Actually, I don't need advice on the rinsing, but more specifically, on the "draining" aspect. I want to disinfect a 105 gallon tall aquarium that I picked up used, using a mild bleach solution as has been suggested many times in this forum. However, when it comes to the part about rinsing "thoroughly," I was hoping for some clarification. Can I simply use my siphon to "drain" the water in the tank, or do I need to actually tilt the aquarium somehow in order to make sure that the water drains completely? If I use the siphon, obviously there will be water left at the bottom, so I'm concerned that it's not thoroughly rinsed, so-to-speak. On the other hand, I can't see tilting such a large heavy glass structure, first because it's close to 200 lbs, and secondly, it seems like it might compromise its structural integrity. Would multiple fillings and siphonings be considered equivalent to being "thoroughly rinsed"?
While I'm on the subject of disinfecting, would it be prudent to run the external filter (sans filter media) while the bleach solution is in the aquarium, and again using the rinse water?
