GOSKN5 January 17, 2017 Share January 17, 2017 For the last few months I have had an issue with chalice, leptastrea, favia etc... My tank is mixed reef and has tons of montipora, shrooms, zoas, birdsnest, softies, euphyllias, etc.. all doing fine and growing... But in the last month I have lost 2 chalice, one one the way out.. losing a portion of a nice favia, leptastrea frag, acan enchinata... I also noticed a small spot on my space invaders pectinia.. which I have had for almost a year... My parameters are all stable and in order Alk- 9 Cal- 450 Mag- 1400 Using red Sea test kit and dosing 2 part daily.. Running 4 t5 bulbs with an ice cap ballast and a 150w blue LED strip.. 120 gallon tank.. all corals affected are in the lower half of tank... (pectinia about halfway up)... Any thoughts?? Here are some bad pics of the affected corals.. FTS Sent from my SM-G935V using Tapatalk Link to comment Share on other sites More sharing options...
ann arbor hokie January 17, 2017 Share January 17, 2017 How old are the bulbs? Anything annoying the softies? Link to comment Share on other sites More sharing options...
GOSKN5 January 17, 2017 Author Share January 17, 2017 Bulbs are all less than 4 months.. everything else doing fine... the FTS is current showing everything open and happy.. Sent from my SM-G935V using Tapatalk Link to comment Share on other sites More sharing options...
khh27 January 17, 2017 Share January 17, 2017 (edited) How old were the bulbs you switched from ad did you so them all at once. Are they close it relation to each other or scattered throughout the tank?

ann arbor hokie January 17, 2017 Share January 17, 2017 Neither are problems then. I was thinking off spectrum old bulbs or chemical warfare, but sounds like neither is the case. Link to comment Share on other sites More sharing options...
sen5241b January 17, 2017 Share January 17, 2017 My first thought was a light issue. Did you change anything that could have caused flow to change? Re-positioned powerheads, pumps? Link to comment Share on other sites More sharing options...
sethsolomon January 17, 2017 Share January 17, 2017 My first thought was a light issue. Did you change anything that could have caused flow to change? Re-positioned powerheads, pumps? +1 to this. Also maybe bring the alk down to 8? Link to comment Share on other sites More sharing options...
GOSKN5 January 17, 2017 Author Share January 17, 2017 They are scattered throughout the tank and in different types of flow.. also it's a bunch of softies etc so flow is not overly strong in any one area... Some of the corals were here before the light switch and some after... also went from LEDS to T5 but again only 4 bulbs and a few of the affected corals were added after this change...

Sent from my SM-G935V using Tapatalk Actually just had a thought, are you driving these t5's with an Icecap 660? That could be causing a nasty high par change if you are.

GOSKN5 January 17, 2017 Author Share January 17, 2017 Yes but it's only 4 bulbs and these were all at the bottom of a tank.. approximately 30" below the lights... some even in shaded areas... the chalice is under an overhanging rock...

Sent from my SM-G935V using Tapatalk I would bet your probably getting 300-400 par on your sandbed running 4x 54w t5's on an icecap 660. That Icecap is running those bulbs at 80 watts if I remember right. Also just a side tangent, I would get some fans flowing on the bulbs so they don't get a super short lifespan (5-6 months).

ann arbor hokie January 17, 2017 Share January 17, 2017 Anything added from outside the tank in the last month? Wondering about pests or a new addition bothering them Link to comment Share on other sites More sharing options...
sen5241b January 17, 2017 Share January 17, 2017 ... flow is not overly strong in any one area... Members have seen SPS recede because flow wasn't strong enough? Was flow on the troubled corals reduced? Link to comment Share on other sites More sharing options...
GOSKN5 January 17, 2017 Author Share January 17, 2017 I did change the flow to a pulse from a more constant flow.. I still am doubtful this is the cause as they are located from one tank end to another... Sent from my SM-G935V using Tapatalk Link to comment Share on other sites More sharing options...
surf&turf January 17, 2017 Share January 17, 2017 Whats No3 and Po4? Your tank looks very clean. Link to comment Share on other sites More sharing options...
GOSKN5 January 18, 2017 Author Share January 18, 2017 I don't test for them.. guess I need to start.. Sent from my SM-G935V using Tapatalk Link to comment Share on other sites More sharing options...
surf&turf January 18, 2017 Share January 18, 2017 I have a feeling your tank might be a tad to clean. I see some small fish, but nothing to produce some coral food (fish poo). Whats your skimmer rated for this system? Link to comment Share on other sites More sharing options...

Whats your skimmer rated for this system?I may be leaning that way too.. although softies seem to do well.. shrooms, xenia, cloves, zoas etc... There are 18 fish in the tank.. but the chromis is by far the largest.. the rest all being under 2 or 3 inches... Skimmer is big.. rated for 350 I think... also run gfo, filter socks, barebottom, weekly water changes etc... so it's likely fairly low nutrients... I think I have such fear of algae I go to extremes at times haha.. Sent from my SM-G935V using Tapatalk Link to comment Share on other sites More sharing options...
