This is my first post. Coming from the freshwater side of the hobby I really wanted to keep the look and feel of lily pipes. The only way to get the ADA look is to use glassware, the only way to use glass lily pipes was to use a canister, plus I did not have space for a sump. I got the Hydor 450 for $220. I run 3 trays of sea chem matrix, purigen, carbon and phosban. I clean and replace chemical filtration every week. If you want to see the tank it’s on Instagram “wolfdaddysreef”. The tank has only been up since June but I would not try and dissuade anyone from using canister filter nor would I say that they are the ideal choice for saltwater. They require you to not miss a beat with maintenance.
