Yeah phosphates are less than .1ppm, have had very good luck with vodka carbon dosing up to this point. Just added the biopellet reactor to get off the daily dosing regime, so i can go camping and on vacation without worrying. Just added 21 fish in a month so a bloom was expected with the addition of another carbon source.
So it is an anti-bacterial? Thanks man that was exactly the answer i was looking for. I've worked too hard to get the bacteria populations to where they are now, and it seems this might throw that stability out of wack. I'll just stick to the old fashioned way of manual removal to get the trapped nutrients out and my carbon dosing and water changes

. May take a little more time but i feel a lot better about that than adding a chemical that will kill my precious bacteria. Quick fix does appeal to my lazy side though

Your phosphates are actually very high, and could be partly to blame for the bloom. You want to get them down to .03-.05. There could be something going on with your changing the carbon source too (ie maybe a temporary issue that will pass). I added a biopellet reactor for the same reason as you.
I've done a lot of things to my display that have impacted the bacterial filter and/or caused a recycle, so I've been aggressive versus conservative. Fortunately thought, I haven't killed any life for awhile

. I did take the risk/plunge with Chemiclean, I saw absolutely no impact to the nitrifying bacteria and/or cycle. You'll see lots of people on the forum have used this that are extremely conservative with what they put in their tank, and report the similar and very positive results. Generally it seems safe. But, you are taking a small gamble. That said, Cyano can have toxins, so choose your poison.
If you take the old fashion approach, you should recheck your water source as well. Some who fight cyano non-stop see that the water change actually causes heavy/new growth. Are you using tap, filtered, RO, or RO/DI water?
You probably know the other cyano fueling issues...lighting could be an issue, flow, etc...

The BIGGEST mistake I see when my customers use this produce is that they do not take into account water displacement of sand, rock, filter and etc. when dosing! This is a MUST when using this product and some of the problems mentioned may have been avoided. Although this product works well (if used as directed) it's a "band-aid" to the problem and not usually a fix. Also Banded Sleeper Gobies will usually eat cyanobacteria and reef safe. Again this is only a "fix" and not a cure.
Agree with Ron, and in fact I never ran a full dose on my calculated water volume (figuring what was displaced), just to be safe and err on the side of underdosing. You do not want to overdose.
Wow - Banded Sleeper Gobies? Amazing! Thanks for that tip, Ron.
