I have a 12 gallon Bowfront with a male Betta and a few other fish, and I was wondering if the water flow is too strong for a Betta? Or is it adjustable? Thanks!
Answer by ChewyAug 12, 2018
This filters contains a flow control valve to let you decide best flow rate which works with freshwater and saltwater aquariums.

can this be used with a Sunsun 704b as a prefilter (is the hosing compatible)?

Great filter for the price

For a really inexpensive filter I wasn’t expecting much but figured it couldn’t hurt anything trying it. Basic lock top canister with everything you need included. Only thing I changed was adding some carbon and quartz tubes to the filter for better results than strictly sponges. The only bad thing is the instruction manual if you have never set a canister up will be difficult.

good filter for dafishes

Have a 20 gallon and this thaaangs perfect, easy setup and adjustable flow rate, 2 different outflow pieces or whatever they’re called, if you’ve never had a canister filter like me then this is a good starter most definitely recommend

Sun-Sun Filter

Cheaply made. However it doesn't leak & is very quiet. Does the job for much less than Ehiem.

Perfect for a nano aquarium.

This canister filter is perfect for my 10 gallon aquarium, it was actually easy to set up I have never had a canister filter and I still managed to know what to do so the minimal instructions were fine, the suction on it isn't the best but for a nano tank it does fine, it's super quiet surprisingly, one thing I did not like is I had to put it in a bucket to hold it up because the pump on it makes it fall over even when it is full of water, other than that it's well worth the money and is better and more customizable than a hang on back filter.

Does the job for now.

Wanted a change from HOB filter on 20 gallon long with clawed frogs. Wanted something with less vibration and calmer water. Bit of a pain to get it working initially, but it is quiet and seems to be working well, keeping water clear at least. The attachments are flimsy, I cracked one of the 'U' pipes trying to get it to fit rim of tank (fixed with silicone) and I made larger holes in spray bar. I do prefer the more powerful HOB type, but the frogs seem to prefer this one. I don't regret buying it, but I don't think I'd buy another one.

Quiet filter

I love this filter! It is a fantastic pre-filter for our bio-tank. We are getting a second one to use as the cleaning filter. Easy set up and no ugly filter hanging in the tank.

SunSun HW-602B Aquarium Canister Filter, 106 GPH

This filter seems to be working much better than my other filters were. The only problem I had was following the directions to get it operational. They were very minimal, which normally is a good thing, but this one I think needed a little more detail. Otherwise I am very happy with this filter.

Bang for the buck !

People expecting this to be an Eheim are clowns. It does exactly what it is designed to do, filters small tanks well. Better than any HOB filter period. I have them all. Including AC and cannisters including Eheim . People critical opf these don't know how to use them. There are man, many uses for them . I have daisy chained them, used as pre filters to big cannisters, filled with carbon tempoorarily, , filled with just floss for clearing cloudy water ... on and on... in this hobby the fun is in how you innovate.... my most stable 20L tanks have these... filled with pummice rock and floss..... the sponges are ok that come with it but take up too much room. The tabs that hold the top on come off, don't let that scare ya, they go right back on easy and never break. has valves for quick disconnect, decent head.... what the heck do you want for 20 bucks? Luv em, have 4 of em for 3 years now.... see YouTube video from Pond Guru....
