I am only a couple of weeks into pool ownership. I am not generally squeamish, but i am developing a healthy concern for pulling the cover off of the skimmer. In my 2 weeks I have opened it up to find 3 wet and very unhappy huge bumble bees (thankfully wet and cold makes for slow bees), a giant spider (ok, giant is a relative term, but it was really big), roughly 12 million rollly polly bugs clinging to the underside of the cover, and on our warmest day I found a snake just a few inches away from the cover sunning itself (I had been pulling shrubs and assume I disturbed it's winter den) - thankfully it was just a rat snake and harmless and it was technically not IN the skimmer, but it really made me think about the fact that warm weather may change where I am finding snakes.
So, I am getting concerned with sticking my fingers into the little holes on the cover. The cover is new and fits tightly so I really have to yank on it. I assume there is some tool for this job? What is it called because I am coming up with nothing when I search "skimmer cover remover thingie".
