Lifegard 4.1 AIO Pico


Recommended Posts



I originally started this tank in a Fluval Spec III in 2020 and was moderately successful until the tank had an unexpected and still unexplained decline in Dec 2021. I think it was chemical warfare with a dying BTA but all that to say I never figured it out and then rebooted the tank in the Spec III on October 3, 2021 with the existing rock and clownfish. I then added the Toadstool and Zoas and things were very stable for a 6+ months less some coral frags that didn't make it, like some SPS birdnest. Then the Spec III developed a leak in the rear, bottom part of the tank and I moved everything into the Lifegard 4.1 as I liked the AIO design, the profile of the tank, and it was available at my local fish store for a very reasonable price. The tank has been in its current form since then and I am slowly adding corals again.



Tank is sitting on a small piece of furniture that originally had 4 drawers that I modified to be 1 drawer with a generous area underneath for electrical and ATO storage. The drawer holds the day to day maintenance supplies like the refractometer, tweezers, etc. Underneath storage has enough room for a gallon bucket of RODI top-off water and the electrical components: Power cords, power strip, light timer, Inkbird controller, and a Reef-Pi.
