Should I get the Phosphurous Checker?

[lastlight]

i previously owned the regular tester and always got zero which i never believed. i certainly had algae which apparently IS possible with real zero readings lol. i now use the ULR and for a while i couldn't get back-to-back consistent readings.

now i do a few things that seemed to have made testing reliable and i now like the device:

- only use one of the glass containers. zero the unit and add reagent to same one. avoid differences in glass/scratches etc between containers.

- store ro/di in container between uses then rinse well before use

- made a decent paper funnel to ensure i can more accurately get all or almost all the reagent into the container

- always rotate the glass to the same orientation in the device

This thread is making me feel better about getting the phosphate checker vs phosphorus. As it is, I think there's too much number-chasing going on in this hobby.

if you like zero readings i highly recommend the phosphate checker =)

Agreed. As long as mine says 0, I don't worry about it.

If you're doing it right, a zero reading is good enough. Even if it's actually 0.04 (which is possible with a zero reading), that's low enough. If I knew for a fact it was 0.04, I wouldn't try to chase numbers and lower it to 0.03. And as long as you have fish and are feeding enough, there will always be enough trace phosphorus in the water for hard corals.

My point is that if phosphates are a problem, it will read above 0, and if it doesn't and I'm having a problem, then phosphates aren't the problem.

Wow there's gotta be a better way to say that haha
