Thank you. Thank you. Thank you, Raychel!
I would like to get two of the Potassium Nitrate at $5 each for $10. Thanks!

It looks like Planted Aquarium Fertilizer will offer a 10% discount to clubs which we will pass on to members. We are conducting this Group Buy in tandem with GWAPA which will hopefully help manage shipping costs as dry fertilizers weigh a lot.
Using dry fertilizers is about 20-25% the cost of purchasing bottles of fertilizers so the savings are substantial indeed.
For those who might be interested but aren't sure how they would use the dry fertilizers, the Planted Aquarium website offers many useful articles on dosing. Nick Kinser made me aware of Ghazanfar Ghori's formula as published on the GWAPA forum under the topic Simple Macro Mix (http://gwapa.org/forum/viewtopic.php?f=7&t=6300&start=40&hilit=stock+solution).
Here it is for those who haven't registered to use the GWAPA forum (if you haven't, I highly recommend it as a treasure trove of information).
To make 250 ml of Stock Solution:
Stock Solution A
250 ml H2O
15 g KNO3
5 g 5Ca(NO3)2.NH4NO3.10H2O (sold as Calcium Nitrate)
Stock Solution B
250 ml H2O
3 g MgSO4.7H2O
2 g KH2PO4
14 g K2SO4
Dissolve the salts in half to two-thirds the amount of water, shake well, and when dissolved top up with water to make the total volume of solution.
Dose 1 ml stock solution per gallon of tank for high-tech tanks, half that for low-tech tanks. When dosing, don't mix the two stock solutions -- add them separately to avoid having certain chemicals bind.
Graduated dispensing bottles are handy for dosing tanks.
All of the ingredients are available for purchase in the Group Buy.
I also really like the root zone tabs and Nutritrace CSM + Boron. I would be ordering a lot in this Group Buy if I hadn't just placed an order with them back in December. I probably have a 2-3 year supply of dry ferts on hand now.
I'd like 2 orders of "Substrate Root Zone Tabs" ($10 total)
