George usually steers away from asking people "How much?"..most people kind of shrug and say "Enough" or the like. But he did get that figure for this almost all ADA set up. So,for those who want a quick figure of "All the best"..this tells you.
Hi, perhaps yes, however aquascaping means different things to different people. High end equipment is an investment in research, development and increased aesthetic design. You can certainly achieve results with less high end equipment, but the overall aesthetic of what surrounds the aquascape can be equally as important to some hobbyists."Are ADA Iwagumi maximum investment for minimum scape material?"
You lost me with this one Air stones are sometimes used in planted tanks to increase O2 levels up to atmospheric equilibrium outside the photoperiod to offset plant respiration. During the photoperiod, an air stone or whatever method you use for surface agitation and gaseous exchange, will not increase CO2 levels above the 2-3ppm of atmospheric equilibrium...Soon,air stones for plant tanks will make a comeback as people realize they too make misty bubbles of atmosphere Co2 AND more oxygen too for plants and fish.
