I am having trouble with a fire truck montipora - lime green with red polyps if I have the name wrong. Mixed reef SPS heavy 2 x XM10K 250 in LumenMax Elite reflectors over 120 short with 2 x 54 T5 Geissmann Actinic Plus. Lots of flow and everything is doing well except the fire truck montipora. Parameters are good. I use Seachem Reef plus Tropic Marin Bio Calcium and run a kalk reactor.
I have purple montipora, yellow/green montipora, red montipora, blue montipora and superman (purple with red polyps). All are doing well but my firetruck is not. Growth of the red and purple are crazy, yellow is good and the superman is more red than purple with polyp extension. Acros, millipora, pavona, rics, elegance, torch, turbinaria, clams zoos etc etc all happy and growing.
I was told that fire truck was a low light coral relative to others so I have kept it at the bottom of the tank.
It is losing the bright green colour (going dull) and polyp extension is really low. Anybody have any thoughts on light and current requirements (or any other thoughts). I'd like to take an educated guess as to where it should go in the tank. I've moved it a few times but don't seem to be able to figure this one out.
I am a bit old school - I rely on weekly water changes (8% per week), have a refugium with chaeto and a run GFO all the time and carbon when the water changes show a bit of yellow in the bucket. No vodka, no zeovit or anything cutting edge. Tank has been up for around 4 years and came out of a 70 gallon before that.
I believe the system to be in balance - just can't reconcile the low light advice with the results I am seeing but I'm scared to toast this coral.
Flow in the tank is from a Tunze 6065, 6085 and 6101 turned down plus the return (Eheim 1260) plus a few Maxijets buried in the rock. Tanks is not super grown in yet so flow is still good.
