vindy500 Posted June 29, 2008 Report Share Posted June 29, 2008 So a little while ago i used the wrong sand and it shot up to a rediculously high ph.. but now i have changed the sand to aquarium stones and put peat underneath them... and the ph is still higher than my kit can read!

SpidersWeb Posted June 29, 2008 Report Share Posted June 29, 2008 Well the pH will stay high until the water is changed, or some of the calcium etc is absorbed in to the peat which may not happen as it's under the gravel. I always use a high pH kit, because usually the water was around 7.5 to 7.8 which is fine for most fish that I've owned and the degree of hardness is just enough to keep pH stable but without going overboard. It can be on the bad side of a normal pH kit. If your pH is over 8, then there must be something seriously adding hardness to the water, such as shells. Something else that used to stuff me up a few times, is making sure the tube and lid you are using are completely rinsed with clean water before use. The left over chemicals from other tests can often interfere and give crazy result readings. If your pH is in the 7's I'd say your fine, but over 7.8 and you've got a problem (unless its intentional). Quote Link to comment Share on other sites More sharing options...
