I set up this 20 gallon long in the beginning of this January. It's been running smooth but my first fish got ich. I had a clown and cardinal but he died and the clown survived. Now he's in a 10 gallon quarantine with a filefish, both being treated for past 3 weeks, 3 more weeks before I add them back to DT. Gonna start quarantining all new fish, but I can't quarantine corals no room/money to set up another tank. Is this ok? Should I expect alot of pests once I start adding more corals? Should I dip them in "stuff" or something? Also, how should I get coraline algae to grow? I read seeding the tank with frag plugs and stuff will do it but im not dosing anything so will it have enough elements in the water to grow? (I plan on keeping this tank softies and a few lps) Thankful for any knowledge or advice you guys might have, thanks
