Welcome to my 20 Gallon mixed reef!

I've been out of the hobby for several years, but I've decided to dive in and see if I still have the "Green thumb," I once processed before.

This Aquarium is sort of an experiment in the making. Again, it has been years since I've practiced any of these disciplines, and there has been many advancements in the trade over my "MIA" years.

Primary filtration is provided by a Jebao DCT-6000 return pump with a max flow rate of 1585 GPH, and a SC Aquariums SCA-301 Protein Skimmer, rated at 65 gallons.

Sump size is 24"x12"x12", about 15 gallons provided by Modular Marine. With a 6" area for the refugium.

Refugium is currently keeping Chaetomorpha algae, and around 10 lbs. of Eco Systems Miracle Mud.

System is doing a lot better. Phosphates are still at zero but nitrates have fallen to 5 ppm after adding macro algae, and re-installing the Marine Pure block. Both chalices still have damage from tis
Phosphates at 0.0 ppm after feed Reef-Riods, and Nitrates are still at 20 ppm. I do believe the light is keeping the macro algae a live, and they are removing nitrates and phosphates from the water co
On the 23rd of February I added two different types of macro algae, and two different types of copepods. 3 days later I am having to adjust my calcium reactor. Sunset montipora is encrusting at a rap

Inspiration & Goals

My goals for this setup are to try to grow out SPS corals as fast as possible and improving color, while lowering maintenance.

I have plans to build a 300-gallon peninsula aquarium in my living room, and all practices and knowledge gained from this setup will be applied.
