I did same thing but with the Red Sea rsk300 and my PH. Went from a 7.8 to 8.4 during day and 8.2 at nightI use the BRS In a recirculating pattern on a reef octopus skimmer. Works great. I peak 8.4 and at night I’m at 8.2. Without the scrubber I was at 7.9 high and 7.6 low at night.
My O2 is fine in my tank and I recirculate.I am not convinced recirculating the air from a skimmer is a good option. Although the pH is increased, I wonder what it is doing to the oxygen levels? Taking air from outside reassure me that there is a good flow of Oxygen into the media. I know people burn through a lot of media this way but if you source your media from the right place, cost is not really a concern on small to medium size aquariums. I purchase my media in bulk from a dive shop and it is really cheap.
I have a redsea skimmer. i bought some 3/8 ID tubing and a 3/8 connector. I removed the silencer and connected the two pieces of tubing. The 3/8 tubing slides on the scrubber fittings.my skimmer (nyos 120) intake tube doesnt fit on the icecap co2 scrubber. How did you fit yours?
This is really intriguing. I’ve never heard of that (mixing the CO2 media with carbon). How’s it been working out for you?I have one on each of my tanks (not recirculating - YET) using BRS mini reactors. On one I'm using pure jovert soda lime, the other I added BRS' rox carbon & soda lime and both showing same results raising Ph but the one w/carbon is barely showing color change where the one with straight soda lime is almost expired after 3 weeks.
I’m about to pull the trigger on a scrubber and some bituminous carbon. Seems like it’s got a larger particle size than rox, and a small pore structure which should retain moisture well.So far, it appears I'm getting an extra week or 2 out of the media.
