Asolute new to the world of marine fish and need help. I acquired just a small marine tank (60litres) a week ago and could do with a whole heap of advice. Its has living rock, 2 clown fish, a damsel and a hermit (oh and a very small ugly crab) that must have made its way in on some living rock. I got it off a lady who has had the tank for 6 months, so it is still fairly new in the marine world. Anyway, first think first - algae, whats the best way to deal with it?

hello and welcome to our forum...
at first you keep your marine aquarium away from direct sunlight,then you choose a diy filtration system along with protein skimmer.then you add water mixed with declorinator ,add salt.use a saltwater mixing kit.you can use hydrometer to know how much salt is dissolved in your water.the desired level is 1.020-1.025 sp. gravity....
you will give 1 pound of sand per galon of water.then give live rock.add biological addetive to start nitrofication process.
you should install a heater to know about the temp.the temp should be 72-78frht.
then you should cycling your tank.during the cyling period you can add fish 1 or 2 per week.after complete set up you have to should well aware of water parameter and you should do water change...

Welcome to our forum. Marine aquariums are a bit more expensive and complicated than freshwater tanks, so you've taken on a challenge. With most aquariums, the keep it simple rule works pretty well. The rest, I'll leave to our marine experts.

Welcome, algae is a normal part of any healthy aquarium. Too much algae is usually due to too many nutrients in the water. There are fish that eat algae as part of their diet, but I don't think they would fit in your tank. I think there may also be some small crustaceans and snail that eat it too. You may want to do some research. Also, try doing water changes to reduce any excess nutrients. You can actually buy pre-mixed salt water for your aquarium if you are afraid to mix it yourself. I am not a marine expert, but I hope this is of some help to you.
