Hi, just done a test on my new aquarium which had been maturing well with live rock for a month now. The dKH level is 22 dKH which is way too high. I know what to do if it is too low but what do i do when it is too high? Thanks
I have beeb using my brothers RO Filter unit which has been emptying into a 200 litre water butt in the greenhouse. I did a quick test on the nitrate levels in the water and it was still 10mg. I guess he hasn't changed the filters for a while, which might explain these high KH levels.
