I have that light green silk plant in the middle too! The problem is that the way the are packed is inconvenient because it folds up the plant so when its in the tank it is almost always just straight up.
I didnt know petco sand raises Ph! No wonder I have insanely high Ph! My natural Ph is high, how much does petco sand raise it? What kind of sand can I use that wont raise Ph!? Sorry to hijack, im just worried lol.
I would say 6.8-7.6 is a good pH range. You wanna keep it somewhat constant. The lower the number the more acidic it is. So anything less then 6 is bad and anything over 8 is bad. That is what I have read.
0 is a very low ph and very acidic. I can't hink of any substances that acidic. I don't think there is a 0 but only as low as 1. Either way that is VERY acidic. Like serious burns acidic. 10 is high and pretty basic and also dangerous to fish. Your ph should be towards neutral or 7. The pH scale is from 1-14, 1 being the most acidic and 14 being most basic. Stuff like household cleaners are basic, and citrus is acidic. The most acidic thing I can think of is nitric acid. Second to that would be car battery acid. That stuff is also pretty dangerous. Lol sorry for going on about it but I'm sort of a chemistry nerd.
