I so far had a mostly successfull rsm250, but I am now getting more brown algae than I have bargained for. I have had the aquarium up and running for a year so the lamps I believe will need changed. I am now a bit paranoid how much activated carbon I should be using. I thought ml=grams but I don't know if I have been putting in too much or too little. Any advice on this and if the light change doesn't work, advice on brown algae and finally I have a top up system replacing 20-25 litres of fresh non salty water every week. I do the odd 18 litre saltwater change, is this good.enough? Or should I be changing more salty water on a more regular.basis? Any help and advice will be much appreciated
