I opened the lid of the hot tub today and omg. I almost threw up. We moved into a house with a hot tub and before dumping and starting over fresh this has happened one time. We scrubbed it clean, emptied and got all of our chemicals right per the spa store down the street. We’ve only used it once though. Anyway... these maggot looking things are covering every corner under the lid and there are ants just eating away at it. I mean thousands ... I couldn’t believe it. I’m about to get rid of the whole hot tub if I have to keep emptying and treating like this. It’s only been 2 months since we last emptied. What’s causing this??
