Well, I've killed a lot of fish from lack of knowledge/bad advice.
Any container that has water in it will get slimy over 48 hours if any bacteria is present. Plastic/glass/metal/concrete.
The trick to getting the right answer in a forum is asking the right question & phrasing it so everyone can understand what your concern is.
The problem at the petstores, everyone assumes the people who work there are experts, but when you ask, What kind of fish do you have? & they reply, "I don't keep fish", it makes it a lot harder to take their advice seriously.
Any product that I recommend is something I of some of my friends have personally used & had good results with.
Like most things, you get what you pay for, but I like to support the companies that produce quality products.
It's amazing when you come across something aquarium related that was made in the 70's or 80's that still works today.
Save your paper towels & get that fusion acrylic pad. Before I responded to your post, I didn't EVEN know the name of the scrubber I was using & where to buy another one.
Fusion makes one for glass tanks too, but stick with the pad that's designed for acrylic enclosures.
Some tips when using the scrubbing pad....
- Use small circular motions like in the Karate kid.
- Apply light pressure
- Algae spots will require more pressure to remove.
- Go slow around the silicone sealed edges.
- Be careful around the silicone seals.
- Be careful when you're getting close to the substrate, don't get any gravel/grit dirt stuck in the pad.
- Rinse the pad continuously in the tank while you're cleaning.
Once you're done cleaning with the pad...
- Rinse it out with cold water
- Let it air dry until you need it again.
Don't microwave it to sanitize. It's not a kitchen sponge. Air drying is good enough.
Any particles that get dispersed in the water during the cleaning, will be removed with a decent filtration system.
This is another reason to have a standard filter in your tank if you like the water to be crystal clear.
Another note.. I don't remove my fishies when I use the pad. They like to watch and snack on the algae during the cleaning.
