| One thing I noticed when adding a TT in addition to the existing submerged filters it the first week the pH climbed up from 7.4 to 8.2 in a week. Stayed there for a few days before settling in at 7.8. I think degassing the carbon dioxide raised it. I also get a lot more suds now than I use to since I added the TT. I have a constant flow of tap water that would overflow that use to get rid of the small amount of suds but too many suds to keep up with. I might have to add a foam fractionator. |
