I should add I have a 425 and a 240 plus the 240 flow from the filter pump ... If you don't want corals you may be able to get away with just a 240

I don't think it will move your sand unless you point it right down at it it should be fine just pointing out but if you are worried about it go with the smaller one

I had 2 of these in a 30 gal regular with no problems at all so I would go with this 425 just don't point it directly at your sand lol but hydor's have a very nice spread on the water flow so I doubt you would have any problem

Point the pump at the glass, not down and that should help. .. I have 2 on my 29 biocube and have no issues.. A 240 is not enough in a 20 gallon if used alone so I would at least pick up another 240 for the opposite side .. Do you have enough rock or is the flow getting obstructed down ? Mine are placed mid level in tank and again are pointed at side glass

I have mine in a 36 bow front it does nothing byt create great water movemebt my clowns love it and my sand stays put just fine make sure you blow it going from bottom uowards a little should have no problems

Turbine spins very fast, I hope people don't try to block it as it keeps things within operating temps. Duster already gets quite warm with extended use.Also as of note the fine tool attachment adapter has a 'blow hole'. I wanted to block it at first, but it regulates the pressure out of the tiny nozzle so it doesn't get overloaded. Don't try to block that either, it blows plenty strong without covering it up.

Yes, this circles in a 360 motion like a wheel. Depending on the strength of your pump, it may be "too much." If you have gravel, it may not move the gravel, but it definitely would stir sand in a nano tank. Also, keep in mind it is the size of a half-dollar, so it will take up space in a nano tank. Hope this helps.

Unless you live in an unheated igloo, I suspect it may be more powerful than needed. Also, it's pretty big for a typical 20g tank, and has to be completely immersed, so might not fit.

Yes. I've been using mine in sand for a year now. No issues. It look a little bit of adjusting during setup but has performed excellent since day one.

Yes. The blower has a variable speed option if your gravel is very small. But even if it didn't I don't suspect it to be a problem. I have a gravel pit and haven't had any problems as of yet. Hope this was helpful.

It sucks up a little bit of sand but unless you bury the end in the sand then the suction isn't strong enough to pull it out of the tank. I actually really like how it cleans out waste from the sand and allows the sand to fall back into the tank. My best results are when I hook the vacuum up to a garden hose turned on all the way, by the time I'm done it looks like I have new white sand again in the bottom of my tank.

Depends on the surface area your working with. Please keep in mind it is small unit relatively speaking. If you are working to sand a smallish area, it is acceptable, it's not meant to cover large areas given its size and power. I hope this helps!

this power heads are great for that big of tank i believe i would use about four of them they blow much easier then the old ones , you can direct them much easier also.

i am assuming u r doig a nano reef if a regular powerhead will do the trick try aquatop 400gph should be more than enuff power to eliminate any and all dead spots...make sure u get an aquaclear pad i get the 110 pad and cut it to put over theintae of the power head that will keep things out of the intake strainer and yes u couls ude it but 800 gallons per hour would be to much in my humble oinion

I have the 306 model with a 3 foot long 38g and I have to turn off some of the flow, since the water current is so strong it blows the sand to one side. Now, in theory, the larger the bio-filter area in the canister, the better, so just use less flow.

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

Greetings, for a tank of little ability I do not particularly recommend it. will have too much turbulence, like a hurricane.Look for a more consistent eg 240 Koralia nano.

I agree with the other answers. Mine runs for approx 20 secs on a timer. There is only a top highwater float and not a "shut off float" at the bottom. Your pit is decent sized so there is a lot of water in it circumference-wise to empty in 20 seconds. It should not matter whether there is still water in the pit and indeed you don't want the pump to be running part of the time as dry. I'd rather have a little extra water than not enough such that part of the 20 second run time is dry. 4 inches in the bottom seems just fine. When it fills again the pump will turn on again.

You can just plug it in and it goes. It can be hooked up to a timer or wave controller but doesn't have to be. I have it in a 29g and it works great. Think it will be fine in a 20g.

Looking for the same thing for a different reason. I'm looking for a way to use those small portable tanks with one of those propane-powered weed burning torches. Would be much easier to walk the burner around with a portable tank attached than to drag around a 20-lb tank. Do any of you readers have information to help all of us with our situations? Thanks in advance!

this powerhead works really well. just depends on what animals u have in the tank. I have turltes. they're constantly knocking it off the glass so in hindsight I would get one with magnetic mounts instead of suction. other than that the pump works well
