I was bored today so in an effort to combine some equipment I build a Barr Reactor so that I can remove a powerhead and tubing and get rid of the Rex Reactor I have sitting on top of my tank. I added the sponge filter the other day and will add a second one soon. Plan it to get rid of the AC 110 HOB eventually having the two sponge filters and maybe a couple small powerheads. I tested it and it seems to work but only for a couple minutes. My CO2 kicks on soon and lights at 4:30 so I'll see what kind of effect it has on the drop checker soon. I didn't adjust the CO2 level yet until I see what happens.
Here is a shot of the Barr Reactor, this is not the spot it will stay, I'll be moving it to the back corner and hide it behind some plants....and don't mind the micro bubbles, that's actually from my filter, I need to top off a little water.
