I'll show mine if you show yours??
Alright, I made mine today. I'll have 3 hatcheries going (I think) but I'm just testing it with one right now since I don't have any ponies yet. I've read of people using 2 liter bottles and then these canning jars. I like the canning jar because of the lid. So, if this works out like I think it will, I'll do the other two.
I installed a shelf above my newly installed ro/di unit. I then placed an air pump on it with a 3-gang valve (for the 3 hatcheries). I have a basket shelf underneath with a measuring cup and a couple of bar towels.
Decaping wasn't hard; if I did it right.
I didn't see the eggs turn orange/yellow, they just looked yellowish after a few minutes.
I attached a 1x1 wooden dowel (is it still a dowel if it is square???) above it on a piece of existing wood. There is room all around the dowel so that I can move my clip on light around.
