Benefits of dosing liquid carbon along with pressurized co2

[richieh]

I’ve recently invested in a pressurized co2 system but I still have a big bottle of liquid carbon left. Is there any benefits of dosing liquid carbon along with pressurized carbon? Or can I throw away the liquid carbon?

You could use it up. I find the liquid carbon more useful as mild algaecide. The amount of carbon added, especially versus injected CO2 is pretty small as far as I can tell.

Seachem Excel is not a carbon source, it is not CO2 and it is not a CO2 replacement. Aquarium product manufactures are masters at marketing, and mislead the buyer with many products.
Excel is a mild algaecide that allows users to run slightly higher light with a reduced risk of an algae outbreak. It may or may not help break down protein films growing on plant tissue, allowing plants better access to atmospheric CO2 naturally occurring in the water.

Excel can be used to spot treat, and create plant dips to help control algae.
Excel should be used as an algaecide, not a carbon or CO2 source / supplement.
