300w I would only use in like a 55g... I use a 150w heater in my 27g, a 100w heater in my 30 long, and a 200W heater in my 44g... So id say a 150-200w is fine for a 36g tank.
Also canister filters can airate the water if you just turn the spray bar up a little. I do that with mine and it makes no splashing noises as long as its further in the water and not spraying really high above...
Also you don't want to skimp out on a canister filter because its cheap and "has good flow" SunSun filters are rebranded filters.. If you look on amazon.com there are 3 or 4 of the same exact filter with a different name. The original one was Aquatop, then it went to sunsun and like two other names.. You wanna know why ? Because its a way for the cheap Chinese company to get out of a warrenty and have **** customer service.. They just switch brand names all the time..
Also look at review of these sunsun and the other brands of the same filter.. Not the new reviews of people going wow I just got it and the filter is awesome.. the older ones where people have owned them for 6 months or so... There are a lot of complaints of cracked canisters after awhile.. motor's going bad, the canister leaking a lot.. That and their customer service is non existant
Its a ****** absolute bare bottom canister filter.. Stay away from Sunsun, Aquatop and the other names under that white filter.
Get yourself a quality filter.. get an Eheim, Or cascade brand. Its true Eheim's are now made in China.. but its still a German Company and the quality is still there. Stay away from Marineland filters or top fin filters as far as canisters go because they seem to have issues with leaks as well.
As for how quiet Canister filters are.. Most people who don't know what Quiet is think canisters are dead silent.. That isn't the case, they are quieter then HOBS for sure but they aren't dead silent.. The quietest filter you will ever buy is an Internal Filter.. One that mounts inside your tank.. Water dampens pretty much all the noise of just about anything so a internal filter is as quiet as filters go.
But a canister being in the living room under the tank, you wont hear it at all.. I have a Eheim 2217 on my 44g pentagon and its in my bedroom.. I can hear it a little bit but its deff much quieter then my HOB was.. I have 3 fish tanks in my bedroom I removed all the HOB on them for Internal filters.. My 10g bowfront I use a Top Fin Internal 20 and its dead quiet I have to literally put my ear against the glass to hear it.. My 27g hexagon I use a Top Fin Internal 40, it too is dead silent.. My 44g pentagon I used 2 Top Fin internal 40's.. But since I have discus I needed more filtration and better control of ammonia so I got the canister.. I can hear it as soon as I walk in the bedroom but its more of a very faint hum noise.. Its hard to explain.. My 30g tank is in my living room with the t.v like yours and I removed the old duel tetra whisper 60 off the tank and put in one of those top fin 40's I took out of my discus tank.. Now I have a dead silent living room and im happy
Personally if you want absolutetly dead dead quiet I highely recommend the Top Fin Internal 40.. If you can handle seeing the filter inside your fish tank, then you will not be disappointed in how quiet it is.. The 40 also holds a pretty large amount of media.. 2 sponges, and a big chamber for Bio media which you can mix take half the media out and put in a fine filter pad above it or put in some purigen like I did.. It has adjustable flow, and a spray bar you can use to agitate the surface, and its pretty inexpensive.
Here isa pic of my top fin 40 in my 27g hexagon.. You can see it, but it really isn't that bad.. No diff really then having a spray bar on top of your tank and a long intake from the canister in the tank as well. I know people might go ooo man internal filters vs a canister sucks... True a canister holds more media.. but a caister filter is still much much much noisier then a internal filter is.. Trust me.. With 3 fish tanks in a 10x10 bedroom you need it to be absolutly quiet and the quietest filters I have ever seen are top fin internals.. The canister in my bedroom is tolerable but I can hear its hum
BTW Petsmart sells these filters
