Thoughts on over skimming

It takes a few weeks to a month to full the collection cup, on my previous setup it would only take a week.

By similar problems do you mean just the fizzing or problems with corals as well?

I had zero growth out of softies and LPS, SPS had slow growth. Skimmer would just sit there and fizz. I dropped my skimmer down to one pump and everything seemed to be improving when I lost my light timer while on holidays and the tank went without light for a few weeks. So I'm unable to confirm whether the improvement would have continued.

The 90 gallon was very low tech, maintained with skimmer and water changes only,plus a tad bit of cal. dosing
