My 4 year old son's 30 gallon long innovative marine nuvo. All frags at the moment. Tank has only been up since New Years. But its coming along quite well. Lots of stuff from @WWC In there. From the start, I added 2 mp10's, an aqua uv 15 watt sterilizer, a reef octopus classic 1000 hang on back skimmer and most recently, a ghl profilux 4 controller with ph and temp sensors, a PowerBar, breakout box for kessil control, fan controller and a 4 fan ghl unit to help keep the tank temp stable. Ghl dosers, kh director, and ion director will be next on the list. Also thinking of upgrading to ghl mitras 7204's over the kessil a80's
