What PH test do you use?

Ive been getting kind of annoyed at the similiarities between different PHs on the color chart of my aquarium pharm. Ph test kit, and I was wondering what Ph kits you use, if any?
what would be a decent alternative from aquarium pharm. thats easier to read and still decently cheap?

Ive looked into lamotte and hach, but that seems pretty useless to me, cause 1 ph test kit could pay for half of a Ph Controller, or a Ph Moniter. Im guessing the prices area bout 50 bucks + for a kit, unless im looking in the wrong place.

on that note, does anyone use one of the digital PH testers from milwaulkee?

I gave up on the tests and went to a pH pen meter for the very frustrations. It only cost me around $45-50 and that is just about what the LaMotte was going to cost. It is a pH 53 with +/-0.02 pH Accuracy. Just read the numbers and never guess about colors again. I think I bought mine from Glass-Gardens.

i use pinpoint digital pH reader. gives readings in increments of .01pH. very nice for co2 injection fine-tuning.

assuming you have good calibration fluid, it should be the best alternative. I think Milwaukee's product is very similar. Supposively has less of an accuracy range though.

As for fluid pH testers, I have found AP to be the best of the few I have used. The color ranges seem quite wide-spread for me. Especially given there is a .2 range of error on them. You are theoretically guessing anyway once you get the color.

i use api's kits, tried nitrite, ph, gh, kh, ammonia... theve allways seemed to work pretty well, and there years old (except the KH, although its proberly been on the shelf at the LFS for about 2 years)

i might get a pp pen just for the convinience of the PH test, but ide say PH kits are pretty much all the same regents.

whos paid 45 for a lamotte kit ??

I can definitely relate to this thread. I finally gave up tweaking the bubble rate and ordered a pH controller last Friday. I'm hoping that with the controller and the cheap test kit for validation, I can have a better feel for the pH levels and can tweak the level more easily. But....I bet a digital pH reading will be in my future!
