Hello everyone!
Im having a problem with my SPS. When i add them to the tank, after about 3-4 weeks the tips start dying, begins to loose flesh at tips, looses polyp extension, browns out then dies. i have a acropora Staghorn that is doing well but my Purple prostrata, Strawberry shortcake, lokani, monitor cap, are all loosing their tips and slowing browning out and dying. i have 3 LPS corals and they are doing great. I've checked for pests and found nothing.
here are my tanks specs:70 gallon reef (LPS, SPS, Zoas)
Filtration:
Bubblemagus 5.5 skimmer
Filter sock (change every 3-4 weeks)
Chemipure blue
Rowa phos in reactor
Chemistry:
CA: 440 - 400 (40 ppm change over 20 days)
ALK: 8.8
MAG: 1470 - 1425 (45 ppm change over 20 days)
PHOS: 0
Nitrate: 9-4.5 (4.5 ppm change over 20 days)
Salinity: 1.027
Temp: 78.2 - 79.8 (every day)
LIGHTING:
8 bulb dimmable T5 Fixture.
12pm - 7pm
Running whites at 45% ( 2 bulbs )
running blues at 100% ( 5 )
running purple at 100% ( 1 )
I ran whites at 75% previously but the tips of the sps were dying so i dropped the intensity to 45%. they started browning. I was giving them 480-510 par and now they are getting 360-380 par.
Flow:
1 MP40 ( 80% Reef Crest mode )
1 MP10 ( 80% constant mode )
please help! thanks y'all!
