Manageable maintenance is key to thriving aquarium. I love the simplicity’ of water changes and a skimmer cup rinse. Glad to hear you’re happy with itI got to spend some quiet time just observing the tank last night. I noticed a couple of good sized amphipods running around some rock, the little blue legged hermit crab moved into one of the empty shells I'd put in the tank over the weekend, the corals are all looking much healthier and the 3 astrea snails have been busy eating algae off the rocks. I will be adding a variety of snails as time progresses. The tank gets natural sunlight from 2 windows, one east facing and one north facing, in addition to the dual T5 lighting, so I'll be watching to see if algae growth becomes an issue. At any rate, I am very happy with the tank and am feeling the maintenance will be so much more manageable for me.
