had a 55 gallon with 5 fish in it and after turning off my skimmer and canister filter and just having one circulation pump I lost 4 of my 5 fish over night. At first I thought it was because of the chemi clean but now thinking it may have been due to a quick drop in oxygen? Just heads up if you don't have a sump or really good oxygen exchange, you may want to get an air stone or something.

The O2 thing is a concern, which is why I suggested just tilting the skimmer cup, keeps it foaming, but cup is by-passed and it just flows back into sump. Assuming it's an in sump skimmer. If not, do not do this

picked up some Chemi-clean, but going to try my current method first for a couple of days. If I can kill the cyano off, I have some increased nutrient export that I will use called Nitroguard which should help with the issue from reappearing.

So here is the plan:

24 more hours of lights out
25% water change
filter sock change
add Purigen for Nitrate reduction (anyone use this?)
add more MB7
slow ramp up of lights
cross my fingers while I take a 5 day vacation to London
start Nitroguard in about a week...it is in transit from Montreal

If the cyno is there when I return...nuke it with Chemi-clean!
if it still survives...move on to gold fish

I had cyano when I had zero nitrates. Low flow seemed to contribute as well. Higher nitrates and better flow improved things.

The directions on my box of Chemiclean state "Continue using protein skimmer, although skimmer may require adjustment to prevent excessive overflow." The only thing it says to stop using for 48 hours is UV sterilizer, ozonizer, chemipure and carbon.

I only had to use it once in my current tank just after I set it up and have never seen it since. No issues for my tank inhabitants.

my nitrates tested high about 30 mg/ml so that is probably the issue not lack of nitrates.

Chemi-clean will be my back up
