Does a stronger water pump help with air bubbles?

[Pixelbender]

Does anyone have experience in this area? After hooking up my pump again the other day I noticed a ton of small bubbles in the top of the laser, I wonder if a stronger pump would help evacuate these. Better pumps seem pretty cheap at HF.

I've got one of the pond pumps from HF, seems to work well. I added a bottle of "Water Wetter" to my coolant and that appears to take care of the bubbles I had.

It also adds color back to the coolant. I have straight RV winterizing coolant and the color goes away for some unexplained reason.

You should be able to find the water wetter at you local automotive parts store.

It is about elevation issue. You need to settle the tube 5 degree up (output end) and the bubbles will be sucked out smoothly.
Adding coolant is good for 'viewing' as it show a little green/yellow. Also, it will prevent algae from growing and icing.

Also, you need to make sure that the water outlet on the tube is up right so bubble/water can be pumped out freely

I would like to add to JAV-1 and Marco. The recurring air bubbles are an indication
of cavitation(too strong motor on the pump, making the dissolved air to separate).
2-3gpm flow is sufficiently enough. Also you might benefit from adding a reservoir,
that is at a higher level than the tube(preventing any bubbles in the tube making a
round trip to the tube, by allowing the bubbles to escape to the surface).
