Where can I get a source of phosphate? I thought I had read somewhere that fleet enema [http://www.fruit-eze.com/brands/flee...ger_lemon.html] was a source for phosphate, but I'm not sure after looking at a bottle. It had monobasic sodium phosphate and dibasic sodium phosphate. I thought I had read somewhere that what I needed was potassium phosphate.

Should I forget about going this route and just order something?

Fleet Enema is an excellent source for a Phosphate suppliment. It is complete and easy to dose.........and inexpensive.
Just remember to go easy with dosing P. A level of .50 - to 1.0ppm is the range you need to stay in. I only dose when the level drops below .50ppm. And Fleet is what I use. Good stuff.

I think with the very small amounts of chemical that you use (a few drops) it doesn't matter if it is coming from sodium or mono potassium phosphate.

I am using from Wardley's sodium biphosphate Ph reducer, $1.57 from Big Al's. I use a "rice grain" at a time (no wonder people who mess with pH have such high phosphates, the directions say to start with a 1/4 teaspoon per 10 gallons!)

What does that mean? I just read another reference to that on the APD in reference to the Tom Barr method.

a rice grain is an unofficial measure of volume roughly equvalent to the volume occupied by a grain of rice.

Short grain or long grain? I prefer to make a stock solution for dosing phosphates.

Ok, I bought some Fleet Enema. I decided I needed to try and find out how much to dose and I figured I would start by measuring the phosphate level coming directly out of the bottle. The problem is that it didn't register a single thing on my test kit. I tried mixing up a little stock solution to see if maybe it was just overpowering my kit or something and it still didn't register anything.

I know the kit is good because I just used it over at my mother-in-law's house to try and help her determine her green water problems and my kit turned more purple than I have ever seen it before.

So is this phosphate in some form that can't be measured by my kit? If so, then how the heck do I know how much I need to add or maintain?

If you add enough it will register on your test kit. How large is your tank?
How heavily planted is it?
Initially I added 2 or 3 drops and tested for content. If, after an hour I got no reading, I added 2 more. At some point during this process you will get a reading. After getting a reading of .5 - 1.0 you wait to see how long it takes the plants to use it. You will soon get an idea of what your plants use in a given period of time.
It really depends on the plant load and types of plants, how large a dose should be and how long it will last.
If you are saying that you took a small amount of water and put X amount of drops of Fleet's Enema in it and got no reading there is something wrong with your test kit.
I have a 40 gallon, heavily planted tank. I can test and get no reading....add 7 drops directly to the tank and get just over .5ppm. In that tank it will be gone in 3 days and I'll re-dose. I also have a 55, not as heavily planted. I use 3 drops, twice a week in it to maintain .5ppm.
Very simple.....very easy.
