pH and water quality
I got my floating raft system setup in the basement this weekend. I also have the lettuce seeds started and hope to transplat them into the hydroponics system soon.
My pH is high. Like 7.8pH and 250ppm at 59 degrees. I used our tap water and i know it is pretty hard.
I got some pH down from the aquarium store (was easier then driving an hour to the nearest hydroponic store) and added some of that (said two drops per gallon). It seems to bring the pH down to 7.5 last night, but when i checked it again this morning it was back up to 7.8.
Do i go buy bottled water and not use our tap water?
Do i need to get better pH down solution?
