Do you already have it or wanna buy it. If you where looking to buy it I would pass. If its already starting RTN then its probably already really stressed out or something wrong with it to begin with and your taking a big gamble that you might be able to save a small piece of it.

yeah RTN is a tricky thing even if u frag off the affected piece chances are other areas will start since its got something really wrong with it to start RTNing in the first place

 

[zanoshanox]

Well, there is only one in my tank that has it, and its on two of the branches (there are probably 20)

 

[murph145]

do u have your water parameters and such so we can see what might be an issue

 

[zanoshanox]

ammonia trates and trites are all 0. Alk 10 mg 1200 phosphates also 0

 

[murph145]

what about calcium??
ur mg is a lil low id keep it around 1300-1400 but not too bad
alk i like mine around 8-9dkh
what about lighting and flow??

 

[zanoshanox]

calcium is 430, for flow i have mag 8 for return, a seio 1100 and a 620. Lighting i have 2x150 w coralife pendants 14k, i didnt like them at first, but i swapped out the bulbs to phoenix's and now it looks awesome.

 

[murph145]

well it sounds like ur doin pretty good to me
i would like i said just stick to aqua cultured and frags from fellow reefers from now jumping into bigger wild colonies can be problamatic at first

 

[zanoshanox]

good advice, thanks

Another question. With acropora frags, what's the difference between bleaching and browning out? I mean obviously the look is very obvious of both but what does each one mean? WHat's going on that's making that happen?

 

[murph145]

hmmm.... bleaching IME is worse than browing out from what ive seen.... i know too much light can bleach out corals im not sure what else causes it but i know lights not the only reason... browning out is usually due to not enough light , too much nutrients in the water, stress...
hopefully someone else will chime in too
