Thanks for sharing that explanation Darren, that makes perfect sense now. I'm pretty sure it has made a difference, so Mg must have been the issue.

Morning Clive,
so according to the nutrient calc for 100L i should be dosing the following
1.5g KNO3 (1/4 tsp)
0.58g KH2PO4 (1/8 tsp) (or half of a 1/4 tsp as i dont have a 1/8 measuring spoon)
3.7g MgSO4 (3/4 tsp)
im going more on weight rather than tsp's. i have small scale digital scales...
And constipation. Lol
Ceg, I'll post Tomorrow with the Grams per dose (dry dosing) of each. It's a 120L tank I think I worked it out based on 100L of water after displacement (ish).

i think im dosing standard EI.
KNO3 just over 1/4 tsp 3x per week
KH2PO4 just under 1/4 tsp 3 x per week
trace on middle days
2 days rest
water change on day one and start again...

growth seems good its just not as lush green as id like. we are only 2 weeks in so it might just be...
Hi,
Basically I want to increase the nitrate in the tank and am dosing EI KNO3 and KH2PO4
can I simply increase the KNO3 or should I also increase the KH2PO4 to keep the ratio of ferts the same?
ive got plenty of co2 in the tank and distribution/flow is fine, good growth but dwarf hairgrass...
Ok cheers, water here is very hard so that's probably the reason I didn't do it last time. I haven't run a proper planted tank for 8 years or so and have forgotten most of the detail behind ei etc..
im about to set up a new tank 120L "shallow" with high light and co2 injection. i wasnt going to go the EI route which i did on my last tanks years ago making up liquid mixes etc but ive changed my mind.
i will be dry dosing and have ordered KNO3, KH2PO4 and trace mix.
i havent used MgSO4...
