(just before you feel like pulling your hair out).

It will not release the nutrients back into your system it just breaks it down so it can be pulled by the skimmer as dead waste.

I've used chemi-clean in tanks up to 2500 gallons multiple times, and never once has a tank crashed......

No screwing around, 100% recommend chemi-clean; all of the site sponsors carry it, do yourself a favour ( OP ) and save yourself the time; try it out.

no because there is no need to do water changes if a person has other methods of nutrient export.

i dont have a single patch of hair algae or any other kind of algae in my tank

perhaps you have no algae because the cyano from hell is consuming all the nutrients that arent being exported......the solution to pollution is dilution and no W/Cs = no dilution.....

ok but i've had cyano for a month...... not for the last 14 months i've had my tank setup

If orp drops below 350 I'm turning the skimmer back on.

It's at 391 now. Usually hangs around 400-420

My tank is 4 months old, had no other algae problems except had a bad case of cyano. Its a 10g nano and cyano was covering everything. Here's how I got rid of it; weekly 2.5g water changes and sucked up as much of it as I could. The water changes worked and its all gone.

You ask for advice as long as its what you want to hear. Do some water changes I bet your cyano goes away.

I maintain about 50 tanks in Calgary and tend to only get cyano in tanks with too low flow, tanks that have had persistent low kh, and tanks that dont get enough water changes. Water changes and increased flow have solved the problem Every time. And yes, it's at about the 8-14 month mark when you tend to see this problem
Build up.

Do you clean your gravel?

No I ask for advice and you suggested things I had already done. I vacuumed the gravel 5 times now and it always comes back 2-3 days later.

I only have 1-1.5 inches of sand anyway.

Since the cyano started I have done water changes with no improvement.

I've got alternate methods of nutrient reduction, which is why I don't do frequent water changes. I dose alk, calc, mag, strontium and iodine.
