If it works, this product would be amazing.

Anyone have any thoughts? Think it's worth it?

Raises pH an average of .05 to .23 points and keeps it there.



Media lasts 1 - 3 months, depending upon skimmer air volume.

Well, for the most part it sounds like a good idea if you run a massive skimmer and have a high fish load, or have chronic CO2 issues.

However, I don't know that this thing does anything that a big refugium couldn't. If you already have a big active fuge, most likely it's already doing what the CO2 scrubber can do.



What will keep me from buying it is having yet another media to change out .

It's a good idea, I suppose, but for a 0.2 change in pH, I don't think it's worth it.

If you have an open top tank and sump, for evaporative cooling; then I'd guess you'd get something more like the 0.05 pH increase. Also, I think placing this on the inlet of a skimmer that is not air pump driven, will negatively impact the air draw on the skimmer. Finally, I cannot find the media replacement cost on that site, but it must be at $50 or more...

That's incredibly DIY-able. We just need to know what the media is... I'm sure it'd be available somewhere (BRS, are you listening?)

replacements are $30

I'm running one on my tank now, and it did take my PH up about .2 over a couple of days.

I think that is used for dealing with "sloppy" calcium reactors. I bet the media is some form calcium carbonate. If so, the pH would have to be pretty low for it to have much of an affect.

I dont have a calcium reactor yet but it brought my PH from a daytime high of 8.0 to 8.2. Eric from finsreef is my LFS so I've had one on my tank several weeks and was documenting how much it made my ph go up, checking alk and all that but got lazy after a couple of days.

I think it only will do what it's supposed to do if your systems low PH is caused by excessive CO2 in the tank and not by low alk.

Rumor has it the media is lithium hydroxide monohydrate. I took a quick look on Google and couldn't find a retail supplier.

I dont see how that wouldnt drop the air draw of the skimmer pump.

i dont like there claims of skimmers causing a co2 rise in aquariums. co2 is very unstable disolved in water. increasing aeration of the water decrease co2 levels. it has been proven. if u really want to decrease co2 just aim ur return pump up and create lots of surface agitation or add an air pump.

I've seen it happen. My tank is in the TV room in the basement -- if everyone is down there watching TV with the room door closed, the pH of the tank will drop.. due to the increase in CO2 in the room. Many people vent their skimmer intake to outside for just this reason.
