I'm thinking about putting this on a 30 gallon tank. Good idea or too much current? Is the flow adjustable?

I have a 27GL cube sized tank with this filter. The spraybar spreads out the flow. It is not to much current. With the water forced though the filter media, actual flow rate is half what Sunsun claims. Flow is not adjustable as is but I read online that you can buy a valve to put on the inlet hose to adjust flow.

I agree that this should be fine for 30 gallons. I am using it on a tall 65 and the flow seems almost imperceptible. I should add that the advertised flow rate seems overstated once you throw in media but I haven't actually measured it.

The flow is not adjustable, I have it on a 40gal long tank. It works great, current will be fine for a 30gal. It also comes with different nozzles: single jet or multi-stream. I love this filter. I will definitely by another when I get my 75gal.

Hello there!!! The flow is not adjustable but don't be discouraged... The one i bought i use it on a 20 gal tank and it works pretty good,, I highly recomend it

It should work ok for a 30G tank. I have it on a 27G tank. It's rather weak even with almost no media in the treys. If you have saltwater tank with corals that need some current, this is too week. I know it's rated for much larger tank, but it's grossly overrated. I just got this too:( I'm really regretting it. It's unfortunate, but a powerhead will be needed for me:(Just to be clear, even if you have a fresh water tank, you liken't can't get enough flow to filter the whole tank with this power. Go up a model or 2 and get more power. Other than the lack of power, I do like this unit. I just wish that they have marketed it with the right GPH, and that I have purchased a more powerful one.

It's meant for a smaller tank. I found it made the water too warm and since you can not adjust it, I just took it out. I would try it for a ten gallon but keep an eye on the temp.

This is the first of this style that I have owned. But it is powerful. I have mine in a 55 gallon and it moves the water around good. My tank is fresh water. My answer would be yes but I'm no expert on the subject.

Yes, I am using that on my 55 gal tank, sometimes I even turn it off during the day time.

I am using the 300 watt in a 120 gallon for aquaculture, it seems to handle very well, even outside. I would probably use 2 or a larger one for 300 gallon?

I positioned the spray bar to spray "backwards", directly at the glass it's attached to with suction cups, and it works great. Not too much current since it's immediately deflected by the glass. So no, the output is not adjustable, but there are all kinds of ways you can position the output to lower the resulting current if that's your goal. A betta would be fine in my tank (6 gals) with this canister.

It's probably too big. For 20 gallons of water, a 50-watt would be more appropriate. This is a 200-watt. Mine is in about 80 gallons of water in a very cold room.

I use on a 30 gallon taller tank and it is very bright, really lights up the tank very nice:)

This is very strong on our 125. We run it on the lowest setting or it is too much flow. We run a mixed tank. I would suggest the lower powered one as this is one high-powered wave maker. Love the 10 minute suspend for feeding and it is very quiet. Just afraid it would be too much for a 75.

I think it would be to much current. I run 2 in my 200 gallon Chiclid tank and it works great.

Hi Daniel it will work ok for shrimp like cherry shrimp, also for smaller fish, the only concerns should be if the current is not too much for them, i would recomend a 60 liter (15 gal) aquarium or more, else current is too much, also you can put some wood or stone in the cascade water flow path to decrease the current.

I don't think that you can ever have to much flow in my tank I am running this plus a nano wavmaker and an upgraded pump on a jbj nano.

The flow of water coming out of the top would be too strong for that small of a tank. In a 5 gal tank, the current was too strong for our betta and we had to put a cut water bottle around it to disperse the water flow. It's an excellent filter, but maybe a little too strong for a very small tank.

I use two of these in a1500 gal tank. We are in northern Ga so far is has maintained this tank to 70° I bought a thermostat to control temp works well does not run all the time

I just bought this and it's working AWESOME on a 9gal tank I have. It's very easy to adjust using the up and down arrows on the front. You shouldn't have any problems.

Depends on how much current you are looking for. I have a 55 gallon (48" long) tank and if I set it to go directly across the tank it will gently bend plants on the far side and creates a substantial current the closer you get to the fan.

I think that this would be a bit much for a 40 gallon tank. I would go for a lesser model. it works well on my 55 gallon tank but I would not go lower than that
