Yeah, allegedly it reduces the growth of cyanobacter. One type of algae I wont miss.
lol Plan is to split 1 ampoule between the Opae tank, my now redone 30 litre cube and my wife's 60 litre once it's set up, so I'm not dosing too much at one time trying to use it up.
I've also ordered some macro algaes to try to acclimatise. Some chaeto and also some Caulerpa prolifera which I researched and read that it can do quite well in a brackish tank so long as you acclimatise it. Kind of hoping it works out and goes well and I end up with excess brackish grown macros to share. With my luck lately though it'll come through the door as green slime (already got a bottle of that for 2nd oldest daughter's bike.... lol).
Oh and yeah, I put some fish granules in right when I first set up as a source of nitrogenous wastes etc. If that doesn't work, I might put a tiny bit of biomature in there, that stuff usually kicks HARD. lol No diatoms in there yet either though, it's still pristine. lol The coral sand shines....
