DIY Kalk Reactor and Sump

[BCOrchidGuy]

Yes the um lip around the top etc?

It's just siliconed on for now I couldn't find gasket material and I didn't want to put a lot of time into it. The top off water goes in through the bottom the rigid tubing has a bend in it so the kalk stirs a bit on it's own as water moves through. It seems to work well. I'm not excited about the look but like I say it works so that's good enough for now.
