DIY bubble counter >$5.00

[rolloffhill]

I picked up this idea from Wasserpest on tpt.net, such a good idea I couldn't pass it up.

I picked up a check valve from petsmart for ~$1.50


and an oral syringe from CVS for ~$2.99





It is a simple DIY, just need to put a bead of aquarium safe silicone around the check valve and slide it right in.


After that just make sure the silicone is sealed up good and let it cure. The check valve won't be the only one I use. I have brass one coming that will go between the regulator and the bubble counter for extra safety.


I'll be using Mineral Oil on the inside to keep evaporation down and not have to mess with it very often.

Now I just need to find something to mount it underneath my stand...
