Mold in sump cabinet

[Baldy]

Hello,

I have recently noticed mold starting to grow in the cabinet under my tank where the sump is located. I had no ventilation in there before, and added a fan a couple weeks ago. ive been running the fan intermittently to try and avoid excessive evaporation, but im worried that this mold is going to become a problem

any advice?

Sounds like you might need to re seal your stand after a good cleaning & possibly a little sanding. I found that if a wood stand is not completely sealed the wood will soak up the moisture and eventually mold.

wash the cabinet with diluted bleach and reseal

The unfortunate part is the tank is up and running, and I have nowhere to put everything to tear it down. I was more thinking of a way to get the mold off the wood. Would a rag soaked in bleach solution be ok?

I'm not really attached to the cabinet. If I set up a new tank or move this one, ill be building another as its not optimal for having a sump

Paint. Waterproof paint is best.

I use a waterproof masonary paint and it works perfectly. And it's kind of rubbery it seals any cracks or seals.
