240 total volume. 18 months in.

very few. but i've been lucky to find a couple of knowledgeable experienced ones to help me.

 

upgraded to 400 watt halides today. and my sea hare that i thought was dead showed up alive and well. a good day.

 

very active and beautiful tank! What do you use for filtration?

 

i have a 90 gal sump with a refugium containing live sand, and 80 lbs of live rock, as well as chaeto and mangroves. there's 320 lbs of rock in the main tank. probably a lbs of activated charcoal in the sump with some phos. also running a uv sterilizer, a massive skimmer, and a large clean up crew consisting of hermits, snails, shrimp, and crabs. banded and diamond gobies take care of the sand. i change 30 gallons per week of water.
