Im not sure about raising my bubble count since I use my controller to maintain pH. Do you mean lower the pH.

Did some more research online, and I think that my effluent flow rate was way too low. At about 90 drips per minute that is only about 9 ml per minute. Everything I read online suggest that I should start out between 30 and 50 ml per minute.

Red Sea Reefer 450 (approx. 92 gallons of water). Using ARM extra course media with about 10% ZH magnesium.

Hello. I was worried about the probe, so the other day I pulled it out and compared the tank reading to my tank ph probe. They were basically identical. Also is in line with my calibration solution.

Last Saturday I added a GEO612 calcium reactor. The chamber pH is set at 6.5 (using my Apex controller). I started the effluent drip rate at approx. 50 drips/min. Each day I have tested the Alk which started out about 7.3. It has steadily dropped down each day to about 6.5 today. Yesterday I increased the drips to approx 90/min, but the Alk keeps going down. This is the same problem I had before I got the reactor. My pH has been steady at 7.9-8.14. I tested my Ca once last Sunday and it was at 420. Does it take a while for the media to start breaking down?

I've always just used a valve and drip rate. How do I use this to control effluent?

Okay, I'm sitting here having worked with a new calcium reactor for about a week. I'm frustrated with the difficulty and adjusting the affluent flow from the needle valve. I have heard discussions about peristaltic pumps on the Forum. Can anyone recommend some links to peristaltic pumps that are halfway affordable? Here's one mentioned on eBay. Would this work with an Apex controller? http://www.ebay.com/itm/MILWAUKEE-MP810-PH-LIQUID-DOSING-PUMP-3-8-GPD-PERISTALTIC-AQUARIUM-MARINE-REEF-/121705183480

Never did. Maybe I just had a lot of air in the chamber. Ended up setting chamber pH at 6.5 and its been steady. Double checked with tank pH probe and it showed same.

What LED light do you have? Amazon?

There was a lot of air in the reactor, since I had just turned it on.

I had the CA probe in the tank with my other PH probe and the readings were the same.

I'm setting up a calcium reactor. I've got everything going, except the CO2. The chamber is full of media. My PH is reading about 9.88, while my tank is at 8.3. Would this be right. Would the media increase the PH?

Thx. Zealanders got me covered.

Still looking for 5lb tank

Thanks for the offer. I think I'll stick with 5 pounds. Good price though.

Looking for a 5lb CO2 tank. Or, where's the cheapest place in the area to buy them?

Is there any online sources for packs like this. Even though I shipped my rock in live and cycled it for weeks I lost most goodies.

BicycleBill, do you recommend the MMA with a range from 10-150? Also, does the meter actually control the effluent, or just show the flow rate?

Does the valve go on the input or output (effluent) tube?

Crap. Good to know. thx

Thx. Went to home Depot and found two brass fittings that allowed me to go straight from outlet to valve. Could have used plastic but would have had to use a piece of tubing in between.

I'm in Tualatin but might give it a try

Where can I find the fitting necessary to go from my calcium reactor effluent output to to a needle valve? It looks like maybe I need a quarter inch male to 1/2 inch female fitting?

Yes. Pickup available tomorrow after 5pm. PayPal or cash.
