|   If I add that, I get cyano. Tried and failed.

|   I tried it also Brad. Never did anything I noticed. Will stick to Prodibio. Mind you not sure if it does anything either. Also starting to add a bit of vinegar, manually. Can't put it in my top off, as it pushes kalk.

|   Your top off has kalk? You could add vinegar to that directly, it increases saturation of kalk. If you needed it more saturated.  But vinegar is carbon dosing, so you did it, but stopped, but doing it again?

|   Biopellets work...unless you do something inherently wrong.    I use the Reef Dynamics biopellet reactors on client tanks.  They are excellent recirculating reactors.  I have one client tank that was at about 500 ppm nitrate when I added the biopellet reactor a few months ago, and it`s now down to about 150 ppm.  That is significantly significant.  |
