>>5002847 (OP)Go for it! Starting small can be harder but itโs an easy way to get your feet wet and start learning about the hobby. Start simple, nothing fancy. A cheap $20 10-gallon Petco tank, Chinese black box light from Amazon for $60, and HOB filter should have you good to go for under $150. Iโd recommend live sand and live rock if you can hash out the cash. Personally I do 1-1.5 lbs. of rock per gallon of water. Once youโve got it all setup, add some hardy soft corals such as leathers, zoas, GSP, or Kenya trees. Wait till itโs cycled to add fish but if you go all live rock from the start you shouldnโt have issue keeping hardy corals from day 1. As for water, buy a 5-gallon jug and just get RO or salt premixed from your LFS. I have three low-maintenance tanks, pretty much just feed and top off.
