Gtreef's 12g Fluval Edge

[gtreef]

My two clownfish died this evening Thinking low O2 did them in, all other parameters were good, Ammonia 0, Nitrite 0, Nitrate 5ppm, temp 78, salinity 1.024... sucks a few shrimp were in distress as well but have survived, I did a 25% water change and didn't fill tank all the way.

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.

I use a Vortech MP10 powerhead in my 6g edge at the lowest setting but I run it pretty high up to get some water surface tension to get as much oxygen as possible.

Do you leave a bit of air at the top of your tank to help with O2?

No. I keep the water line pretty high so that I can view everything top down.

Had a look at your tank build on nano-reef, very nice! do you have a thread posted on here or there showing what it looks like now?

Got a call from my friend at the LFS and he gave me two black percula's for free! Gotta love having friends in the fish business They are soooo nice, and looking very happy and eating very well. I will post some pics soon. I have a HOB skimmer on it's way as well, yay!!

I have a thread on nano reef and RC.

Not much to update. I just added a bluespot jawfish and anemone. I had a true perc clwonfish hosting in it but the bioload was too much for such a small body of water so I took him out.

Making it into a reef was just too much maintainence so the frags that were added were also taken out.

It's just a jawfish house at this point. I might get motivated again in the future and add more corals, who knows.

Yes, I have left a cm of space at the top of the tank and have the powerheads directed near the surface to help stir in more O2. I think a nano skimmer is in order when I save up more cash. The initial startup of this tank has to be paid off first. I guess I shall work out the kinks first before attempting any other livestock.

I have now added 2 captive bred black percula's. They have been in the tank for about 2.5 weeks and doing well. I have on order a remora nano skimmer and LED lighting! They should be here in a few days.
