So currently im using seachem, Co2, K, N, P, and Fe, and ive been looking into start using dry ferts. I was looking at getting GLA ferts. Read some stuff on line about them, didnt quite understand what i was reading so i was hoping someone who has used them before can help me
My main thing is what produccts should i buy to make sure i have the correct suppletnts for the plants?
Should i do it the same way i have been, during a water change and mix it in with the new water?
This link is a thread on the EI concept of fertilizing a planted tank and should answer the question of when you should dose.
How much should i get to last say 6 months for two tanks, 55, and 44 gallon
I buy my ferts a pound each at a time, I have a 40b (high tech) that gets dosed daily N,P,K on Mon, Wen, Fri, & Sun, then on Tue, Thur, Sat I dose CSM+B.
On my 29gal (low tech) that gets dosed N,P,K day of water change, and CSM+B the day after.
CSM+B has Fe in it, usually enough for most tanks unless you have some of the more demanding red types that need a tad more iron to become the vibrant plants we desire from such species.
A pound lasts me right at a year. I agree with the posters suggesting nilocg for a source for ferts, I've bought first from GLA, second from nilocg and will continue to buy from nilocg as long as he continues to sell.
Here is a couple of threads that have dosing recipes for different volume tanks.
First one is the one I refer to when I need to get my starting point on a tank.
This second link has more than recipes and briefly covers other issues like algae and lighting.
