Good luck with that 600 gal! looks awesome! cleaning it will be quite a task though lol.
Fortunately, I doubt there will be any gravel vacuuming necessary on my part. Since there will be nothing but a bunch of giant, hoovering bulldozers in there, things will get stirred up so much that it shouldn't be an issue at all. I have never needed to do it in the 180 gallon where these catfish currently are. They get mouthfuls of the small gravel and end up filtering through it. They end up dropping gravel all over each other, and the shovelnose catfish end up wearing on top of their heads for a while. So, while I'd like to go to pool filter sand for them, I am concerned that they're gonna stir it up so much that it will all end up in the sump and eventually into the pump.
As for water changes, they will eventually be happening on an auto timer. Its all part of the system we bought from R1, but we need to hook it up. Till then, it drains at a throw of a level, and then will be filled from the mini water tower we built in the garage. (I think you can see the blue 55 gallon barrels for it in some of the photos in the beginning of the tread.) This is where we store our R/O water. We mix it with tap (and of course prime and acid or buffers) to get the pH, temperature and hardness correct before we change the water. We usually just use a barrel and pump on the floor, but, if we have any problems with ammonia and need to do a huge water change, we'll be able to use the top barrels and gravity for the big tank.
The biggest physical effort is going to be cleaning any algae off the sides. If I start to get tired of this, I just think about JohnPTC's tank and the massive algae magnet and workout that it takes to clean his acrylic.
The 600 in the end will actually be less maintenance than my overstocked 180/100 gallon system. The filtration can barely keep up with these growing monsters. Water changes were getting absolutely ridiculous until we added an FX5 to the system. Those things are awesome!
