Filtering through peat moss would lower your pH. That's what a lot of discus-keepers do. We don't in the Lower Mainland usually because our pH is low and our water is "soft".
Also, as cale262 stated, reduce your overall surface tension and flow in the tank to allow the CO2 longer time to work in the water column before being dissipated into the atmosphere.
A lot of us locally are using Metricide instead of CO2. Its a concentrated form of the "plant food" Flourish Excel (double the strength) that is used to sterilize stuff in the medical field I believe. There's a local source for Metricide and its about $20 for a gallon which will last a very long time. I manually dose Metricide twice a week and the plants grow like crazy on it.
