tips how you stablize your water!

[Magickiwi]

Tap water for your water changes?
Aquarium near a window?
What's your photo-period?
Have you tested for phosphate/nitrite/nitrate and if so what are the values?
Salinity? Temperature?
Over feeding maybe? It's hard not to spoil our little babies...

If your turbos are dying so quickly what is the cause? That could be an indication of what is causing an issue in your tank. You have a predator tank, I've heard lionfish are pretty messy eaters, not sure about triggers.

If you want an educated guess from people try including some of the parameters I mentioned, chances are one of them is out of line. As a starting point I'd suggest more cleanup crew. More snails, hermits, etc.
