Yup, I saw that, but you didn't name it, or say how you are using it. That's what I was looking for. I didn't want to say too much in case you were using a different one, which I can't really speak to.

First, MB7 will NOT stop a full blown cyano outbreak, or at least not quickly without a lot of heavy dosing. That's why you have to use Chemiclean to wipe it out (be sure to follow the directions exactly for dosage and duration). So really no point in wasting MB7 at this stage.

But once your cyano has been killed off by the Chemiclean and your tank has stabilized, then start your MB7 dosing (heavy schedule for 1st 2 weeks). It takes that long for the bacteria to get fully seeded. You should see the results in your tank as well, with cleaner water and less mulm and smoother bio pellet tumbling in you reactor.

Then reduce the dosage over a couple days to the low dosage schedule. Keep an eye out to see if the cyano shows any signs of returning. If it does, immediately ramp up to the heavy dosing schedule for a week. In that time, it should be beat back again, and you can go back to the low dosage schedule.

I used to have major cyano problems. But the last time I had to use Chemiclean was over 2 years ago now, and have never had a major cyano outbreak since. And this was despite some other problem episodes with phosphates and algae. I have seen it start to appear a couple times in the past after I was away for a while and unable to dose the MB7 (I manually dose only). But when I applied the heavy dose regime, it would promptly disappear, and I would go back to the low dosage schedule.

In fact, I actually can't remember anymore the last time I saw any cyano start up again, has to be more than a year now. And I now only dose 1/2 the low dosage amount spread over about twice a week. The bacteria seems to be well established, as I haven't even had to clean my bio pellet reactor since last Nov (yup, over a year now), and not had to fill it since then either (down to only a 1/4 cup or so of pellets left). And my nitrates have shown zero for about that same length of time.

So this is why I am so convinced that MB7 works (as a preventative). Also, am not sure phosphates are the biggest culprit either. I say that because this summer and a for a few months, I had high phosphates when I combined another tank into a single sump. That did cause other problems (like algae), but I never saw any cyano. If anything, I think nitrates have a greater effect. I believe MB7 makes your bio pellet reactor more effective (able to consume more bio pellets) which then does a better job of reducing/eliminating nitrates. I had a huge nitrate problem before I started bio pellets and MB7. And have not seen any nitrates register on my tests of over a year now, too. So I don't think all this is coincidental.

Oh, and I was beating my head, because of your rehash (which I have seen over and over) about your theory of cyano, with phosphates, etc. And nothing, or almost nothing about how MB7 (and perhaps some other bacterial supplements) are used to out compete cyano. So to me, it still looked like you were on the wrong track. Sorry, if I over reacted. But I was trying to get your attention. And hopefully I did now.
