Help please I ran out of PH Tester liquid today, and tomorrow I flush (noticed i was out of ph after filling the res up and getting it ready for tomorrow), the fucked up thing is tomorrow is Friday. If I order some tomorrow it will ship probably Monday, and get here probably on Thursday or Friday. I went to WALMART, K MART, LOWES, HOME DEPOT and all they had was ph test strips that only go down to 6.2 and I need to get it down to 5.6 so those strips will not help. What should I do? Is there any home remedies to test the PH?
Thx. Any advice at this point will be GREATLY APPRECIATED......
