hi all,
im looking for a little advise. maybe im missing something.
ive been fighting a losing battle so far in my 28g nano tank. i have about 10 various sps corals that are receding at the base and nothing i have done so far has helped. i will go over water parameters.
temp-76-79
alk- 7.5-8 dkh
cal-410
mag-1350
ph-7.9-8.2
phos- .03 down from .06 over last 2 weeks.
nitrate-2
i have 2-vortech mp10's in nsp mode. i was set at about 60% and i turned them up to 100% last week. maybe was lack of flow
i lowered alk from 8.5 to 7.8 over a 2 week period.
i raised the temp from 75 to 77 average.
here is some other equitpment running on my tank.
calcium reactor. ph 7.0 60 drips per min.
bio-pellet reactor with 100 ml of pellets flow at 250gph. ( only been running for 3 weeks) i am tring bio-pellets to see if they will help with stn problem.
phos ban reactor with rowaphos.
aqua-c hob skimmer.
lighting - 150w radium 20k bulb hqi ballast run for 7 hours, 2-18w actinics run for 12 hours. 5" from water surface.
i think all of water parameters are in line. the only thing i dont test for is strontium and iodine. im wondering if low strontium could be causing problems. but ive heard with a calcium reactor normally levels will be ok.
two other things a can thing of that could cause the stn issue.
i have 2 leather corals in the tank. could that cause problems?
was my phosphate to high at .06? had a small hair algea problem.
i only do 10% water changes once a month but i dose trace elements once a week.
i was feeding corals zooplankton and amino acids 2 times a week but stopped that until i can lower my phosphate. i dont think its lack of nutrients.
sorry for long post im just a little frustrated. any advise will help.
