Tile? Do you have pictures of that? I've never seen tiles used as baffles. Interesting! I would of used the 120 as a display tank but the glass has really bad hard water stains. I tried vinegar helped very little. With a very soft scrubbing pad. I even laid it on all sides and soaked it for 5-8 hours still stained. I went with acrylic as my baffles. I used it in my 29 gallon sump and they worked well. Now I just have to find the ceramic bearings and impeller for my mag drive supreme 2400. Probably going to get that at dr. Fosters and smiths.
