Anybody know which specific PO4 is in Brightwell Neophos?

[TWYOUNG]

Yes, just look for food grade sodium phosphate of some form.

Would this be appropriate and do you know how I would mix and calculate the dose? Thanks so much!

 

[TWYOUNG]

I do not think it will dissolve well into a dosing solution, nor in the aquarium. Calcium phosphate is too insoluble.

Sorry, I'd typed SODIUM phosphate into my search and didn't realize that was Calcium. Is this more what I'm looking for? It seems from what you've said it doesn't matter if it's mono, bi, or trivalent?

Both of those products are fine. Dose is a little different.

Will it come with instructions to mix to a certain concentration? Will I then need to figure out how much of that would be needed for each 0.01 ppm increase in my 150gal system?

No, it will not come with any directions, but once you pick one, we are happen to run some calculations.

As a general guide, which it typically more than adequate due to the fact that you will never get exactly what you dose to remain in the water due to bindimg to rock and sand, use this calculator and the entry for phosphate by potassium phosphate. You will need to do a lot of trial and error dosing to figure out an optimal dose. I'd start at 0.03 ppm per day for a bit.

Will this work?
