Yap. Hence the chance of feeding the wrong bacteria and have cyano bloom. But the cubes might have some other stuffs in it too because they seems to work extremely fast compared to pearls.

Should write them a letter and get to the bottom of this :)

Yea i heard they can reduce a fish only system of 100+ ppm nitrates to 0 in a month or 2

Yah that's kinda scary! Fishes be like "oyeee I can't poop any faster".

thanks for the input!

Hello

Out of curiosity what kind of skimmers and tank sizes do you all have here?

Hey boss

Myself I run a 42g system with a nac7 skimmer

130 rsm and a 65 gallon with eshops 100 skimmer.
Can someone enlighten/explain to me about the comments about cyano and the concern of feeding it if you run stuff like nitro guard?

I have 0 cyano or any aleage for that matter.

Well bio cubes are food source for bacteria. Generally, what you want is to feed the right bacteria (denitrifying) but occasionally, the wrong bacteria starts eating and cyano breaks loose. It helps to dose the right bacteria too (like MB7) so that the right bacteria can outrun the wrong bacteria with the food.
