Hi. Get yourself a digital Ph meter and Ph 7 buffer to keep it calibrated. I use mine almost daily and, colour blind or not, it's just so convenient.

I've read about those. What brand do you have and cost. You got a link. I'd love to have one. I've heard some ate cheap and useless.

Hey where'd you get it and what brand.

Sorry for double post.

I bought a pocket Ph meter off EBay. It was about £10. Amazon do them too. Can't see a make but it's yellow! They are not the best in the world, (pay more and you get into the scientific range) but with weekly calibration, it takes seconds to do, I find it a good indication of the Ph trend. You need to purchase a bottle of Buffer to calibrate, best to buy Ph 7, and just keep an eye that the meter is calibrated. Once I had mine set up it didn't wander more than 0.1.

When I was new and sweating whether I was at 7.6 or 7.8, our LFS (one of the biggest freshwater stores in the country) told me to quit using the API test and start using a hydroponics kit that tests from 3-10 in one test and breaks it up only as far as 6, 7, 7.5, 8, 9 ...

Their point was if it's between 6 and 8 and stable it's fine for most fish.

So you don't need to worry about exactly which color it is, just that it's a similar color as last time.

I have very soft water with few buffers and the pH fluctuates a tiny bit, but all the fish are healthy after many months of this.
