Have trouble with hammers

Also I agree with high nutrients can cause great coral growth because I used to have it for the longest time, phosphates were at ~2 ppm and nitrates ~30 ppm. I was able to fix the phosphate problem because it was my Rodi system so I basically had to replace all the components of it to fix it. So now I have low nutrients, which is not what I was aiming for.

Ok so it seems as if neither of my bottles say that. For the phosphate instructions, it says apply neophos as directed below to attain a minimum phosphate concentration of ~0.02 ppm. DO NOT EXCEED 0.04 PPM! Multiply tank captaincy (33 gal) by ppm increase by 3.785 = ml of product to use. It then goes on to stay stuff about reef biofuel and how to use it. For nitrate bottle, it says apply neonitro as directed below to attain an ultimate nitrate concentration of ~3 ppm, do not increase more than .5 ppm per day. Multiply tank capacity by desired increase by .1261 = ml added. It then does on to talk about reef biofuel and katalyst

Interesting....I guess that's why they give that heads up on the web instructions.

Well, if you're at 0.0 ppm PO4 and you're aiming for 0.10 ppm, then I guess the math is 33 * 0.1 * 3.785 = 12.49 mL....round up to 13 (or 15 if you're doing capfuls....one cap often equals 5mL.)

If you're starting from 0 ppm NO4 then I guess it's 33 * 5 * .1261 = 20.8 mL....round up to 21 (or up to 25 if you're doing capfuls.)

Also interesting. If you measure PO4 in your untreated tap water (after letting it run several minute) what do you get?

Currently I get ~0-.5 ppm, I haven’t tested it in a while as my numbers have been low, so I haven’t bothered with it. Also, is there a different dosage if you have more than 0. It is likely 0 ppm, because whenever I got the problem fixed, I tested maybe a week after it was fixed and haven’t tested since then, but as the numbers have been getting lower, it is likely 0

They are using that baseline since it's intended for "UNLS" maintenance where you are supposed to be at/near 0.0 all the time.

I think you probably phrased the equations correctly in your previous post where I ran some sample calculations.

You just may need to realize that you aren't adding very much N or P in either case, and when you are starting from zero, the things that were starving will SUCK THAT N and P UP QUICKLY.

Try testing again about an hour after you dose....see how much is left. You might already have to dose again. I would do this at least once just to see what you get, even if you can't do it every time. (Usually one double dose is enough to tame demand a bit.)

OR....there's also nothing wrong with dosing to a higher target if you can only test once a week.....If that's going to be the case here, I'd say dose up to 0.25 ppm PO4 and 15 ppm NO3 and see how that goes. See what's left in a week.
