Hmmm..10 months in and I don't believe anyone has asked what rock you started with. If it was live you've probably been ready...dry rock is dicey even at 10 months...might be fine...might not be. I would advise against starting off with things like montis and other things you may not want in your coral long term. If you can isolate things then have at it. But...if the acro bug hits you and you've got a monti or whatever taking up a ton of room it may not be what you wanted. Don't just throw things in the tank for a "right now" satisfaction. As mentioned...testing is paramount so get familiar with it because eventually dosing will be needed. I do agree that some.of the corals mentioned are great testers but just be smart about where you put them for future wants/needs
