Oh.. ok, will add then

I agree with burr that you shouldn't ignore PO4. I would start with the recommended amounts and adjust as needed.

If you will have such a high bio-load, it would be a wise choice to do frequent water changes. If you do this then EI would be a better dosing method in my opinion.
Well then is it ok to add both at the same time?

Not at all. The choice should be based on water change frequencies and/or the amount of plant growth you expect. PPS requires less maintenance but less growth. EI requires water changes and typically more trimming due to more growth.

The doses listed in this thread are for EI. If you want to understand more about this method read this, https://www.plantedtank.net/forums/11...explained.html

Kool thread, and great info. Well i selected this method coz i can only do wc once in a month or max once in 3 weeks. also since i have water issue, i can only do 50% wc, everytime i do more than that, fishes die. I dont have a space to keep 80g of water and let it stay for 24hrs thwn add to tanks. I do direct tap water into the tank and use seachem safe, since then iv never had any fish loss. So please tell me when n howmuch to dose. Since for this method they say ro dose both every day, can i add npk before lights on and trace after lights are off for 6days a week and 1once a week add iron coz of somany red plants. Please suggest, im confused. We dont get many testkits here and most of them are old and expiered. Alao how to know what plant has what deficiency so i can add it extra. Thanks

This is typical PPS-Pro

Add the amounts listed in 500ml and dose 10ml once a day.

Macro Bottle
KNO3 32.61 gm (approximately 6 1/4 teaspoons)
KH2PO4 2.87 gm (approximately 1/2 teaspoons)
K2SO4 14.63 gm (approximately 2 1/4 teaspoons)

Micro Bottle
Plantex CSM+B 30.63 gm (approximately 7 1/8 teaspoons)
DTPA Fe (10%) 6 gm (approximately 1 1/2 teaspoons)

Micro and Macro are supposed to be dose on separate days.
Mon./Wed./Fri. Macro then Tue./Thur./Sat. for Micros as an example.

The shortest distance between any two points is a straight line...in the opposite direction...

Sorry, I forgot the Magnesium. Just add it to the macro bottle.

You're better off adding your iron to the micro bottle. Iron supplements do not remain available for the entire week. Better to add this on a regular basis.

You can dose macro and micro on the same day. You just have to let one mix well before adding the next.

Ok, so since iv already made csmb, and iron seperately, so if im dosing 20ml iron on weekend, ill dose 3ml everyday. Also csmb has some iron already. And instead of adding micro and macro together, ill add either 1 before lights and other after lights or incase i forget, ill add both after lights with 5mints interval... so finally am i correct??

My statement was a reference to the usually preset instructions given/w EI.
Given the Zorfox's credibility in such matters I'd not hesitate to follow
his "suggestion" before any from another source.

Been meaning to ask this question for awhile and since getting some nice new plants from burr740 I figured it is about time.
On my 75 gallon tank I have been using the PPS-Pro method. Originally I was dosing exactly as listed on the bottles as received from GLA. After battling with GSA for awhile I was told that keeping the phosphate level around 5ppm would help. Well, I was at 1.5 to 2. I have since modified the PPS-Pro as listed below and my GSA has reduced significantly and the API phosphate test is running around 5ppm now.

Now for the big question (sorry, I can tend to ramble).
Should I increase my K2SO4 mix from 29 grams / 500ml to 52 grams?
I ask this because I have been playing around with Zorfox's Windows based calculator and it seems he knows his $#!^ so to speak and I don't.
The spreadsheet below is a summary of what I know on the macro side
The pic is, well, what it is :-)

If you are dosing KNO3, then no.

The PPS-pro dose of KNO3 adds 0.6ppm of K. PPS-pro calls for 1.33ppm of K.

You're 29grams K2SO4 in solution is adding 0.75ppm K. So combined you reach your target of 1.33ppm K.

However, KH2PO4 also adds K. With standard PPS-pro dosing of KH2PO4 you can neglect it's contribution to K since it's minimal. But since your boosting phosphate to reach 5ppm, this will be adding significant amounts of K. A 2ppm dose of KH2PO4 adds 0.8ppm K.

TLDR: No, stick to your current solution of K, and don't add any K when adding lots of P.

edit: Just noticed your current KH2PO4 dosing. Just stick to your current solution of K2SO4 and dose as per recommendation.

Well you can always try it and see how it goes, nothing wrong with that. But it sounds to me like you've been reading some out-dated pps information from back when phosphates were still considered the big bad guy as far as algae.

That has been dis-proven time and time again. Look no further than the 100s or 1000s of people on here's high tech tanks running EI levels or greater. Personally I keep mine in the 5 ppm range in order to stave off gsa.

But the point is, if you dont think the fish load will provide enough N, what makes you think it will provide enough P? Those are the two main nutrients fish poop provides, in addition to some traces. It will provide virtually zero K, because there's none to speak of in fish food.

@Immortal1

If you are shooting for exact ppsp levels, then it sounds like you have enough, as @Audionut pointed out.

K is one nutrient that is virtually impossible to overdose on. To me, a better question would be why not add more? Esp if your hygro or anything else is still showing pinholes.
