Viagrow PH up Crystals???

can anyone tell me how much ph up crystal you put in a gal of water to bring it up a 1point need to go from 6. to 7. (soil kinda low and my tester is on the fritz) Thanks all in advance

No I cant, sorry. But I think I saw PH testing strips at Kmart and they didnt look too expensive. It was by the pool stuff.

It depends on the alkalinity of your water source. RO water will take much less to affect pH than well water. There is no blanket answer that will apply to all situations.
