Coral Parameter help

isomorphic85 · 07/24/2016, 07:10 PM

Newb here with corals.... I did a 25% water change using red sea's coral pro salt. Several days later I noticed some of the corals closed up a bit... i'm trying to figure out what they are unhappy about.

I have a neon green hammer, various zoas, a trumpet, daisy's, green polyps.

I just tested parameters with read sea foundation pro test kit.

Salinity 32 ppt
Temp 78 F
Ammonia 0
Nitrite 0
Nitrate 1

KH 7.0 dKH
MG 780 ppm
Ca 370 ppm

Any thoughts as to what I should change and how to go about it?

Thanks for your time

Both your Calcium & Magnesium are low, but aside from that everything else looks ok. The links below might help.

Your salinity could be a bit higher (34 to 35ppt), although it's not terrible. Your magnesium is very low and your calcium quit low also.

Magnesium is low. Bring it up to 1200-1400ppm. Do you dose anything?

do you think the levels that i'm at would cause the corals to close up somewhat though?

what's strange to me is that the hammer and the trumpet seem fine... I would have thought those 2 would have been the most temperamental ones...

not currently dosing anything... it's a 150 gallon tank.... only a few corals in there currently.

1 smaller hammer, 1 small trumpet. few medium pieces of zoa's , 1 small green polyps, 1 decent size piece of daisy's.

How long have you had them? Things take time.

I agree with everyone else. Get levels up, especially sg and mg

That's like saying do you think some people would have issues if the air we breath had more pollution? For some it would make life very difficult indeed, and for others it would hardly be noticed. All corals are different. Your levels aren't bad enough to kill anything, but you need to get them in line if you want 'happy' corals.
