Algae Issue In Cold Water Tank

[tgf]

I'm currently having an issue with a large amount of algae in my girlfriend's fish tank (mainly due, I believe, to lack of proper cleaning and water changing) and I am happy to clean it all up but I am curious about getting some algae eating fish in there and am thus looking for suggestions from the OCAU "fans of fishies".

Is there a coldwater aquarium fish that is simply called an Algae Eater or is there a differently named breed I could use?

Cheers,
Sam

PS: The tank currently has several large goldfish in there and the tank is about 90L in size.

Too many fish producing a lot of waste = algae I'm afraid. Are we talking common goldfish or fancy goldfish? The tank is too small for more than one of either variety to be honest with you.

Rather than adding more fish, which will only compound the problem (notwithstanding the fact that coldwater algae eaters are few and far between and often require specialised habitats), I would vastly reduce the number of fish in the tank, perform regular large water changes with dechlorinated water, make sure the tank is receiving no direct sunlight and doesn't have the internal light on for too long, and finally consider densely planting the tank with something like elodea or cabomba to use the nutrients the algae would otherwise be using.

I agree man. To many fish and to much waste. So what you need to do is

Cut down on fish

Do 50% water changes every 2 weeks to a month, adding de-cloriniator (sorry about spelling)

Maybe to to a pet shop and buy an algae scraper too. The scraper will get rid of it for a bit but yeh. You get where im going with this.

Good luck mate

an old credit card will scrape off algae or a toothbrush for the corners one goldfish needs 20g's at least to its self and another 10g's for every goldy after that do regular water changes this will help

Ive just thourght.

How often do you feed the fish? Sounds like a rather stupid question but getting the right balence of food is hard to do. And Fish shops are useless at helping people out really. But un eaten food usually is a big causer of algae. And goldfish are funny about eatting too.

Like I said, just a thourght. Not judging or second guessing you
