Gipper:
The spray bar design is perfect. I use the same type.
You can scuff the pvc up good with very course sandpaper and cover it with java moss etc to hide it or simply have decore and plants hiding it.
I have mine sitting on the gravel's surface.
Wet/dry filters remove no more CO2 than other filters if set up right.
Most of the CO2 lost occurs in the overflow due to splashing etc.
See George's Booth's, Steve Dixon and my discussion of the APD or elsewhere about that. We all use wet drys and never have any issues. Don't inject air into the biotower etc. The biotower does not degas the CO2 if sealed. It' actually fills with O2 during the day and with CO2 during the night.
But this is mainly from the plant's action, producing O2 in the day to excess levels above 100% and the bacteria in the sump producing CO2 as they use the O2.
CO2 is cheap and easy to dose, even if a little was removed.
The surface skimming takes oly the tank water with the least amount of CO2 into and the then returns only CO2 enriched water since folks use the CO2 reactor in the sump which feeds directly into the return pump's intake.
I can cover all the wood with plants etc but it's not the design I have in mind.
There's plenty of plants in store as it is.
Recall these are empty non planted tank right now
That will change.
