Will 3/8 teaspoon of potassium nitrate and 1/16 teaspoon monopotassium phosphate dissolve in 2ml of water and 3ml of metricide 14? That would leave me with a nice 5ml dose every other day.

I doubt that will dissolve, if you tell me the tank size and what size container I can help you make a reasonably concentrated solution.

Looking for a 500ml container to dose a 37 gallon.

and while im here I have flourish trace, is it going to differ greatly from csm+b?

I used the recipes on your site - working great! Thank you.

Work computer won't load the site


Ill have a look when I get home.

He will give you the recipe, I just wanted to say thank you to nilocg. Sorry to hijack your thread.

Not an issue. Its why I love forums, you get information from the source!

Yes it will be quite a bit different. CSM+B will be closer to Flourish comp.

Bump: KNO3 67.123 gm approximately 13 teaspoons
KH2PO4 10.224 gm approximately 1 3/4 teaspoons
Plantex CSM+B 42.028 gm approximately 9 3/4 teaspoons

Add kno3 and kh2po4 into one 500ml bottle, CSM+B into another. Dose 10ml of each bottl3 3x per week on alternating days. 50% water change on day seven is suggested.

Perfect! I mixed her up earlier this morning and gave her a dose. Worked out quite well. I still wasn't sure it would all dissolve but it did. Thank you kind sir.


This solution should also work on my 37 gallon with a lighter plant load and less lighting.

You are welcome. Yes it will work fine on a tank with lower light, just dose 1/2-1/3 the amount.
