Who Gives A Fish Forums

hello everyone,
i'm hoping someone can offer some advice, i've got a 4ft marine tank with a mimic tang in it and i'm thinking of adding a yellow tang to the mix,
i'm really keen on getting a yellow tang as i've got loads of green weed growing on my live rock and i think it would help with that ...

alk's gotta be around 8 for ulns, in my experience. if there's some nutrients in the water, higher alk isn't as likely to burn tips. i've learned that keeping alk stable is key, can't have it bouncing around. had issues with gfo alk swings causing this too.
