So my straight from the tap water is about 7.5 pH, and gh 160s... I recently got some very lovely looking rock, unfortunately it raises gh.. so now I can't even tell how high it is. API GH test kit only goes up to 12 drops = __ gh... it took 16 to get the color change from 1 week of soaking in water.
SO are there any adverse effects of having off the charts GH? I don't plant to use this in tanks with (wild caught)fish/plants that needs super low gh.. but does it have any bad effect on more tolerant plants or fish?
