Hi there. I'm new to ReefBase but have a question. I've had my tank for about 7 years its 180l marine tank with a sump underneath. Over time sand has accumulated in the sump. For a while I couldn't work out how it got there but then I realised that when I used the scraper 2 clean the side of the tank It disturbed the sand which then in a very fine form has accumulated in the sump (about 20% of the sump is full of sand). The sump is full of cheetah algae at the moment. Should I remove this sand and put it back in the tank or leave it and add new sand to the tank.

Hi, welcome to ReefBase  8D

Personally I'd remove it from the sump and put it back in the tank because I'm a too tight to buy new sand when I've got some already sitting there in the sump!
Unless of course you wanted to gradually switch over to sand with a larger grain to stop it happening.

As long as you do either option in small sections at a time there should be no problems with the chemistry of the tank, nitrogen cycle etc.
