Was it open full when you got it? It looks like it should recover. I would put it in a low flow, low light spot until the recession stops. I have some coral dip at the shop I can give you to try if you want. No charge.
No babies here so I don't have much advice. But good luck Eric. Whatever you do don't let him puke on the floor at aquarium shops. This happened in our shop last week. I am still traumatized from the incident.
Fortunately the city isn't liable if someone gets hurt. This is a recent change however. The liability is the main reason these parks weren't around in the past.
I think it is a great place for kids and adults to get recreation and stay out of trouble. I have been a skateboarder for 17 years now and I think if there had been a place like that I could have progressed faster without the tickets and skateboard confiscations.
I don't think there are to many members that skateboard but if you do or know someone who does you should know about Ed Benedict park on 102nd and Powell. There are many skateparks in the area but this one is the best I have seen yet! The first time I saw it I thought I had died and gone to heaven.
