we have over 60 square feet of tank floor space filled with frags and colonies.
we run about 600 gallons of saltwater in our system with over 200 feet of plumbing and a mix of led and t5 lighting.
We maintain parameters as follow
Alkalinity at 9.5
nitrate and phosphate as close to 0 as possible
with weekly water changes between 5 and 10 percent.
Everything is controlled by an apex system and we do our best to maintain rather than chase numbers.
