Sounds a bit weird! Guano I think (from birds at least) should be a bit acidic if anything. Maybe ths could dissolve calcium from the roof (if you had a concrete roof tiles or other roof covering rich in calcium) which would then end up in the tank. Warming of this water might cause some precipitation of calcium carbonate but I would be very surprised if it were substantial. Could pore blockage be an accumulation of dust rather than calcification?

As for the eels! I have no idea why they would help. Maybe a little respiatory CO2 would keep the pH down… Small fish in relatively open tanks can be a good idea to keep mosquito larvae in check. I’d think a couple of goldfish would do the trick though.
