Evergreen Pet Supplies [4 Pack] Aquarium Cleaner for Glass Walls - Aquarium Scrubber - H& Held Scraper Pad - Fish Tank Cleaning Tools Won't Scratch Glass - Aquarium Sponge for Turtle & Fish Tank

I’m amazed. The glass in my aquatic turtle tank had hard water spots that I’ve tried to clean with everything possible & safe. These sponges WORK. My glass looks new!

To my surprise, these actually work. I tried last night on a small tank with fresh algae and I wasn't really surprised that it came off easily but the size of the sponge made it a quick job. Today I tried on some more stubborn spots in other tanks and it took a couple of rounds with a little elbow grease and it worked! These are spots I couldn't get to budge with a toothbrush. I have health issues and very little energy so if it worked for me I guarantee it will work for you. My algae wasn't extensive or heavy but just some spots that made the glass less than pristine. Get these now and thank me later!

I would have given these a 5 star but they're just OK at cleaning off algae. The big benefit like other reviewers mentioned is they are much easier to hold while cleaning and you get 4. They still require a lot of elbow grease to do a decent job. The pads do hold up for awhile, I'm still on my first one.

Help a lot with cleaning my aquarium

I have never bought any other brand than API Algae pads/scrubbers; but since the price was so much less, I wanted to try this brand. I was not disappointed. I prefer a pad without a handle because I have more control and am able to apply more pressure. This pad is coarse enough to remove the stuff that collects on the glass. If you haven’t cleaned in awhile, you will have to work at it more, but this pad should do the job (if not, use a credit card to scrub the hard stuff… no scratch). I highly recommend that you give this product a try. I can say without any doubt that I will continue to buy this brand/pad. I am very glad that I gave it a shot.

It makes it so easy to clean my aquarium corners. Perfect for glass and Seiryu stones. And I like the color (red) as it is easy to differentiate it from other ones.

Great product at a great price.

Work very well on cleaning everything in the tank, but not so good cleaning the glass tank walls .

Excelente para lo que se ofrece, se lava muy fácil y es duradera

I love these sponges for cleaning the sides of my aquarium. They work amazingly well. We have hard water and a lot of evaporation, which leaves mineral lines on the sides of the aquarium. These take care of the problem easily with not much scrubbing - a couple quick passes and the glass sparkles like new.

These are the best!!! Gets rkd of crud on the tank glass without scratching it. Bought one batch and will get more. Much better than what I was getting from the aquarium store.

Great size.

I am going to use it to clean my fish aquarium walls
