Problems with high kh? to high=very bad?

Hi RC,

My 90g is in the process of being cycled and admittedly it has been neglected over the past few weeks. I wanted to spend more time taking care of the tank and monitoring the levels and noticed the dkh is through the roof. I am measuring about 27! I thought this was a mistake but I checked again and it is still very high.

I think this could be partly due to my attempt to raise the PH using proper 8.2. I mistakenly thought my ph probe was working and I have probably added to much buffer over the last few days in an attempt to get a broken ph probe to respond. In any event, I wanted to determine if this high of a dkh is terrible or if it is ok. There are currently no inhabitants in the tank. PH appears to be around 8.4 using the liquid tests.

If it is bad please recommend a solution. I suppose water changes would work? Thanks in advance!

The pH buffers all add alkalinity, so that's likely the issue. They don't work well. Low pH levels are common during the initial tank setup period since many decay byproducts are acidic, so the problem might go away on its own. I'd ditch the buffer product. The alkalinity should drop on its own, but a few water changes after or during the cycle never hurt water quality.

This article covers what chemicals will need to be dosed:
