I did give the "blackout" a try for 2.5 days. When I removed the cardboard from around the tank, I was very pleased with the results. No slime anywhere!
However, within 2 days it was back, bigger than ever.
I don't think this is cyano, as it is very brown/gold color and the cyano I have seen is more a reddish color. Also, the cyano I have seen looks more like a dusting or thin layer....where this stuff is very thick, grows tons of bubbles, and will eventually pull off and float up in "sheets" of slime.
I plan to repeat the treatment in another 24 hours as directed, and then follow it up with another 40% water change. So far the stuff isn't taking over the rocks like it did before....but that may just be wishful thinking...
I have been under the impression that large water changes are better than smaller, more frequesnt ones are. Is this true? The logic goes:
If you have a count of 100 of X and do a 50% change you have a balance of 50 X left behind.
Yet if you have a count of 100 of X, and do a 10% change you have 90 X left, then do another 10% change you have 81 X, and another 10% leaves you with 72.9 X then another leaves you with 65.9 X then finally another gives you a balance of 59 X.
The math seems right....if you change the same amount of water (50%), you would be better off doing it in one change versus 5 10% changes.
Then again I could be all wrong......
