The first tank I ever set up was a 12 gal nanocube. I have since then purchased a 30 gal. bowfront and use a CPR overflow running down into a hole I cut in the lid of my cube so that the overflow goes directly into one of the media chambers in the back of the "cube sump". The sponge on the CPR overflow is the only mechanical filter I use because I have taken out all the chemical and mechanical filter media and replaced it with LR rubble and Seachem Matrix.
The sump is really like a refugium too because I have a deep sand bed, LOTS of LR, and a cleaning crew. I have my heater, UV sterilizer and skimmer down there now and use a Rio 2100 as my return pump.
The show tank is lit with the Hagen GLO lighting kit (2*24W HO T5) during the day and single 24W Florescent bulb for morning and evening. I have 3 LEDs for nighttime. Everything is plugged into a timer.
I utilize 2 powerheads at the moment until I can afford a wavemaker. Currently have a nano and K2 Koralia.
Water levels are all ideal. Though I did have a problem with a power surge that resulted in a strong current traveling through the tank (i have since then grounded the water) that killed all my bacteria. After the surge, ALL my levels spiked: Ammonia, Nitrite, Nitrate, and my PH dropped to 7.8.
Everything started looking really sick...There was nothing I could really do about though. I just purchased some Biospira and some TLC and let the cycling process start all over. It took about 3 weeks intil I started doing daily WC of 10% to get the nitrates back down. Now my water is looking ok.
