If a 75-gallon tank had only 35 gallons of water in it, how long was the plexiglass lip you added. But wait---are you the person who posted pics of their Aquaclear 70? (Sorry, I don't have time go back and look). If you are, I remember saying that the AquaClear 70 was pushing it in a tank that big. (If you're not, I apologize for being mistaken).
OK, let's forget the Aquaclears. I used my XP3 for 2.5 years. I stopped using it because I had it on the floor next to a stock tank and realized I was going to wear it out using it that way (it had been on the floor like that for over a year). If you're sensitive to noise, you don't want to get one if you can't put it on the floor under the tank. When I used it as was intended, I couldn't hear any noise. The only time I had minor problems with it (never a leak) was because of something I did (put the impellar in wrong when cleaning, not having the media baskets set in properly, etc.).
As for special instructions, the manual says the filter should be 24 inches below the water level. If you don't want to hear any water, keep the spray bar or spigot (your option as to which you use) under the water line.
I remember only 1 poster who had a leakage problem with the XP3, why, or whether it was defective, I don't know. On balance, the people who've bought them and like them is overwhelming greater than those who have had problems.
Perhaps someone who uses a canister other than the XP3 (or 4) will be able to give you a different perspective.
