I too had concerns about using my DIY
'd wet-dry with a "pop bottle" co2
system, since the "pop bottle" system produces so little usuable co2
I wonder if having high pressure combined with a controller of some sort would be able to better contend with any loss incured by a filter that generates a lot of turbulance (like a wet/dry is designed to do). Would it just use up your supply faster than if co2
loss was a minimal levels?
Would covering the wet/dry, to stop air from freely circulating "over" it would eventually build-up a co2
blanket inside the filter, reducing the loss? I wonder how that would effect the aerobic bacteria, would they get enough oxygen just from the water?
Do you really need 500 watts of heat? ... I like overkill heating because I live in the "cold north", but in Texas? I guess heaters are one of the least expensive items for an aquarium, and those titanium ones really look nice.
I concur that you should have about 3 inches of substrate ... in a tank that size, you'll hardly notice it! ... 3 inch substrate in a 10 gallon ... that's something you notice
According to the Schultz website, Profile also comes in 25 lb bags ... I wonder, assuming the larger bags could be found (or ordered through a hardware store), if the price per pound would be significantly lower?
