How much PPM do you reckon I would lose off the biowheel on my Penguin
filter?? I have DIY CO2 on a 29gal heavily planted...
PH 7
KH 7

thx
Nick

negligible...if you keep your water at it's highest point, the biowheel
won't actually make much difference... but let your water drop 2" and the
aggitation it creates is more of a problem than the biowheel.... I run a
penguin 330 (30g-60g) on my 29, fully open, and water always stays high...
and it's got pressurized Co2....

I'll be posting pics tomorrow over in the binaries group....

is that better??

Nick, I don't think anyone can express the loss in ppm, there are just
too many variables for any such calculation. The only way to really
know is to turn the wheel off and see what the resulting CO2 level
becomes over a period of 6-12 hours. Having said that, based on your
KH and PH it would appear that you have sufficient CO2 in the tank for
a medium-high light tank. It may just mean you'll need to refill the
DIY CO2 bottle more frequently to maintain a level in the 20ppm range.

Hope that helps
