i cant help to your problem but i just had to ask, how many of those green palys did you start out with 3 months ago? its the last pic in the first post
 
Parameters? Ca, alk, mg, SG, and how do you maitain them? How stable is your temp?
 
About 50% increase

up until a month ago I was only testing PH Alk and S.G. All were pretty stable 8.3 9-10 1.023 to 1.025
Faithfully changing 75 gallons weekly with Red Sea Coral mix weekly was counting on mix quality for other parameters

System is 500 gallon volume with 360 gallons of water
D.I for mix
two large skimmers lots of skimmate
40 watt U.V
aqua pure nitrate filter
nitrate nitrite ammonia 0 always

500 grams Carbon every two Weeks

Added Calcium reactor a month ago Changed to instant Ocean and adding Supplements by hand

Parameters Remain fairly steady as above plus

Calcium 420 ish
Alk is upto 12 ish
starting dosing 30 ML iodine weekly for 4 weeks (no test kit yet)

Calcium Reactor Settings
25 galons per day
150 bubbles per minute
effluent
6.31 ph
calcium 462
alk 16.2

llittle screwup on mag dosing currenlty at close to 1700 but coming down forget where it was to start i think around 900

had these two corals or about 6 + weeks headed down hill immediatly probaby a little too soon but would like to try to turn around and save


another interesting parameter is ORP is about 100 from a high of 220 ish
starting falling about month ago when i removed all mechanical filtration and replaced with two 19 gallon setiment tanks figure it is increased particulate causing the drop
clarity is still very acceptable

i do feed on the heavy side lots of slurry type foods for corals and copopods
btw loaded with pods 1 per square each at night easily on almost everything

tank arrangement

display 75 with 30 bare sump
down to basement to two 19 sentiment tanks
to 75 gallon sump with large skimmer
to 105 (75 + 30)gallon sump from 180 gallon refuge with large skimmer
refuge 40 % live rock 2.5 " sand 3 mh and 8' flourescent amazingly light algae growth i mean all glass has 1/2 " scraped once
most rock is pretty clean
not a huge cleanup crew either 10 each ish snails and hermits

coralline algae steadily increasing about 10 % coverage now

display ATI 48" WITH 4 T 5S PLUS 40 WATTS OF LED

i am glad you asked never really wrote it all down
11 fish damsels etc nothing special, did add a mandrin a month ago, 25% increase in size was pretty small to start

any suggestitions appreciated
 
Do you think it is Lighting??

If So and I already have Most of the tank Covered with A 4 Bulb 54 watt each T5 ATI fixture on Cables. What is 9 good Way of increasing without getting rid of the -3 month old fixture

Any Suggestions
