I did a water change today, it is a Gen-X PCX pump "model unknown", I think I got the GPH on the tank wrong I didn't really get a good look at the pump.

The ph was tested after the ray was dead, the salinity was at 1.020, nitrate: unknown, lighting is just 2 20 watt power compact hoods but they were off most of the time, and gph of the system am not sure about but the Gen-X pump was running at 190gph.

Alright One of my Science teachers just recently bought a Blue Spot Sting ray median size, he only had it for a little over a mouth, It died On Thursday during the end the day, between 2 large pieces of live rock. He was alive during the died and he just died out of no where, he seem fine the day before, no change in eating habits or anything.

This was a very strange I thought for it to die all a sudden, the tank was in a class room setting could it be the noise from class and students, that may have stress it out and cause it to have a sudden death?

photos of the aquarium.

also after when this problem have been solve or concluded

any recommendations on a tank occupant, that's hardy and can stand the settings of a classroom that wont get too big for a 180gallon aquarium.

slightly used 55 watt pc bulbs 5.00 each

What kind of K are them?

is it 8000k and Straight pin?

Am looking for 55 Watt P.C. Bulbs 6700k or 10k but it has to be Square pin

thanks
