Gtreef's 12g Fluval Edge

[Stones]

Sorry to hear about your loss. The one downside of these tanks with the covered glass top is that it's diffcult to really generate any surface agitation except where the HOB filter dumps back into the tank. In FW this is a good thing as it makes it easeir to keep CO2 dissolved in the system for plants but for a reef it's actually quite detrimental.

Have you considered running some type of nano skimmer on the tank in order to help with aeration? Not sure what options you'd have but a small airstone driven skimmer could likley be incorporated somehow.
