Hi guys ! Nice to see you馃榿

I had some problems and really need ur help.

I used EI before but it seems not work for me so I decide to try with PPS Pro. I have some questions

1/I change my water and start dosing. The problem is after change water my tank TDS is immediately higher than tap TDS over 100ppm ( I use TDS-3 test) ( 135 ppm compair to 40ppm ).
I read PPs pro menthod and recognize I need to change water if tank TDS = Tap TDS + 100ppm. Am I right ? so what happen to my tank ? and What should I do in this situation ?
2/ I use the calculator on rottalabutterfly website to calculate the recipe. Is that oki ?
3/ How much FE should I dose daily ? I cant buy CSM mix so I get a mix micro from my local supply which have 0.07ppm FE for 1 dose.

Actually, I cant find any inf about it so I have only way is asking u 馃槄
Hope u can help me with this one.
Thank you for help.
Ps: I am so sorry if my language is confused 馃榿

Are you using co2?
I don鈥檛 make it complicated. I change the water (50-60%) every week. I only add a little potassium, maybe 1ppm, and very little micros CSM+b everyday Because micros oxidize quickly. Fish food is enough for N+P for my tank. The water changes bring Ca+Mg ever week.
Find what works for you. It shouldn鈥檛 be complicated. Root tabs for rooted plants too.

I have Co2 and highlight. All fers ready to go 馃ぃ but I confuse about my TDS. I use EI for this tank before but recently I wanna try PPS PRO.
Btw thank you so much 馃榿

Huynhhung please provide use some information of your water source such as GH, KH, PH. And if possible provide use a link to the water quality report many utilities provide on line. With that information we might be able to figure out what is not working for you.

I also use the calculator on rottalabutterfly website and I encourage you to keep using it.

Most of the ingredients in CSM+B are stable and don't oxidize quickly. The only ingredient that oxidizes is Fe EDTA. It oxidizes if the PH exceeds 6.5. Most tap water has a higher PH. Also When Fe EDTA breaks down it reacts with phosphate making insoluble and therefor unavailable for plants.FE DTPA is a better choice since it is stable up to a pH of 7.5 and will not cause a phosphate deficiency. I dose my tank with Fe DTPA to 0.05ppm once a week.

However that is not the only other issue with this product. It is deficient in zinc and boron. The typical aquarium needs about 0.010 ppm of zinc. CSM+B provides about0.091 ppm. Simply not enough.

And lastly CSM+B has no nickel in it. Granted most tanks only need 0.001ppm of nickel but not everyone has tap water with enough enough nickel.

I tried CSM+B in my tank filled with RO water and a PH of 7 and I got zero growth in my plants. It was a complete failure. Most other commercial micro fertilizers are even worse.

What didn鈥檛 work when you dose EI?
it is likely Huynhhung doesn't know because EI also has it's problems. The original EI guidelines contained no remanded dosing guidelines for Calcium, magnesium, sulfur and chlorine. These are all macro nutrients plants need. that plants need and the EI guidelines simply didn't mention them. Now granted most tap water has some calcium, magnesiu, sulfur, and chlorin. But some tap water doesn't. Many countries such as Singapore rely on RO water and many people have RO systems installed at home.

What kind of potassium you add ? P.nitart?,p.phospat?Thanks,
