All seems in order hose wise - no kinks, no bypass, I can bleed any air out but the noise happens when the bubble exits into the cylinder so having air at the top is not the issue. How many BPS are you running your at? I'm running at 2 per second at the moment but it does go quieter if I throttle back slightly.TDI-line said:Ray,
the only thing that i can think may need doing is to bleed the reactor at the vent point.
Mine was extremely noisy at initial setup, but after i removed all traces of air from the unit, she then become very quiet.
Not trying to teach you to suck eggs, but you don't have any kinks on your hoses do you?
Mine also has the bypass, so i had this opened when setting up, but turned it off for normal operation.
Yes, now - must admit I did plumb it in wrong to start with Cue another half hours swearing inside my cabinet. How long are you getting out of 2kg on 2bps with this reactor? Its got noisier, I wonder if a clean would sort it. Or wack the CO2 right up to clear any blockage!TDI-line said:Hmmmm.
Mine is running around 2 per second also.
Is your flow in at the top, and out at the bottom?
I looked at this one and would have gone for it with matching Solenoid and Regulator except they only take 12/16mm tubing. Can you get them yet with 16/22? The filter idea is neat, but I guess it impacts flow somewhat?The Aqua Medic is a large reactor that is perfect for the larger tank. We use them on our "big boys" in store and find them highly efficient. By replacing the plastic balls with Sera's Siporax a HIGHLY efficient secondary biological filter is created and both flow and CO2 dispersion rates seem greatly improved.Its also quite nice to free up space in the tank by mounting inline inside the cabinet.
OK, just like the Aquamas so you have the same problem. Inherant issue with the reactor concept except perhaps the Cal Aqua one. I wonder if a valve exists that bleeds air but not water?The-Green-Machine said:there is a "bleed" valve in the top of the Aqua-Medic reactor making the process very simple.
Thank you James, that is extremely helpful. Flow is certainly good through the Aquamas - mine is also on a 2028 and after 10 days operation with full media load, Aquamas reactor and Hydor inline heater this 1050lph filter can fill a 2l jug in 9 seconds which is 800lph real flow. It is a bottom drilled tank, which might help.JamesC said:As long as you've got decent flow going through the reactor you shouldn't have any problems with gas build up. I run mine on the outlet of an Eheim 2028 and it runs almost silently with no gas build-up at the top. The only faint noise is of the CO2 gas bubbling in from the inlet tube. If this is a concern you could attach an airstone to a small length of airline and attach it to the inlet tube inside the reactor. May need a bit of thought to how it can be done, but should be possible. I have replaced the small length of tubing from the bleed valve and put a length of airline that runs in the top of the tank with the valve attached there. When doing a water change or maintenance and air gets in the system it's easy to vent off and not worry about any water that comes out.
