Help dosing dry ferts

How to dose dry ferts.

My dry ferts will be here in a few days and I"m trying to decide what to do. I like the PPS method best but I would like to control the KNO3 & KH2PO4 a little better. ((Other tank ifno. is below.))

Will this work?

Thanks!!!

Macros
In 1 liter bottle:
59 grams K2SO4 (Potassium Sulfate)
41 grams MgSO4 (Magnesium Sulfate)
Fill with distilled water and shake well. Let sit overnight.
Dose 1ml per 10 gallons per day

Dose KNO3 & KH2PO4 according to testing.

Micros
In 1 liter bottle:
80 grams of CSM+B
Fill with distilled water and shake well. Let sit overnight.
Dose 1ml per 10 gallons per day

-------------------------------------------------------------------------------

10 Gallon Tank
6.7 wpg - (1x15watt T-8 & 2x26watt Spiral CF's )I know it's probably not actually 6.7 wpg)
DIY CO2
aqua-clear 30
heater
1 Bag of fluorite
NPK & Plantex (ordering on-line)

Be sure to calibrate your nitrate and phosphate test kits regularly if you are going to depend on them to determine your fertilizing dosages. That means making standard solutions of water that contain known concentrations of nitrate and phosphate, and testing those with the test kit to verify that the kit readings mean what they say. If you don't do that you are just guessing at the dosing, and might as well dose per either EI or PPS-Pro.

Did you use Chuck's calc for those numbers ?

I just checked what you have there and I came up with completely different numbers.
I may be reading the calc wrong though since I'm just getting started myself with dry dosing But here's what I got...

using a 1 liter bottle (1000ml water)

59 grams of KS204
your 1 ml dosing would give you 0.7 ppm. If you dose 3x week that gives you
2.1 total for the week. (your target should be 20 ppm according to the calc)
You would have to dose 10 times that much to reach your target.
(.7 x 10 = 7) 3x week = 21 ppm


41 grams of MgS04
your 1 ml dosing would give you .11 ppm. dosing 3x week gives you .33 total for the week (again according to the calc you should target 5-10 ppm)
you would have to dose 16 ml to be at the low end of your target)
(.11 x 16= 1.76) 3x week = 5.28

Can someone correct me if I'm interpreting this wrong but i think you dosing would be way too low.

You might want to use this method for your calculations, 7Matt7. My data is based on the recommended solution.

From: http://www.aquaticplantcentral.com/f...tml#post296688

PPS-Pro calculations
I used 37850 L for my water volume and the mix amounts in grams from the directions. I used the fertilator for my calculations:
Macro Solution
In 1 liter bottle:
59 grams K2SO4 (Potassium Sulfate)
65 grams KNO3 (Potassium Nitrate)
6 grams KH2PO4 (Mono Potassium Phosphate)
41 grams MgSO4 (Magnesium Sulfate)
Fill with distilled water and shake well. Let sit overnight.


This is what I got:
NO3 is dosed at 1.05 ppm per day
K is dosed at 1.41 ppm per day
PO4 is dosed at 0.11 ppm per day
Mg is dosed at 0.11 ppm per day

You wanna worry about fine tuning the nutrients like NO3, but wanna use cheapo DIY CO2 at high light?

I'd get my priorities straight before I'd worry about any of that.
Water changes and estimations on a 10 gal are very easy.
Also, you are going to be using a lot more CO2 and nutrients than pps will supply.

You might consider using 1/2 the light, use 2x 15W lights, get a better CO2 set up(DIY is okay, but if possible get gas tank, it's well worth it, or also use Excel in conjunction, or exclusively, a 10 gallon is economical) or make sure the CO2 brew is changed often and in good shape all the time.

This will get you much farther along than any tweaking of a few ppms

Less light + good adherence to CO2 = much easier to tweak and tell what is going on with nutrients.

10 Gallon tank= very easy to do water changes(like 5 minutes once a week tops), Small so Excel and most any chemical additive etc will be cheap/practical.

I'd spend the $ on a nice 15W light, some Excel and perhaps CO2 gas tank if possible(it's a fair amount).

Then you will have far more success. Nutrients are only maybe 10% of the issues with growth, most of it is light and CO2.

PO4 is dosed at 0.11 ppm per day
Mg is dosed at 0.11 ppm per day
To dose the ppm how much in ml do you add to your tank daily?

When following PPS-Pro guidelines one doses 1ml per 10 gallons daily.

Many people report getting GSA when using PPS-Pro. You may want to add additional KH2PO4 if you do.

Thank you all for answering!!!

The reason I was going cheap on this "experiment" is that it was going to be a learning experience before I tackled my 75 gallon.

The 75 gallon tank that has been established for around 5 years and the nitrates are 40ppm even with 30% weekly water changes. And I was worried that the phosphates were pretty high too. (P test is on the way)

I wanted to dose potassium, magnesium, and trace without dosing nitrates and phosphates. Or at least dose the nitrates and phosphates separately if they start lacking.

After hearing that I guess what I'll do is just save up for the press. co2 and just start with the 75 gallon. Can someone give me an outline to go by get the 75 off to a good start? What do you suggest I do about the nitrates and phosphates all ready in the tank?? (specs below)

I'm still curious... can't you just mix each macro up separately? I mean.. If you wanted to?

Thanks so much!!!
