I have 3 of those Sunsun canisters, 2 of the largest size and 1 of the size you're getting. Just want to give you a heads up on the one you're getting. After about 9 months, my trays became slightly warped and it was not visually noticeable but just enough that I couldn't lock the top back on. So, it is now useless. Maybe mine was just one of those freak things that sometime randomly happens idk. Anyway, you got it for a great deal and you can't lose with that price. The 2 larger ones have been running for well over a year and has been working flawlessly.
Just a tip on those hoses, soak the ends in near boiling water for a bout a minute and they become super soft and easy to install. Best part is once it cools back down, it'll create a nice tight grip. Also, when you install the hose, make sure you get it to fully bottom out to avoid leakage.
