2 keep trying to grow sps or go nps?

[drd]

My nano 28 HQI may be to nutriant rich for sps leaving me to go to nps/lps corals as they go in and bleach out in 2 weeks time
the water peramiters are almost perfect ph 8.3 kh11 ca 425 mag 1350 no amonia or nitrites or nitrates the blue ridge is growing and doing well so why no acros or pociporas?
temp is 77 does have a protein skimmer and a phos reactor on the tank too
so it is a problem and now one has an answer to it
but it is belived to be neutrent rich waters, as the tank gets water changed 25% a week, nsw is replaced and top off is ro/di

What about your salinity and flow?

How do you know your test kits are accurate? Have you tried any others to double check?

 

[drd]

salinity 1.022
tests have been checked at a local lfs to same results

 

[slant77]

I think most with sps go for 1.025 or 1.026

 

[drd]

was at that and lost a lot of them
1.026 salinity and lost them too

i suggest you dose your tank with a few punctuations and capitalization eventually all will balance out your acros will love you for it some of your fish too

calibrate youre salinity probe and make sure that 1026 is 1026 check too make sure your personally i wouldnt use nsw and would rather make up my own salt mix you can get a lot of non desirable things in nsw

calibrate your hydrometer. my hydrometer reads at 1.021, correct reading would be 1.026

 

[Gomer]

hygrometers are temperature dependent make sure that you calibrate at the same temp as your tank you are better off using refractometers you can get reasonably priced ones from a few online sources
