House plants? I keep exotics plants as another expensive hobby I can't really afford, and I had to build a greenhouse because my plants were using up all the free CO2 in the house and starting to die. I would maybe plop a couple of bushy plants from walmart down near your tank, but not so close that leaves fall into the water, or salt spray gets on the leaves and see if it helps. Word of warning, never water your plants with water from your saltwater tank. I made that mistake last year, because i used to use water from my cichlid tanks years ago to water plants, and was in the middle of a water change and dumped a couple gallons on one the plants on my way outside and didnt give a second thought till the plant died a week later. The salt will pull the water out of the plant and keep it from absorbing any new water.

I have the same problem and use a gas scavenger on my skimmer. It helps some but my real problem is my basement is loaded with coffee trees and jasmine and orchids and ....
Every night they eat the oxygen and make CO2! Took me a while to figure this out.

Why has no one mentioned buffers? I understand excessive borate but they do work.
Guess kalk makes a lot more sense though.
