i love this form, people know so much. Atomizer diffusers look cool. I'll still get good diffusion throughout a 65g(36in,18in,24in) with a ceramic diffuser correct? If I don't I might just hook it up to my 12g and swap out my HM for some nice HC.
65g is a lot to ask from a single ceramic diffuser. But you could try. And if you have a canister filter, you can create a reactor for it. You could always add an extra needle valve and run a line to a second diffuser. Not hard once you understand that everything is just screwed together with some pipe sealant. And everything on that reg is 1/8" NPT threads, so no adapters are necessary.
Yeah, I can confirm that an Aquatek will run an atomizer. When the solenoid is closed, the output pressure increases to 40-50 psi. Likewise, if your atomizer requires more than 30 psi the pressure will just build up until 36 psi (which is what my atomizer requires) and then bubbles will flow. The Aquatek is cheap, but it is capable.
