I lost the bottom of my CYA test bottle. I still have the screw-on top. As it turns out, the Taylor reagent bottles, once you pop out the dropper, is pretty much the exact same bottle. Since I am a cheap sob, would it be ok to clean and reuse a reagent bottle for a CYA 7ml/14ml mixing bottle?

Lately my pump has been not starting. It's on a timer to come on 2X a day, for a few hours while on. Sometimes I find it not on and to get it going I either cycle through the on/off switch located on the pump, or I whack it with a screwdriver and it starts up. Is there some maintenance I can do...

Hi all. Great forum to learn. Thanks. While my ph was 7.6 and CYA~50, I let my FC get down to .8. I added too much 10% CL at once. About 1/2 gallon. My ph rose to 8.0 while the FC was 5.2. The ph setteled down to 7.6 as the FC fell to 4. Is that normal?
