How do you dose Dry Ferts?

I've been trying to dose KNO3 and K2SO4 in both of my 29gallon tanks. I made a solution in water that, when adding 1 milliliter, would raise the potassium by 1 ppm and the nitrate by 0.5 ppm. Unfortunately there is definitely NOT 100% dissolution (is that the right word?) and there are many "floaties" in the mixture. Just wondering if this is typical, or if people typically just measure thier 1/4 teaspoons or whatever and add it dry? Please help me out, my algae needs to die!

EDIT: is it true that micros should NOT be mixed in and dosed with macros?

water can only disolve so much into a solution. My suggestion is using less dry ferts to make the solution where maybe you have to add 5ml to raise 1ppm.

Or just disolve what you need to hit your target and add that amount into the tank.

oh yeah don't mix, dose macro and micro on alternate days.

Personally I measure what i need disolve into a picture of water and dump it all in at waterchange.

So you only dose once per week? Micros and macros?

midweek I will redose 1/2 the orgional that i do durring waterchange. It's easy, not as scientific as what most people will do, but it works great for me.

For my 29g I just take 1/4 teaspoon of KNO3 (tap water is already high), add some water into a 250 ml plastic bottle and shake it up and pour it in.

I also add about 1/4 tea of K2SO4 and do the same.

I tried the stock solution method and grew tired of trying to measure exact levels...and there was the issue of supersaturation points inside the bottles (the undissolved crystals).

Re-boot!

Ha! this is the record fastest advice ever!!! thanks guys.
Dissedent, I am like you in that I won't be dosing something every day. once/twice a week is plenty for me, and I think the types of plants I am interested in will thrive.
Georgiadawgger, sounds like you already ran into this problem with your 29g! I will likely be approaching it likewise, just mix it up in a seperate container every time I dose. This is a bit more hassle, but if it's only once a week then no worries

I hate to bring this up due to the high amount of controversy it has caused...

It's normal for there to be some insoluable matter in agricultural grade chemicals. It shouldn't harm anything.

That is true, I'll have some undesolved in the container I use, I'll just add more water and dump the remainder in.

BTW Hot water will hold more (disolve more) than cold water, think of making jello its the same concept.

use chucks planted aquarium calculator, i am new at this and it helped me out a bunch thanks to dissident, it tells you how much of the dry fert you can dissolve in a set amount of water and then how much of that solution you need to add to raise your ppm.

Yes I have been following chuck's calculator, but I'm trying to work out a system that is EASIEST. I would like to make a solution that is easy to dose, but it seems that it is not possible due to saturation levels of the ferts
I do understand that ag-grade ferts have some impurities, but my "chunks" had better be more that just impurities because there is a lot of them!

Personally making b unch of solutions takes more time and meaureing IME. First you have to get the right solution mix then measure that for the tank. I always found it easier to weigh out what i need and dump it in when I do my PWC. That way I dont have to calculate how much of the solution I need (if i test the water once a month), i just use 2g phosphate or 1g Fe... besides i don't have anything that meaures ml that well anyomre .
Whatever you get into the practice of using and whatever works best for you do it everyone does something a little different

BTW Chuck's calc is a little off for target levels.
CO2 30-40ppm
PO4 3-4ppm
NO3 15-20ppm
