I have had several tanks over the years but most recently set up a 34G Solana after fighting off some internal demons. Anyway I have inspected and dipped every frag that went in to the tank. I started with "dead" rock that had been bleached etc. Now 6 months later (give or take) I have bubble algae and aiptasia. Now granted there is very little of both and I remove them as I see them but does anyone have a mature tank that does not have any type of nuisance algae or pests? Just wondering if it is possible. 
Edit: Just a disclaimer. I am not saying my tank is mature at 6 months but you know what I mean...
