I use excel daily to recommended dose, very heavily planted, and a Finnex Planted Plus 30" (20gL). I'm probably not going to do EI as I don't like the waste of chems nor do I plan to have CO2.
I may get dry chems at some point but I have lots of Flourish products I want to use up first. In addition, the dry chems don't appear cheaper, you have to buy a scale, bottles, and then the tins of them, especially the upgrade products, don't seem that much cheaper than Seachem products.
I agree I have to size down doses if I am not doing CO2 injection or the overload method of EI. To me none of that matters, it just means a smaller daily dose. My goal is to provide nutrients daily in the correct correct amount for a daily dose. The part I don't understand is why 2ml Seachem Flourish dosed twice weekly @1ml would not cause algae but .3ml dosed every day would cause it. That's what Seachem appears to claim. Waiting on a response from them but thought someone here might know.
