Dosing a new tank with Aquasoil...

[Tug]

Hi,
If I might, EI would provide three doses/week. Each dose is meant to provide at least 7.5ppm for both NO3 & K to the water column. Here is a link that might further explain what I am trying to say.

Unless you are getting a large amount of N and P from fish waste, there's no need to add extra K, if you use KNO3.
It gives about a 4X more ratio of K+ to N.
Adding K2SO4 will not hurt anything either.

I use it for GH booster mix, but I've not used it for several years without any issues.

Edit - In this case, it is the soil providing the extra N and P for the plants. So, adding some K (7.5ppm every other day) should help insure there are no problems with deficiencies associated with low K.


GH Boosters are suggested as an alternative to dosing just K2SO4 because GH Boosters contain mostly Potassium Sulfate but also provide Calcium and Magnesium - insuring all three of those nutrients are not depleted. What is best - depends on the tap water. As Tom points out, he has not used GH Boosters for several years without any issues.

Thanks Tug, for some reason I couldn't figure out if the dosage was 7.5ppm's per dose or the levels accumulated over the week. No worries for me then.

My tap has adequate levels of Ca and Mg, so as long as I stay on top of water changes there should not be an issue without the GH booster. I have some in case I suspect some problems.
