Is airating the water necessary? Once heard this but his reasoning did not make sense to me.

I should also note that the majority of the time the reservoir will only have 10G. 10G is about 5 days water. I'll only be filling before vacations.

I run a heater (optional) and a MJ600 in my 10g ATO
I'd think aerating it would be fine, but you may splash everything around it with the popping bubbles
It's up to you - air pump or powerhead

My ATO tank is out of direct light, but still gets ambient light
I've not had any issues with algae of any kind, only slime. This we suspect was coming from the RO as I was getting air in my RO system between uses, so it's most likely a bacterial buildup

I plan on cleaning out my ATO soon so I expect the slimy-eggwhite crap to go away
