ok, I ordered a 150 tank, I took the plunge! Selling my 110 tall I'm gong nuts trying to figure out which filter system is better for my needs. Here's what I know so far...I will have 175 lbs of LR, a black moon sand bed of about 1" maybe 1.5", and the tank has 2 overflows, I have a decent amount of fish I will be transferring after QT each one individually (I had a couple of ich breakouts and I will be keeping them in the 110 until I an add them to the 150 over time) a vlamingi, a pink anthias both about 5" or so, a yellow tank, 3 perculas, and 2 firefish. I will keep my two linkas, and serpent star, I will also have my clean up crew of snails and crabs, cleaner shrimp 2, and 2 peppermint shrimp. I will have soft corals mostly, but will delve into everything except maybe not SPS I haven't decided that for sure yet. I am wavering between a berlin system with an added refuge (or not), and the ecosystem w/ the miracle mud. Which one in anyone's experience is better based upon my tank description? I have the wet/dry with bio balls and havened been happy with it for awhile so I will switch to one of the 2 systems mentioned. If berlin then what brand has been great for anyone?And what brand skimmer if berlin? I have a headache from so much reading and confusion that I can't think no more! :?
