lindsay,
I would like to know the initial results of your use for a fish only system. I want to see if the product can work in an enviroment with high nitrates & phosphates such as a fish only system. Currently using a lot of GFO & a large sulfur denitrator and my No3 & Po4 is not where I would like it to be.
Have only been running the pellets for a short time so cant say how well they will perform,but i am keeping a record so i will add the results at a later date.
