For heavy build up of Coraline, or for even lite diatom build up, I first used to use a old plastic credit card.
BUT for better result, un-screw a house-hold electrical cover plate (the 2 hole type) and walla, a perfect rigid plastic scraper that doesn't scratch the tank, has a long side and short side to get into tight spots, and it also has 2 perfect finger holes!
I finish with a soft scrub nylon sink pad. Works great.
I have been using kent marines pro scraper with the red plastic inserts on my customers acrylic tanks. It seems to work very well and for under 10$ its a good deal. Very comfy handle on the short one. I have the long one too, but it is hard to manuver and use. JMHO. Steve
Hey Dave, I have heard that this is the new ultimate tank cleaning tool, and dosn't scratch acrylic! They say it takes off corraline like nobody's business. I havn't tried one yet, but will soon.
BTW this tool is supposed to be fully submersible, and uses AA batteries, so you could use some NIMH batteries for it to make it environmentally friendly
That thing sounds pretty good. I was going to suggest those white (usually) cheap plastic "putty knives" They are pretty hard plastic like a credit card but have a handle. There is a softer plastic version I have seen too, but I think they would be too soft (usually yellow). Just a thought
lol wrightme....I've tried to use him before but he leaves a lot of pits in the tank wall....besides i caught him stealing peanuts from my cupboard.....
I use a mag float with a piece of blue filter stuff on the inside float. If you do pick up a grain of sand it sinks into the filter and never touches the acrylic.
Tom, that thing would make a good skimmer cleaner, I've been using a toilet brush.
i've tried this battery powered brush thing and it doesn't do much for me. it really won't remove coralline algae like the RC threads indicate. After trying mine I wondered if some of the folks at RC even know what coralline algae is.
I use Kent srapers for algae but I have scratched acrylic using them.
I was in a Black&Decker outlet store last weekend and they had a fully submersible scrubber shaped more like a drill. It had several different functional heads including a car buffer which I was going to use to polish out the scratches on the inside of the tank.
