Hoppy: I had an idea while standing in the shower this morning, like you do.

What do you think to the idea of making a drop checker, with a ph controller probe glued into it? That way a PH controller might actually become useful instead of so hit and miss like they are at the moment, because of all the other tank born PH altering elements.

Dont know how feasable it would be to do, because frankly I dont know how big a PH probe is, but it seems to me that if it could be done, you would have a pretty amazingly accurate way of controlling things.
