Are the green scrub pads aquarium safe?

For the outside or areas not underwater, 3% or 6% hydrogen peroxide in a spray bottle with a micro fibre cloth. If using for the inside dry section of the tank, try spraying as little as possible to ensure you don’t overdose the tank. Some species of fish (plecos are one) are more sensitive to peroxide than others. If necessary, clean it section by section with an hour or two in between to let the peroxide you’ve sprayed, change into water. Avoid using any cleaners or other chemicals around your tank - t will inevitably get into your tank and poison the water… hydrogen peroxide will convert to oxygen and pure water when exposed to light, so is the only reasonably safe cleaner to use near a tank. To clean the glass under water, go to a hardware store and pickup a scraper blade - similar size to a razor blade, but isn’t sharp enough to cut flesh when handling! Then just use it to scrape the algae off using gentle, even pressure. You can buy holders for these to make handling them easier, but I find that most of these either have metal/rusting parts, or will hold water inside them when removing them from the water, which means you either dis-assemble them after every use, or end up with the blade itself rusting inside the holder, while dribbling rust water unexpectedly when you pick it up next time.
