so i have a 55 gallon tank that has been fully cycled for nearly 3 weeks. in the tank i have 50lbs of lr, 3 damsels, a maroon clown, coral beauty and a six line. i have a seaclone 100 protein skimmer( i know people say its junk but it was free and better than nothin). but recently ive had high amonia levels that wont go away. ive tried a couple water changes but it goes to 0 and right back up the next day. is my protein skimmer that bad and cant keep up with the bio load or am i just missing something.
also i only feed them about 3 times a week.
