Red, raw genatilia - I'm incredibly worried! HELP!

[CaitlinAnn]

Zilla and Ghost. Next goal will be to help decrease the water flow so it doesn't bother them, though Zilla doesn't seem to mind. Also fattening Ghost up a bit..he's lost some weight. Finally have nitrates and nitrites at 0! I finally feel like I can breathe and that they're doing ok.
