Snail 'Tank'

This is my new snail 'tank', they will be living in here from now on. I finally sold my 20 & 30gal tanks, so I had to find them a new place to live. The 3 Apple snails also live here, several Pond snails and a few others that look kinda like a cross between apple and pond but have bumps on them like tiny spikes. I'm guessing it's about a 10Gal, maybe 15Gal, it's on my dryer so I hope the vibrations of it being on don't annoy the snails. The green little clear bucket is where I grew algae, fake plants have TONS of egg sacks on them, same 20/30g rated filter from their old tank and another clear bucket that I also used for algae but it failed to grow, so hopefully it'll grow now and it will give the snails more surface area to munch on.
What do you guys think? What should I be feeding them and how do I care for the egg sacks? How long before they hatch and/or how do I know they are viable??

Those darned Apple snails keep breeding but refusing to lay eggs, so I'm not worried about them. They never went out of the water in my other tanks, if I'm cleaning sand and the water level drops past them, they let go and sink to the bottom. If they do get out and onto the floor, dinner for my Chi mix dog. The filter is a turtle filter and has a small nozzle that pushes water around nicely.

I have nothing to cover it with either way. They have been in at least 4 different tanks, all open top since my fish don't fly on little fish dares between each other.

I might have to put my male Opaline in with them since I may be selling the tank he is in and my female Opaline hates him...
Oh, I will be taking pics of cute little snail munching tracks in a second. They found the algae tub I was growing last night! Snails do clean glass, but you have to be an ant to be able to see through them well, lol.
