DIY Bubble Counter

Since I absoultly refuse to pay $50 for a bubble counter that will hang on the side of the tank I decided to build this today. I saw a description of it mentioned else where on this forum so I took a few pics to document it.

First you need a check valve and a oral syringe:


Next remove the plunger:


I cut the bottom of it off so it would sit nicely against the tank:


I sanded the bottom smooth:


I used GE Silicone II to secure the check valve in place:



And the final result installed on the tank:

That's a neat simple bubble counter. I wonder how long the plastic check valve will continue to work - my experience with various plastic ones was very bad. I have several unopened syringes that could be used for these, if I still used CO2.

yeah I have a couple of the syringes and check valves. I also have another check valve before the needle valve just as a fail safe.

Nice! This is a good idea. I use a jar type bubble counter. Not because I dont "believe" in bubble counters. Only that I believe that theyre way too expenisve when you can stick the hose underwater to get a reading. I may try this idea out myself.

Are bubble counters really _THAT_ expensive? I can get some and sell em pretty cheap... I just didn't think there was a demand for them. I've never bought one before, they've just come with regulators or diffusers

They aren't real expensive, but they can be so simple it hurts to pay for one.

I'm a DIY type at heart, and I understand the feeling of satisfaction one gets when they've made something that works. I wold be hard-pressed, however, to justify the time spent on this vs the cost of one unless I was just trying to have some fun.

I was using a jar style one. I had a JBJ one on order but that got "lost" in the pacific somewhere so I was refunded for it. I wanted to clean up under my tank a bit so putting it on the side of the tank out of the way helps with that.

Since it was only about $5 in parts and took all of 5 minutes to make, if it leaks or fails, who cares. I build another one.

Yeah, Cheap bubble counters arent cheap when you need 9 of them. This is a easy, cheap way out for sure. Thanks.
