Green Water In New Tank

[r0bbbo]

Hi,

I've recently set up my coldwater tank but today noticed the water has gone green and slightly murky.

I set up the tank 2 days ago, it's 100cm x 40cm x 50cm, and only has artificial plants in at the moment. It's not in direct sunlight but gets a fair amount of light. When I filled it I used nutrafin aqua plus and nutrafin cycle. Is this all just part of the cycling process? There are no fish in it yet.

When cycling the tank should I be putting the lights on as they would be when the fish are in?

Thanks in advance for your help.

Rob

Hi there and welcome to the forum .
Sounds like an algae bloom, turn off the tank lights and cover the tank with a blanket for a few days to cut off the algaes light source and it will die off- algae blooms are not uncommon in new tank sets ups, and should stop happening once the tank becomes more established .

Nutrafin cycle is about as helpful as nothing for cycling tanks, its pretty useless and you will not be able to cycle the tank without any fish unless you put in ammonia in the tank everyday. For more info understanding how cycling works;

Your tank is;

Dimensions 100 x 40 x 50cm/39" x 16" x 20
Surface area 0.4 sqm/4.31 sq ft/ inches sq in
Volume 200 l./44 gal. (52.83 US gal.)
Probable volume 180 l./40 gal. (48 US gal.)

Which would make a good sized tank for fancy goldfish if you want a goldfish tank, however it is too small for non-fancy types of goldfish like commons and comets, which are a lot more active and generally grow a lot larger.

There are also numerous other types of coldwater fish and sub-tropical fish available if you are interested in keeping fish at these sorts of temps, although remember to always thoroughly research fish that you are interested in before you buy them, take petshop advice with a pinch of salt .
