Re: [APD] re: CO2 probe and in-line heater
20 pound sin 5-6 mos., isn't much diff than my 10 pounds
every 3 months and I have a much smaller aquarium.
If you're only causing the water to ripple rather than
splash and bubble, I suspect that isn't having a big
impact. I think that rippling the surface doesn't make
much diff; it's breaking the surface and mixing the air and
water (downspouts, drains, trickle chambers) that have the
big impacts on CO2 levels. Even without ripples, planted
tanks generally will have reasonably good watercirculation
(and maybe strong currents) so plenty of water has it's
turn at the water surface without or without rippling.

Cryptocorynes seem cryptic? Worried about meltdowns? Can't tell a C. wendtii from C. undulata? See 'Crypt'master Jan D. Bastmeijer, host of The Crypt Pages website, at The 5th AGA Annual Convention. Details/Registration at www.aquatic-gardeners.org & www.gwapa.org
