Yeah so I did a PH test on my planted tank and it came back like 7.6. I am like wtf? . so then I remembered I knocked over a picture frame and I saw it pulled out the co2 airline. hmm.. so I put it back in and an hour later it was down to 7. and this morning it's back at 6. ahh. pearling plants.
lol. so be careful around yer aquariums :D
