juggernaut Posted January 10, 2010 Report Share Posted January 10, 2010 Has anyone had green water in their tank before. I can't correct it and it is very frustrating as i can't see my beautiful little fish. Water changes help it temporarily but after a couple of days it goes back to being a thicker green colour. Carbon is being used and i change it every time i do a water change so it doesn't expel and of the impurities it may have absorbed. Ammonia is non-existing and pH is at neutral. There has been little spots of green algae at times on the glass of the tank but nothing out of the ordinary. little bits of beard/ hair -like algae on the hairgrass but that doesn't seem like it could cause the water to go green as much as it is. The daily amount of light on the tank is 10 hours and the tank is positioned in a shady spot but can get a little sunlight on it at times and perhaps could be in a better position if required. Please help with any logical suggestions because my logical solutions have been exhausted!!!! Quote Link to comment Share on other sites More sharing options...
N1CK Posted January 10, 2010 Report Share Posted January 10, 2010 welcome to the forums Regarding your problem, most algae is caused by an imbalance of light and nutrients. I doubt the carbon is helping the problem also how much light is your tank getting? (sunlight included) lowering this could help quite a bit Quote Link to comment Share on other sites More sharing options...
Caryl Posted January 10, 2010 Report Share Posted January 10, 2010 Hi and welcome. I too wonder how much sunlight your aquarium is getting as you mention small dots on the glass. Where are you? (It would help if you added your location to your profile - click on the User Control Panel at the top right of the page and find where to add it there). Where does your water suply come from? Mine is artesian and I find algae can be a problem over the summer months when the water table is lower. I suspect a higher concentration of nutrients for the algae to consume. What size is the tank, how long has it been running and what species, and how many, fish do you have? What is the pH? Have you tried cutting back on the feeding? What sort of lights do you have and have you changed one of the tubes/bulbs lately? Quote Link to comment Share on other sites More sharing options...
livingart Posted January 10, 2010 Report Share Posted January 10, 2010 i have just had a problem with 3,000 litres of green water in direct sun did frequent water changes, added lots of plants, cut down light and ensured any uneaten food was removed quickly problem has been solved Quote Link to comment Share on other sites More sharing options...
spoon Posted January 10, 2010 Report Share Posted January 10, 2010 phospates can also cause algae problems could just be in your water naturally but id try the advice about light first Quote Link to comment Share on other sites More sharing options...
stillnzcookie Posted January 10, 2010 Report Share Posted January 10, 2010 We solved this in our 60l tank by doing a big water change, then blacking out the tank for 3 days, then doing another big water change. We discovered that it was caused by early morning sun shining on the tank, so we now put a towel over the tank every night, and only remove it when the sun is no longer hitting the tank in the morning, and we've had no more problems.

breakaway Posted January 11, 2010 Report Share Posted January 11, 2010 Another alternative would be to install a UV Filter. Quote Link to comment Share on other sites More sharing options...
N1CK Posted January 11, 2010 Report Share Posted January 11, 2010 Another alternative would be to install a UV Filter. those are rather expensive, and they don't actually fix the problem itself. Only kill off the algae which makes the filter then clean out all the gunk Quote Link to comment Share on other sites More sharing options...
Ira Posted January 12, 2010 Report Share Posted January 12, 2010 I found rubber banding some filter wool around the filter intake and then rinsing it out when it clogged up(every 3-4 hours) cleaned up a tank that you could only see 2-3" into in about a day or so.

juggernaut Posted January 13, 2010 Author Report Share Posted January 13, 2010 Yea pretty new to all of this so take it easy on me!! Ha. Awesome replies i've been reading these forums for a while now and i thought someone would have some possible solutions. Water in the house tank has just been bought and im unsure where this is fetched from but water was going green just before this so i has to be something to do with the light. My aquariums water capacity is 200L and it contains a pleco, about 6 platys, 2 golden algae eaters (they munched back the brown algae problem i had a few months back), 2 X-ray tetras, 6 cardinal tetras, 2 loaches (forgot what type!!!) and 2 other tetras (forgot what type those are also!!!!!). Relocated from Rotorua and tank has been cycling for about 3 months in its new spot. Quote Link to comment Share on other sites More sharing options...
