Lol there is some truth to this. Overall my tank looks happier with higher ph, that's my main reason. I have noticed slightly faster growth rates since starting Co2 scrubbing. But yes, not watching daily helps a lot too. Haha.
Purely a placebo effect on my part but honestly I couldn’t tell the difference in my tank. I got lazy and let the media get depleted and nothing really changed. With the new build, I’m going to keep it simple and neglect pH completely.
I've gotten 0.3 delta from scrubbing when fresh.
Hmmm - this would be odd in my opinion. Are you absolutely sure your pH meter is correct? I mean - I routinely ran the tank in my build thread - and the pH fluctuated from 7.9 to 8.1 or so. Rarely (very) down to 7.8 - that usually signaled a problem. However, I was thinking about your issue - what is your alkalinity? Do you think it might help to change your dosing (if you're doing any) to a Kalkwasser method? Also There are different media for CO2 scrubbers that can be used besides CA hydroxide.
I do dose kalkwasser lol. Alk is around 8.5. I will try drying the incoming air from both the skimmer and the outside, I'll see if either works. Tang is 233g display / 265g total
I would seriously make absolutely sure that your pH measure is correct. But - yes - please do keep everyone updated - as that is probably the most important - i.e. was the diagnosis/advice correct (or not)
I see your problem. You aren’t recirculating anything with this setup. All the CO2 depleted air is escaping the skimmer lid. Your yellow line needs to go directly to the top of the skimmer, not the separate collection cup. In addition, you can tape of some or all of the vent holes on your skimmer lid to make most efficient.
Changed June 26th
Blue = outside air line
Red = skimmer to collection cup
Yellow = collection cup to scrubber
Green = scrubber to skimmer intake
Skimmer has a locker with multiple overflow protection
Hmmm please explain more. The holes on the top of the lid ARE capped and hot glue sealed.
Read my post edits lol.Hmmm please explain more. The holes on the top of the lid ARE capped and hot glue sealed.
The yellow line is goes from the moisture collection cup to the intake side of the Co2 scrubber.
The green line goes to the intake of the skimmer and is co2 free.
But, maybe this is wrong?? I followed fish of hex on YouTube and how he did it.
Do you have a large bio load in your tank ie, large number of tangs, large fish load? If you do then amount of media relative to your dissolved CO2 levels in your reef may be too low, hence the media being used up quicker than expected. Do you have an algae scrubber or refugium with algae on your system? May help to raise your pH without burning through expensive media. Kinda like some reefers who will run calcium reactor output through algae device to reduce CO2 levels and raise pH. Are you storing the media in an airtight container? If not the media will be used up before you put it in the reactor, and it may not change color as expected. Just spitballing now… seems you’ve done everything else. Could get a CO2 meter and find out how high CO2 level is in your basement. If higher than outside air then you have an answer.
