too little light....or too much light

[nycfishy]

have had these frags in my tank for about a week now and noticed the tips of them are dieing/bleaching. The are in a rsm130 with led lights. Have the lights turned up all the way. Rest of the tank looking happy Does this happen with because of too much light or too little? or is it something else?
Water quality (ammonia, no2, no3 all good, 0,0,10ppm) phosphates @ .09, pH 7.9 (bit low I know, will start using kalk next week), Ca @410
have mp10 for flow, upgraded rsm pump and running GRO/Carbon in canister

Those are growth tips. It's a good thing

 

[nycfishy]

so should be happy and not worried? I had turned down the lights to 50%, guess I should put them back to full power where I had them

Leave it 100% as it was, unless bleaching occurs (which it is not). Read about the differences between bleaching and Tissue necrosis. This is an important difference to know.

any goods links with pics on the difference between growth tips, bleaching and RTN?

you should work on lowering your phos to under .05 . phosphates @ .09 is a little high.

nice little birds nest tho.! looks like its growing well and happy.

also here is a thread that is pretty good with explanation on RTN, bleaching and STN.

Like Jackson said tips are growth. If it was a burn which it's not. Alk plays a role in that. So watch Alk with SPS. And like Rob said watch Phos level. Don't chase your PH its ok. Open window or air from outside to protein skimmer can bring it up a little. But don't add anything. Your tank seems to be doing well.

thanks for the advise guys, working on getting phosphates down. Just started running GFO and it seems to be doing a good job dropping them (was @ .15 last week).
Feel much better those tips are from growth and not from me doing something wrong. when the tank was last up I had horrible luck with SPS

There doing Great as I can see from the way they look just keep the cal and alk up and they will like like the mother colony they came from.

thanks dude. I'll be happy if I can get them to be half as nice as yours.
