I have just ordered a fluvial 407 for my 75 gallon tank. THEN I measured the space in my cabinet, and i only have about 19.5" of clearance under there. Also, the rim that goes around the perimeter is only 17" above the storage shelf height. Fluvial website says the canister is 19.3" high, so i'm sure that will be too crammed.

Amazon says the Sun Sun filter is 17" high, so i'm hoping i can go this route. Can these tubes start to bend down somewhat after leaving the filter and still work properly? does anybody here have one of these and can confirm the height from bottom of canister to top of the black tube connectors?

Thanks,
Ridley

I have a fluval 307. It is sitting in my cabinet with a roof space of about 5.5 inches and I drilled two holes on the roof to run my hose through the cabinet. This roof room is just nicely reaching its limit when doing maintenance for the canister. My fluval 307 measured at a height of ~13 inches (canister body only). It have this adaptor for the hose connection protruding by ~2.5 inch. Hence, there is about 2.5 inches of space for me to pull out the adaptor when I wanted to take out my canister for cleaning. Hope this helps.

That helps a ton, thank you so much! does the round piece immediately below the red nozzle allow you to change the angle of the tubes as they approach the canister?

if so it looks like i'm going to be ok with 17" of height -

Just a little food for thought - I am running a Fluval FX4 on my 75g tank. Vertically I have about the same clearance as your setup. Part of the reason I went with the FX4 was for increased circulation within the tank and the capacity to handle a higher bio load.

My Fluval 407 sits at about 19.5" (so 19.3" is right) not including the hoses. If you only have 19.5" of clearance, I don't think it would be possible to use the 407. If you have 19.5" of clearance to get it inside the filter, but once in the space is larger, you might be OK.

Edit: For less than a 407, you can double up on a couple of SunSun 303b's - which is what I'd do, in your shoes, for a 75 gallon. My 75 is filtered by a single SunSun HW-3000 and I wouldn't purchase this filter again. It's 90% good, 10% bad. The bad parts are that the flow isn't anywhere near the stated maximum - standard for most canisters, but I feel this model is particularly overrated in terms of GPH, and the priming method. You need to unscrew a cap on the intake side and fill the hose with water. It's quite effective! But it also prevents you from using aftermarket intakes such as a lily pipe with skimmer. It comes with a surface skimmer but it's too weak as it will suck air into the filter unless you turn the flow setting down considerably even with the bottom vent open full bore.

I ordered a Sunsun 304 b. Amazon says it is 17” high, so hopefully it will barely fit
It's a good choice for an affordable filter! Truth be told, I wish I got one instead of the 3000. Keep in mind it uses 3/4" hoses in case you want to use a custom intake or output, or plumb anything in line.

Well, the SunSun 304b was pretty close to 19” with the nozzles that receive the tubes, so it did not fit.
Do you have pictures of the stand and what it looks like inside it?
I have 16.75” of space from the interior shelf to the back rim

I ordered a Eheim 2217 from amazon so i can return it if needed (plants are being delivered soon so i need to get this thing up and running). thinking about Fluval FX4 as well, but don't want to blow my school around.

i don't want to get into a sump if i can help it, but thanks for the advice.

You were right about the fx4, Fits snugly In the cabinet and that’s what I’m going to stick with. Only had to buy and return 3 other canisters lol!. Thanks for your help!

I would place the output in the middle, right up against the brace, and have the nozzles facing angled to the left and right, then put the intake against the brace as well but on the other side of it. That should give you a good flow pattern and if it's still too strong for your fish, simply adjust the flow on the output valve that hooks up to the canister lid until desired flow rate is achieved.

Not a problem. FWIW, one of the nice things about the FX4 is during a water change you can also dump out most of the water in the filter thru the drain at the bottom - very handy. Something I am not happy about with the FX4 is the impeller shaft seems to be very brittle - does not take much to break it. Would suggest some silicone grease on the end of the shaft where it goes into the rubber bushing (in the filter housing). Then when servicing the impeller, make sure you pull the motor housing straight out (don't wiggle it side to side / up or down).
