Fluval U3 Aquarium Internal Filter 600L/h for tanks up to 150L

The Fluval U3 Underwater Filter provides complete and efficient 3-stage filtration, including BioMax biological filtering, to create superior aquarium water quality. The U3 Filter includes practical and versatile features, making it ideal for application in fresh, marine and reptile environments.

The filter provides the option of setting the flow output in 3 different positions, a key benchmark in underwater filtration. The adjustable 3-way flow control feature lets you position the water flow output to meet your specific needs. The Top Output setting provides maximum circulation and oxygenation, the Integrated Spray Bar setting provides a gentle, even flow for planted aquariums, and the Bottom Output setting is for deepwater agitation.

The filter also has a convenient flip-top lid that allows quick and easy access to the filter cartridge for maintenance or replacement. The filter can be installed vertically against the aquarium wall to create currents or customized flow patterns; it can be placed horizontally in shallow water tanks; or it can be used to create decorative features, such as waterfalls.

Effective but may be uncomfortable
Color: Pink & Beige, Size: Medium/Large(fits size 8 to 11)
I have eczema on my feet and use a prescription cream that I leave on overnight. I often have a problem sleeping in socks but the silicone feels cool on my feet. The only drawback I have is the opening of the socks feel very tight around my ankles making them uncomfortable on me. I wish the opening was a bit more flexible.

Burned my already sensitive feet, too big
Color: Pink & Beige, Size: Medium/Large(fits size 8 to 11)
Feels icky, and the heat gets trapped and literally felt like my feet were being burned by these. The bottoms of these feel prickly and they are way too big. You have to sit still and cannot walk in them.

Just as good as paraffin wax
Color: Pink & Beige, Size: Medium/Large(fits size 8 to 11)
I might prefer these socks over paraffin wax. They are comfy and very moisturizing. I use these socks once a week to keep the heels and soles of my feet moisturized between pedicures. I rinse with warm, soapy water then hang to dry. They are hard to walk in, but there's a saying printed in the socks that's says something to the effect of "take a break, stay off your feet" lol I love that as a reminder to put my feet up and relax

Love these!
Color: Pink & Beige, Size: Small(fits up to size 7)
Love these! As I write this review, I’m sitting in my recliner with these on. I have had other silicone socks in the past and would like to share a few of the things that I have learned. These fit great! The others were 2-3 sizes too big because you could not order a size. I wear a size 7 women’s shoe. I got the smaller size. I walked around my apartment in my old ones and they got kinda yucky. Now, I sit in my recliner, put them on and chill for a few hours. I now take them off and put in a ziplock bag so they stay nice and clean (no cat hair!). I use them once a week usually on Saturday or Sunday as I’m a working girl. Also, I use Auqaphor before I put them on and put cotton socks on after I’m finished. Your feet will be SO soft. This is not a one and done…I do this every week especially during sandal season! I know this was lengthy and I hope you got some tips.

Enables the person to move around while wearing.
These silicon socks look a bit odd at first glance but they work great and best of all, any lotions and oily creams are contained on the inside so you can walk around. They are very soft. I haven't had them long so I can't comment on durability, but they are not made of lightweight material.
