Hello I am pretty new to the hobby. I did have a biocube for about 6 mo so have a small amount of knowledge. I am looking to buy a REDSEA 170E Max AIO but I did see a REDSEA 260 E max on CL for close to same price but it is well established. My question is being pretty new should I start tank from scratch and start slow and learn as I go or should I jump in to established tank and hope I can learn quick enough to keep everything healthy? I like the thought of starting new but to get a 260e for price of 170E may be worth the risk to get into a bigger tank even know it is used. all thoughts appreciated.
