Sea Side Aquatics Magnetic Probe Holder

Use for 4 years and magnet swelled. I paid $30 so that seems pretty good use for me.

The only downside I could see is if the magnet ever rusted... but then I would just soak it in vinegar, scrub with the fish toothbrush and seal it in silicone or epoxy like a sane human being. I really like everything about this holder.

Threads were not quite cut right on a couple holes. A couple of the plastic screws were very hard to install. The magnet is certainly adequate and it is completely encased within the plastic which is great because I heard of rust in other brands. They got it right with this one.

now no more water and calcium spill. Everything line up nice and neat

I needed a firmer hold on probes in sump and this did the trick. Magnet is pretty strong.

This Sea Side Aquatics Magnetic Probe Holder is the best thing I have perches, it kips my probe in please and well hold. I do recommend it

Literally have no clue what I just got. Returning this. Didnt even have a magnet. Nothing like the picture

great addition to my tank, able to hold my probes without a problem
