New to CO2 injection: A few questions

[Toss]

Try to turn off AC110 for a day and see if that improve the CO2 concentration in the tank.

Would having filter floss in my AC500 or Canister filter somehow impede the flow of CO2 bubbles?  I removed the floss I had in my Eheim but still have some in my AC500.

Since you are using a ph controller, you can check the controller to see it's on all the time or it's on an off intermittent. At least you get rid of one of the possible causes! If it's on all the time, you know right the way, you need to increase the Co2 more and see.

[Ormarr]

Well, it turns out my AC110 was out-gassing more than I thought it would.  I turned it off during the day and the PH dropped to 6.5 without a hitch.  Is it a good idea to turn the AC110 on again when the lights go out to out-gas some of the CO2 at night?  I will eventually get another canister (probably after the holidays).

Thanks for the help/info. everyone!

Yes you could put the ac110 on a timer to match the lights going out and coming on again, you could also put that canister under the tree and label it "for the fish from Santa", no one ever questions gifts from the big guy!

Problem is, the big guy has been buying a whole lot of fish related products throughout the year.  Mrs. Clause is starting to catch on.

Yeah I wore out that Santa fish scenario cover story awhile ago now...

Sometimes it is hard to get the ACs going without priming. Make sure you are around the first couple times. I had a power outage waitied around but then had to go out for an appointment. When I got back 2 hours later one of my ACs was running dry the powered come on... Yikes... it was OK in the end though, gladly...

I would recommend not putting a filter (any kind) on a timer. Filter is meant to be on 24/7 with exception of cleaning time. It is not good for the bacteria live in the media, especially hang on back (HOB) type since some water drain back to the tank as soon as you turn it off. Also there is a chance that the impeller might not restart again (like Dan said) due to some debris settled inside the impeller housing. If you have some MTS (snail) and your aquaclear is off, there is a big chance that one of them will sneak into the impeller housing and jam it. When the impeller is jammed for a long period of time, the housing will get really hot and bad things usually happen after that.

One last question...(for now  )

Say the PH drops to 6.6 (desired target, about 25ppm of CO2).  If I wake up the next morning and the PH is 6.7 (20ppm or so), is this a good thing or is it best to release some of the CO2 at night and start again from 7.2 (where it usually goes back to with the HOB on at night)?

Sorry to rain on the conversation, but what is the purpose of a complicated an expansive PH controller when you can acheive the same with bubble count, solenoid and a simple Drop Checker?

If your worried about O2 levels put an airstone or bubble wand on a timer to start after lights out. Alot easier than an AC.

As long as you stay above 15ppm, you are fine
