I'm a fool and dropped the controller. The people at the store I bought it from didn't really have a solution on how to resolve this...anyone know how I should go about replacing it?
How much have you googled? Can you contact the manufacturer directly? I found seaporaproducts.com which is just a warranty page (but if you know the logo, you’ll be able to tell if it’s them or not). From there, I looked at Whois.com and it’s registered to GoDaddy. I might be fishing off the wrong pier, though... FWIW, GoDaddy has a BigAlsOnline email address registering the domain name, and they do stock some seapora stuff, so it might be worth contacting Big Al's.
Alternatively, it might be worth trying your local phone-fixing shop to see if they can repair it.
