Hi

I have a newly setup Reef Octopus Calcreact150 as per Youtube Videos and looking for some ways to purge the air from the system as there is a lot of whooshing noise.

Looking at other Reef2Reef threads I have not turned on the CO2 as yet and all valves (apart from CO2 recirculating) are fully open.

Reactor is being Fed from a Return Pump Tee.

Varios2 Recirc pump is set to full

CO2 Recirculating Valve is fully closed.

Top of the Reactor is about a metre above the sump in a cabinet. Sump is remote from the tank

Effluent line is about 1.5mtrs long into the sump with no needle valve installed.

I can see air bubbles under the upper filter pad but no amount of banging on the side of the reactor appears to move them.

I have Caribsea Arm Extra Large Media

Should I just let it run like this for 24 hours or more ?

Some guidance would be very much appreciated.

Regard, Andrew

Hello Andrew!

Sorry to hear you’re having troubles. This is usually a minor inconvenience. Please make sure to check all of your connections and seals because you might be sucking in air .
Please review this video starting at 8:14 . If this doesn’t help then again check all of your connections closely. :)

I would make sure your using new tubing if any so its not old. also use either plastic hose clamps or the metal ones to go around those tunes to ensure a tight fit. I have air in the top of my reactor under the lid but was told on a new setup it will eventually work itself out.

Guys thanks for your replies. Been a few hours now and I have opened the CO2 recirc valve to about 10% and not getting any more whooshing!

I have a valve installed on the water input to the pump which I am using to restrict the flow into the reactor from the T off the return pump the effluent mls out is 45 and have 1 bubble of CO2 per 5 seconds.

In The absence of a peri pump is this the best way to do it as I fear having a needle valve on the effluent line will in time clog
thanks

Andrew

thanks it was helpful

do you recommend having the CO2 recirculating valve fully open, partially open or closed for normal operation

Fully Open :)

It’s better to lower the speed of the pump then to throttle it back with the gateway. That’s the reason why we put the variable speed pump on it.

Hi if I do that I just get the air inside recirculating round and round creating a lot of noise.

I have no CO2 on at this time and the pump at its lowest speed

i need to work out how to purge the air inside as its driving me nuts

thanks

To purge the air, you'll have to bleed off from the top, and at that point partially close the valve. That will create the pressure that will push the air or excess CO2 from within the chamber.

Im sorry, the water valve for the recirculation pump. The more you close that, the more pressure creates to push the excess CO2 or air out of the main chamber. You will have to open up one of the quick connect valves at the top to allow the excess CO2 or air to bleed out.

Michael - OK I believe I have fixed the issue. I opened all valves fully for a few minutes, Next I closed the Effluent outlet valve half way, the CO2 recirc still fully open and the pump feed valve half way - this obviously created some pressure inside the reactor which purged the air. I now have the pump running at full power with only the odd CO2 bubble fizzing through. Your help was much appreciated. Andrew
 

Do you have a iPad or similar type screen mounted somewhere near your tank for control or display?
