    Fish don't survive long in my display

    Yes my glass top covers the whole tank front and back. I wonder though if gas exchange is a problem, why would my fish still do well in my DT for as long as 2 months?

    Fish don't survive long in my display

    Yes my glass top covers the whole tank. I am using overflow as well as two vortech mp40 so flow and gas exchange should be good.

No direct sunlight in the...

    Fish don't survive long in my display

    I don't know why my nitrates is on the high side but the turbo snails, hermit crabs, and crab that I am keeping in the DT are all doing well and alive. I am even using a phosban reactor and running a refugium with lights on at night when the lights of my DT is off

I started running a 210g display to keep saltwater fish only since March 2014 (last year) so my tank has been running for just about a year now. I've been losing fish all along and to this date, I only have about 8 juvenile size fish in my...
