Hi, thought I’d share my experience thus far in the hobby. I’ve been keeping freshwater tanks for a while but my 2.5g nano tank is my first saltwater tank. Was looking to do it on a budget and to rely on natural processes as much as possible. The only equipment I use is a low-PAR white dominant light with blue, as well as a blower and heater. My tank is very high-flow and so far I’ve only introduced two easy corals in, GSP and zoas. Both have been doing well and while I haven’t necessarily seen growth, they definitely seem more vibrant. Currently have 2 dwarf blue leg hermits and 3 astrea snails. I used live sand and live rock, as well as bio-spira to kickstart nitrification. The tank has had enough growth of algae and diatoms to sustain my few occupants easily. I direct-feed my coral 2-3 times a week. So far I’m very pleased with my tank, I have found multiple types of tiny critters I cannot identify, as well as things like peaceful bristle worms and POSSIBLY copepods. My main philosophy for the tank has been to take a less controlling approach and a more natural approach, allowing things in the tank to sort itself out. When I had an algae bloom, I added the snails, and now the tank looks better than it did before. If anyone is interested in seeing the state of the tank, I’m more than happy to post some photos. Other than that I would LOVE advice from any other hobbyist running a similar setup without ANY filtration or water changes. Things I’m looking to know would be - what should I add to the tank to boost the overall health of the ecosystem? How can you sustain copepod populations in your tank? Are feather-dusters good for clearing up “dusty water?” Etc. Any advice, tips, comments, and questions about my nano tank are much appreciated.
