Ferts.

I got mine from Rex Grigg Here: http://www.rexgrigg.com/

He's a little rough around edgees for most people.

He is very direct and to the point and pulls no punches. Once you contact him you see what I mean but the prices are good. For it's all about the money.

Best wishes,
Wes
 
Mgamer has the best prices as far as I know. Plus, he's a fairly active member here so not hard to contact.

I ordered mine from Rex Grigg at first but there are less expensive places. Most people use aquariumfertilizer then.

I would start off with...

KNO3
KH2PO4
K2SO4 (might not be necessary depending on desired K level)
Plantex CSM+B
 
Check out the sticky in this subforum for EI dosing instructions, there lots of other good info there too.
 
Aquariumfertilizer.com is a great place to buy ferts. They have anything and everything, and always ship very quickly, a lot of times same day but never later than the next day.


yup. that's where i buy from and will from now on.

here is the thread you need to read about ei, straight from the man

you probably dont need k2so4. most people dont. i dont have a problem in any of my tanks except for one that has hygro corymbosa compact in it. that stuff sucks it right up and shows k def very quickly

what are you using right now? a complete list would be best.

anyways for a first purchase kh2po4, k2so4 (although may not be necessary) kno3 and plantex. if you're amending your water any other way you'll want one or 2 other things.
