correct ph tablets..... and problems reading this ph chart from ph strips

i picked up these things at wally world for aquariums. they are tablets that are supposed to ballance the ph of water to 6.8-7.2. so im thinking that I can use these to ph my water before giving it to my soil based plants.
I went to get some ph up and down from wally world and they have stopped carrying it because it is a seasonal item....

also. are these strips ph strips? i think i remember them as being so but i dont remember how to read the chart to see if it is to acidic or too alkaline....
yeah they are...says so one the back. says that the soloution should have a ph of 7.5 or lower..... so thats as high as they read. how do i read this damn chart on the front

help!!!!someone.......

same questions again all over......

ok report. i never actually tried a ph meter to check the ph of these things.... but i know that it is better than not having anything to adjust your ph. By FAR.

i have been using ph tablets from your local pets department and they seem to work well and puts the water at a safe ph levels for plants or fish!!!!!!!!
levels should come out to be right at 7.0 or lower depending on how many tablets you use. there really cheap !!!!
