I have a 4' x 2' tank which has a lot of rock in it..too much tbh and there are small areas where the gap between the rock and the glass is quite tight. I can't move the rock as there is a lot of it. What can I use to be able to clean the glass that I can't get at with my float glass cleaner. There is a line of 'muck' at the bottom of the tank just abve the surface of the sand. I have tried a small paint scraper and it won't get to all the algae/corraline. What ever you reccomend has to be really thin. I'm in the UK.
Thanks all
