Two Little Fishies CDX Carbon Dioxide Adsorption System Information




Many aquariums suffer from low-pH issues. Sometimes it`s the carbon dioxide that accumulates in the air in closed buildings that won`t let the pH of your aquarium stay up. TwoLittleFishies have the solution: It`s called CDX, a Carbon Dioxide adsorption system.

Simply install CDX media in a PhosBan reactor and connect it to the air intake of your protein skimmer with the CDX Adaptor. The CO2-free air injected into your protein skimmer drives off the excess CO2 dissolved in the water, so the aquarium`s pH rises. Happy days are here again! A 750 ml jar will last about 6-8 weeks on the average 50 - 100 gallon reef aquarium. You can tell when it is exhausted because it changes from white to pink.

Boosts pH

by
Reviewers Rating Excellent!

Experience Level: Intermediate


Comments: My pH ranged from 7.9 at night to 8.1 in the day. I have a tank in the basement and during the summer and winter the CO2 levels from the AC and heating unit were elevated. I was having issues keeping acropora corals. People kept telling me that my pH was OK and it wasn't that low. I used this in a canister and after a day or two(give it some time it doesn't work instantly) my pH is now around 8.3. All of a sudden my corals all look a LOT better. I doubt it is just a coincidence. Don't let people tell you pH isn't a big deal in a reef tank. I wish I had tried this sooner.

Comments: Product is easy to use. I made a simple DIY canister with an empty jar and some microfilter pads, but a media reactor would work great too. My tank is in a basement where a lot of excess CO2 can gather, especially in the winter with the house closed up. The pH on my tank generally ranged from 8.0 - 8.1. Now it ranges from 8.2 - 8.3.
