Poor Marty (our betta) has contracted a case of pop-eye lately. (Scroll down the page to find the entry). I'm currently medicating the tank using Maracyn Two (an anti-biotic), so hopefully it'll clear up. FOrtunately it's only in the one eye, so with luck he'll return to normal soon. The cause? Poor water quality, of course. I've been neglecting testing the water recently. Last night when I did, I realized the nitrate level in the tank was beyond acceptable. Yipes!!!
