Yey! Mini M is a good nano size, I'm happy you received yours today
I bought the PPS-Pro package from green leaf aquariums that came with 2 bottles. I think there's two types of fertilize system that you can do which is PPS-Pro and EI. I think the only difference between them is that EI provides more than enough nutrients where you need to do a water change once a week to do a cycle again. N-P-K one day and Csm+B the other day. PPS-pro on the other hand, measures just the right amount of nutrients where the plant will use up all the nutrients before the next day. Meaning you dose both bottles on the same day just enough and you don't
have to do water change at the end of the week but I still recommend that you do. For this method you need a small scale that weighs in grams.
Bottle #1
K2SO4 – 29 grams
KNO3 – 33 grams
KH2PO4 – 3 grams
MgSO4 – 20 grams
Bottle#2
Plantex CSM+B – 40 grams
(The instructions doesn't say to do this but I also add about 100mL of excel to prevent this bottle from having algae which it tends to do over months)
The recommended dosing quantity is 1 mL of each bottle per every 10 gallons or 40 litres of aquarium water. Dose daily, prior to your aquarium lights turning on.Dosing examples:
5 gal / 20 litre –> 10 drops
10 gal / 40 litre –> 1 mL
50 gal / 200 litre –> 5 mL
100 gal / 400 litre –> 10 mL
The dosing examples is a guideline to where you should dose. In a small tank like mine, you should also take in consideration on how much plants, substrate, and rocks you have because they take up space in the tank. That's how I got 9 drops for me

trust me what I say 1 drop will make a difference lol the solution in the bottles are very concentrated. I played around with how many drops per day for months and found out 9 was perfect number for me.
