my 29 is torn down. my frags are in a fluval spec v with my 120 w dimmables on about 5% the other 35lbs of rock are crammed into a spare 10 gallon with the aqueon 500 powerhead and aqueon pro 50w heater, dosing ammonia to keep it live. i am ordering a mr aqua 12 long and a mr aqua 17.1 gallon tomorrow and have to decide which one will be a high tech planted and which one reef. I'm almost 100% on making the 12 long a clean and sleek nano reef with my ocellaris until he gets a little bigger and i have the funds to set up the 75 i bought. what do you think ninja?
