pre planning a dosing schedule

i am building a 20L with the intentions of a high tech scenario

doing the dsm and just got the hc "seeded" last night so i have at least a couple of weeks to pre-plan

im running a ray2 and have a substrate of eco complete of an inch of mgopm

i will be running pressurized co2 with the high lighting

my question, is this all the dosing that i will need, or at least a good place to start?

10- 20 Gallon Aquariums
+/- 1/8 tsp KN03 (N) 3x a week
+/- 1/32 tsp KH2P04 (P) 3x a week
+/- 1/32 tsp (2ml) Trace Elements 3x a week
50% weekly water change

secondly, where is a good place to order the kno3 and kh2po4?

The ferts listed seem adequate to me. A few words of caution however. Using dry fertilizers in such small quantities as 1/32 of a teaspoon leaves a very large margin for error. I would suggest mixing solutions to reduce that possibility. This calculator has a selection for mixing solutions. It reports weight to be added to your solution. If you don't have a scale you can convert the weights to teaspoons based on the weight of each product below.

KNO3, 1 teaspoon = 5,200mg (5.2G)
K2HPO4, 1 teaspoon = 5,800mg (5.8G)
Plantex CSM+B, 1 teaspoon = 4,300mg (4.3G)

I listed Plantex CSM+B since you are going to order dry fertilizers anyway. This would be a far cheaper solution in the future than using premixed traces. You may as well order some when you get the others since the shipping fees would most likely be higher than the product anyway. If you check out the for sale section here there are a few members that have quality dry ferts at a good price. Otherwise Green Leaf Aquariums is a good source IMO.

I would certainly measure the phosphates if using MGOPM. I tried it once and had very little success. The phosphate levels were of the charts. It eventually became anaerobic leading me to pull it all out. I am a firm believer in mineralizing the soil first now. Just my two cents on that product.

so the Plantex CSM+B would be the equivalent to something over the counter like flourish?

anyone else wanna weigh in on phosphates and mgopm in a high tech environment?

and thanks Zorfox!
