| | Re: glutaraldehyde instead of excel
This caught my eye because I have a tank that has just started devouring KNO3. I have been fighting a green threadlike algae, so I dose twice the recommended Excel. It is also lightly stocked (I think) and I recently let a small chain sword totally take over; I had assumed that those were the causes. Of course, this was with Excel. I am almost out and just received my Cidex 3.4% yesterday, getting up the nerve to try it out. The poster above said that Excel did not have this effect in tests, only glutaraldehyde did. Does that mean I could need to add even more KNO3? yikes.
