SUNSUN 303B canister filter review:

You find the great perfection of this work performance when you can set up perfectly. Most of the people set them up wrong.The Sunsun 4-Stage External Canister Filter with 9-watt UV Sterilizer is a great buy for the money. Thn SUNSUN Built in 9 Watt UV sterilizer and it can kill algae spores and bacteria, promoting crystal clear water.

Set up:

All filter pads must go on the bottom tray.This only comes with 3 Medium pads in each tray like Coarse, medium and fine filter pads(none on top). And then your bio media in the middle or top. (Bio media not included) I just fill the top 2 with bio media.

The intake tubes on the trays have spiral walls to circulate the flow around the UV tube. The spray bar is made of cheap plastic but it works just fine, just be careful when putting on the flex hose to the U shape fittings, you may bend them. The intake tube is also cheap plastic and has an optional surface skimmer that can be capped off if you don’t want to use it.

Priming:

Once you have everything set up perfectly and before you close up your Sunsun.  Engulf your take water into your filter and fill it up to the top of the trays.If you don’t do this, you will be hitting that prime button all night.

Once its filled then you can close it up. If you put too much water in it, you might get water everywhere when you close and latch it up. Then you push the primer about 3 or 4 times, turn on the power and your done. It will be loud at first because of all the air in the lines.

Frequently Ask Questions:

would this work for my 40 gallon goldfish yank or should I go higher?

We have it in a 40 gallon turtle tank right now. So it should work in your 40 gallon fish tank also.

Is there a pump included, regardless of which one we purchase?

It has a good strong pump to pull the water through the filters and uv light. We use ours on a 75 gallon aquarium and it does a good job.

Can I replace the 9 watt uv with a 13 watt?

No, you can’t. For two reasons: 13watt lamp is longer, so it won’t fit in the same quartz sleeve. 2nd: the UV ballast is 9w, it might light up a 13w lamp but you will damage the ballast in very short period of time.

Do you need protein schemer with this?

If u do saltwater u need a protein skimmer or do a fish only tank using hydroponic hydrogen peroxide to keep your fish happy and your tank spotless.

Dose filter come with Filter pads?

Yes my 303b came with pads but no other media i bought 1 gallom of bio-balls to fill it up
