Any way to adjust the flow? (Adding a dimmer, maybe?) Turns out it's a little too much for my 55 gal.

Too much? Lol this is perfect for a ten gallon. And you have a 55 which makes me think it's not enough. That's me responding at a 2. Don't make me turn it up to a ten. In all seriousness there is not anything you can do. However, I am still honestly surprised it's too much. May I ask how?

No adjustment but adding dimmer would work though. I wish I got the 400 for my 35 gal to be honest. If it's on the dimmer I'd definitely get the bigger one.

Too much for your 55? I have mine in a 6 gallon nano reef and its great. Anyhow there is no built in adjustment. Non adjustable powerheads have A/C motors, Where adjustable ones have D/C motors. If you tried to put this one on a dimmer it would not slow down and as you kept turning the dial down it would just shut off at a certain point. It MIGHT slow down a little but not much, also this would be pretty hard on the motor. I would just return it or sell it if it's not what you want.

I don't think there is any way to adjust the current :( just plug it in, pop in the filter cartridge and that's about it. Sorry

Yep, that's what I did. The filter tube took up too much of the tank for me. I removed the entire filter assembly (the below-gravel part, the middle tube) and just use a small side-mounted filter, which is more than sufficient.

That's what I have done; because of my hood, I can't raise the lip of the filter very much above the level of the water. I would have liked to be able to; that way there would be some aeration. I do have a smaller model in my 5 gallon betta tank that I don't have supplemental air. Because of this, occasionally I notice a sheen on the surface of the water. If your fish can handle extra circulation, I say go ahead and do it. I've been using a Top Fin pump from a local business that is still going strong after a year

I took a piece of filter sponge and cut to fit for in front of the outflow. I was able to put it under the lip of the top cover and close it over the sponge. It really cut down on the flow. The filter also comes with a plastic curved piece that goes over the top to lessen the water flow. Also, the higher you have the water in the tank, the less the current. What size tank do you have?

read the instruction manual. there will be a section on this. i believe there's a "cap" that needs to be removed first. but it's likely you do not have the drain hose LOWER than the unit so it cannot flow correctly.

There is a flow regulator on top (little black nob with and arrow) try changing it s orientation until you get your desired flow...hope it helps.

Hi, I agree with other comments. I would suggest that you would need to cover most of the base area in order to get adequate filtration circulation for the tank size.

Yes, there's a flow adjustment knob on the pump housing. You'll have to adjust it prior to placing the pump in the back sump. I have mine at the lowest setting and my betta swims around fine. You can also arrange decor or plants in front of the outlet to diminish flow further.

I have 2 koralia 1650 in a 125 (72 inch length) and they are too much for the tank as a placed a partial obstruction in front to tame them down. I also have 2 850 which do not seem enough. For a 55 gallon I would stick with the 850 to 1000 range. I do like their magnetic base and wide column of water generated. I have mostly crushed coral salt tank with some aragonite sand. The sand is a problem with too much turbulence. Just one of the 1650 will transverse the whole 72 inch tank

Can't help you. I still get the same output after about 60 gallons of use. Sorry.

i think 2 of hydor koralia 1500 is too much on the 55 gallon tank. i have a smallest one(550-600gph) on my 35 tank(fresh water), and the size(not power level) a kind of big on the tank, it will bother your view for the tank. i feeling too much stuff on my simple iwagumi tank.other thing is 2 of 1500 maybe too strong to running the water to messed up your plant or decorations. if you want to get 2 of those on it , small one is good enough .

I love the fixture, but our pressure decreased dramatically after I installed it as well. We've kinda gotten used to it, but it's not normal and I really wish I had more pressure at times, especially when filling large pots with water. I hope there is a way to adjust it. My pipes were clean and strong, and my hoses were brand new. It's the fixture.

I use mine in a 20 gallon Tetra tank no adjustments have been needed, I think you might have to go a 300w unit but check the site for their recommendations. Al

I got the 300 watt for my 55 gal. seems to do fine. I rather have a higher watt and turn it down lower. Besides after they get old and don't work as well a higher watt seems to do better. I think a 250 would do the job for a 55 gal

here is too small pot like 2gallon . it is not enough to grow. not excellent. only module and 55gallon reservoir can beused to remake system.

Just checked mine and there is some adjustment possible. Not being familiar with your set-up, I can't say for sure it can be adjusted that much. I'm quite pleased with mine.
