Hi guys, in need of some advice i have 7 sps frags in a max nano started with mature live rock all doing well except one thats seeming to have a sudden decline.
Green staghorn i received brown two weeks ago now almost fully coloured up.
Birds of paradise coloured up excellent PE.
Pocillopora great PE.
Smoothskin acro coloured up great PE.
Digitata great PE regaining colours.
Purple acropora doing great.
so im stumped as to why one is suddenly showing loss of colouration at the base/90% loss of PE, could it be that this is just one of those corals ?
When changing systems do some tend to go downhill randomly before they perk back up ?
Have had it two-three weeks now & in that time it has retained its colour/PE .. its
parameters;
SG: 1.026 with refractometer & calibrated each time.
Dkh: stable at 8.
No3: 2-3ppm.
Po4: tested on nyos - low to undetectable - 0.01-0.02.
CA: 440
MG: 1320-1340
Weekly water changes of 10%.
So I’m thinking po4 might be too low but I'm unsure as inconsistent test from hobby grade so will be picking up a hanna ULR tomorrow & i doubt its a true zero as im seeing film on glass daily white/light brown.
have had a friend test par with this tank & it showed 220-250 approx at frag height, so im at the point of not wanting to make a lot of changes for one wild acro frag that isnt doing great when all others from what i can see have had no decline & are thriving with alkalinity/calcium consumption going up each day & colouration getting better daily i can see the growth is there albeit slowly .. am i missing something here ? Should i really make any sudden changes that could affect my whole system for one frag, this seemed to happen overnight & only one coral is retracted/showing signs of colour loss around base.
TIA for any insight.
