Dennerle Snail Catcher - for Aquariums, with Telescopic Handle

I normally don't write reviews, but I absolutely have to tell y'all, this works SO well. In just a few days I have greatly reduced the population of bladder snails in my 55gal. I just roll it up the glass whenever I see them and tap them into a jar. It also works with little egg clutches if you're careful enough to not lose it in the water column. Doesn't really work in decor, but it's no big deal since they usually end up on the glass eventually anyways. I do wish it was a bit longer but other than that, love this thing.

I love this product. We had a serious snail problem and this has been awesome. It’s super easy to use. The only drawback is it doesn’t really have a great way to drain the water from the snail trap but certainly not a deal breaker. Overall, very pleased.

I have a serious infestation with trumpet snails.. it wasn’t bad at first so I didn’t mind… AT FIRST.. then snails were EVERYWHERE! I have several shrimps and some fry in my 37 tall tank so using any chemicals were out. I tried the snail trap method and I just wasn’t getting the results I wanted.This nifty little tool is cheap and effective!It only grabs the snails off the glass but that’s ok because I had LOTS! Every day I would take out this tool and use it and I have noticed a significant decrease in snails. I still have plenty because they hide in my substrate and behind my rocks and on my live plants which is difficult to grab but once they make it on the walls ITS OVER!This photo is just the FIRST swipe thru my tank a little over a week ago. As you can see there are thousands of pesky snails!A few things, I wish the tool could extend longer. I have a 37 gallon tall tank so I end up having to dig my arm in the water.When you first put your tool in make sure you get the bubbles out before you try to scrape the wall, otherwise the bubbles would shake the snails off the wall before you get a chance to try to collect them.My tank has a lip at the top and some snails make it very close to the lip which the tool will not capture.other than that, this tool was what I needed!

So bear with me for story time, if you will.Somehow a single snail (one) got into one of my aquariums, I assume by hitching a ride via a snail free plant. Despite the fact I've been around aquariums my entire life, having three aquariums set up currently (35g, 75g,and 90g), ignoring that I know it only takes ONE snail to ruin everything so I Should Not Do This, I very foolishly plopped it in my 35g aquarium. Human hubris, I'll admit that. Now, depending on fish stock and tank size a very simple solution is to get a minimum of five+ Corydoras (they shoal my friends, happy cory are helpful cory) and kiss your snail problems goodbye. Seriously, the ground zero tank had that single snail for several months (I couldn't move fast enough to catch it) and thanks to the diligence of thirteen corydoras there are zero snails in that tank. No snail sightings, no sign of eggs, no moments of did the gravel move or am I losing it, nothing.Now moving on to the 35g. In a single month I that lone snail has created a massive infestation. There are eggs everywhere, snails of various sizes on absolutely everything, and A Very Upset About The Driftwood Eggs Bristlenose, it's awful. There are very few solutions to this contamination: copper (I don't feel inclined to medicate a tank of small fish in a feeble hope it kills the snails), remove the fish and boil everything (I'll never be able to catch them again in my larger tanks), snail traps (nothing suggests they actually work), or...Enter this purchase, which I like to call The Snail Squeegee.I have never bought something that is so deeply satisfying to use, to the point where I actually get a little excited when I see snails pop up on the glass. This product is very easy to use, doesn't seem to concern the fish whatsoever (my Dwarf Gourami likes to assist me by following my hand, he's offering me moral support), and seeing the snails pop off is delightful.I'm giving this five stars because I'm at a breaking point and this product very effectively makes Snails Go Away Right Now, but my only complaint is I have no idea how I'm supposed to properly get the snails out of the clear bit? Waving it around in the middle of the yard works, or a steady stream of water, so this isn't a deal breaker for me but maybe something should pop off for easy dumping? Unclear.I would also like it if the clear chamber part was a bit longer to hold more snails. After a certain point if I tilt to get one at an odd angle I have had an escapee a couple of times, but ultimately it's not a deal breaker for me.Now, that said, as therapeutic as this product is, it won't solve a longterm snail problem unless there's something to stop it at the source. Thankfully I have a team of pygmy corydoras who've been working overtime on egg consumption and I just might hire on some new recruits.Words of advice: If anyone has a snail infestation in a community tank, get yourself a very handy snail squeegee and five+ corydoras and you'll be golden. Or depending on your fish stock (ex: larger and/or aggressive cichlids who will just eat corys) just skip meals for a couple of days and they'll turn on the snails. A good gravel cleaner should also help with cleaning out eggs.TL;DR this is a fabulously satisfying product that solves part of a problem and the only thing that'd make it better is a bigger chamber for scooping up snails.

Works very well for smaller snails. The handle is only 12-inches, which means dipping your hand and arm in if you have a 30-gallon or larger tank. The materials are what you'd expect to encounter in a $1.99 child's toy. The price is outrageous, but until I find something as effective but made with more durable materials, this is the tool I will use.

It does its job. With a little pressure against the aquarium as you move up, over the little snails, it scoops them up. The handle does extend, but only to 12”. With a bigger aquarium, your hands will enter the water if you start at the bottom and go up. Otherwise, it works great.

Works great!

I can't believe I'm writing a review for a snail catcher, but this thing works so great! My 29 gallon tall tank was infested with trumpet snails, but no more. I had cut back on feeding, so they were forced to climb the walls. I used this faithfully wave after wave all weekend, and now a week later I'm still getting a few stragglers but it is a HUGE difference from before. It sounds weird, but it was so much fun to get them that I am almost a little sad I don't have as many to get! This will get the big ones all the way down to the babies! So easy to use also, I know it's not cheap, but well worth it!
