Hey Mate a Good Thursday Morning video down here today👍. The Kactoily meter is a great idea love it and the ease of set up and use is great. And Nerdy stuff is always good It's cool you can just have a look and know exactly what's going on👍. I'm with you about PH unless your readings are in the extreme ends of the scale regular water changes should keep things in check. Unless you have fish that are from places that require specific levels. Anyway cool video man. Good onya Mate👍👍🙂..
