I'm a newbie setting up a 55 gallon aquarium. So far I have java fern and anubias in it, but I would like to order some more plants and fertilizer. It will be a low-light no CO2 tank, so I am thinking about using the fertilizing method here http://www.sudeepmandal.com/hobbies/...singfertilizer
. I would like to go with dry fertilizers as they seem more cost effective, but in the method above Seachem Equilibrium is used. The author mentions that you can use CSM+B instead of Equilibrium, but then you will need to add Calcium and Magnesium. I am wondering what dry fertilizers I should use for that, and how much should I dose?
The dosing is set for EI method which might be too much for a low tech tank.
If you are buying dry ferts then CSM+B is your trace and Barr's GH booster (@ aquarium fertilizers) will provide the Magnesium and Calcium.
So you need to buy:
Potassium Nitrate <-- Nitrogen(N)
Monopotassium Phosphate <-- Phosporus (P)
Potassium Sulfate <-- Potassium(K)
GH Boosters <-- Calcium + Magnesium
CSM+B <-- Iron and Trace
The dosing specified in that article is for EI dosing method which works best with good light + C02 injection. Without those 2 then you are going to be creating an algae farm. As mentioned in the article:
3) Very low fertilizer dosing, and only occasionally
The dry ferts can be used but I would suggest to get the complete water test kit and the Phosphate and GH test kit since it is very easy to over do the dry ferts.
Also the EI method is under the assumption you are going to do water changes on a regular basis which basically resets the nutrients in the tank on a weekly basis. If you have no plan on doing that then be prepared to figure out the right dosage for each fert.
