Trident controlled dosing

[techhnyne]

it never seems to work for me as i am using settings outside the reccomended values. My tank naturally sways outside the ranges slightly after a few days so it is never working properly. Anyone know a way to extend the range and still have it work ? Its so annoying. I might switch to ghl if their controlled dosing works better

I had a similar problem. I just use the DOS as a regular doser and adjust as required manually.
