So apparently they discontinued the Acurite model I set my 20g up with. This model number is the replacement and I bought it. I set my new tank up last night, but ever since it has been in, the humidity part just reads HI. I put a different hygrometer in and it is showing humidity of 77%. I noticed on the Acurite that when it hits 90% it goes to HI. If that's true then the humidity is over 90% and has been for about a day. I'm not sure of the accuracy of this model. Does anyone have experience with it?
Is it dangerous to have it that high for so long? I expect a lot of it is from the new substrate. I'm contemplating getting a new humidity meter under the circumstances.
I'm wanting this to be a successful transition, but I'm concerned about the humidity issue. Any ideas or help??
