Semi-seal ATO reservoir

[Oshengems]

hello everyone I recently picked up a 10g ato reservoir to replace my Home Depot bucket lol. From the 5g bucket I was getting 5-6 days of top off I was covered and had 2 tiny holes for the line and pumps wired. The new ato 10g I’m barely getting 8 days I want to seal the edges and maybe the hole for
The pump in the back to see if I could get at least 10 days of ato. I feel it’s too open and maybe it’s evaporating faster. Here’s a few pic of all 3 openings sorry for the dusty pics. I wanted to know what can I do to semi seal it since I don’t open it much

Can you measure the hole and get one of those desk or countertop grommets that’s used for wires to come out of ?
They have some different sizes....not water tight but enough to close it up a lot...

This will work for the hole if it's a two inch hole. If it isn't there's probably something similar you can find
