Water filtered by peat contains pH buffers other than carbonates, so the
standard pH/KH/CO2 tables will *not* work. The same buffers will interfere
with direct CO2 tests, so forget about a C02 kit also.
Your best bet is to make an estimate based on your bubble rate and look
at your plants to see how they're doing. Even just a little extra CO2
helps a lot. Make sure you have good circulation _below_ the water surface
and that the water surface itself isn't disturbed too much.
