Marina Large Deep Scrubber 11018

Designed with a coarse sponge which will remove most types of algaes that form in aquariums without damaging and scratching the tank. Unlike other coarse sponge cleaners which can damage the tank and seals.

Please Note: Use only on submerged or wet surfaces. The pad will scratch if the surface area dry. Rinse the pad before and after each use. Ensure no hard particles are trapped in the pad. If gravel, etc. becomes caught in the pad during use remove immediately Hard solids could scratch the surface to be cleaned. Do not apply excessive force, as this could result in glass breakage or scratch delicate surfaces
