Floating Probe Holder for Saltwater Mixing Station

[joshuazepstein]

I have some extra equipment and would like to add some probes and heaters to my saltwater mixing station. It’s a 55 gallon/44 inch tall container. Saltwater is pumped into it via 1” pvc that goes straight down from top to almost the bottom. Since some of the probes cannot be fully submerged, I’m thinking of a floating ring that goes on the vertical pvc pipe. That way the probes float up and down depending on the depth of water in the tank.

FWIW - Don’t fight me on the necessity of this. I know it’s not needed but would be a nice to have.

Question - any fatal flaws with this plan? And any suggestions on materials for the floating ring? I’ve thought about cork since it’s easy to work with but open to anything else.

My first thought was just a floating piece of foam to hold the probes.

Good luck!

What kind of foam is reef safe?

Polyethylene foam can be reef safe, here's a post describing how to test it:

You could use a short piece of 2-inch PVC, placed over your 1-inch PVC, so that it will slide up and down. Attach the heater and probe to that. You may have to add some weight.
