Hi,
I just got my tank water tested at medical university laboratory and the result is :
Unfortunately, the analysis not including PO4 and K, so I still don't know the actual result in my tank. Please note that the Chloride is 78.1, is it too much? What is the safe level here? I know that Seachem Flourish contains 1.15% of Chloride but I think the reading is high enough. Will high Chloride stunt and/or toxic to plants?
To make the story short, it took me almost half year to realize that my Sera NO3 Test Kit was very very inaccurate, usually I dose the whole week and at the end of week I tested the NO3, PO4 and Fe residue and adjusted the dosage next week. Sera NO3 Test Kit gave me the reading of around 30-40ppm and the result from the lab is only 5ppm. Before I have my water tested, I dose KNO3 as much as 20ppm of that whole week and the residue was 5ppm but before the last week I used to dose from 5ppm to the most was 10ppm because every end of week the reading was very high 30-50ppm. This is my very big mistakes and costly experience to learn.
Frankly speaking, I'm adjusting the KNO3 dosage almost every week from my last first day setup until the past 2 weeks and that's why my plants is stunt now, apparently I gave them very low nitrate.

What deficiencies do you see from my plants? Do the plants will still be able to recover from a long stunted growth? Right now, I'm dosing 30ppm KNO3. I also noted from the result above that the Manganese is 0ppm but the Fe is 0.5ppm, what should I do? Adding too much micro nutrient will bring the Fe too high to compensate for the other low % of micro such as Manganese. I used to dose Seachem Flourish as micro 5ml 3 times a week (80x30x40cm tank) and the result above showed that I might have micro deficiencies too but from yesterday I replaced the Flourish with CSM+B Plantex 0.39gr every dose, knowing that it contains much more % of micros but less components compared to Flourish. What should I do to the micro def here?
Once again Mr. Tom was right about the lack of NO3 in my tank was the culprit BGA occurred. Please steer me back to the right track, Tom
. Thank you very much.
