To make a long story short, a few months back I adopted 6 Goldfish from a lady keeping them all in a 10G along with a Guppy and 2 Neon Tetras. There was 3 Commets and 3 Fantails I believe, may have only been 2 C. and 4 FT's but I haven't seen them in so long it's hard to remember. Anyways! One of the Fantails later passed away. < 3 RIP Black Jack. I've got the other 5 out back in a 90G because thats the only place I had to put them. (The 90G had been put outside since I no longer needed it and had no place for it indoors, guess not selling it was a good thing. Lol!) They're doing great, not growing but they were stuck in that tank for at least a year so I'm sure they'll never really grow and will sadly die young. Well one thing I've noticed is I have a HORRIBLE problem with my water turning green, like I said, I can't even remember what types I have because I can only see them if they're swimming right at the top (They're skittish so I can't watch them eat unless I'm lucky) or right at the front of the tank.

I really enjoy watching my fish, I've got a Comet and a Fantail who I bought from nnnn a year ago. (Wow I thought it'd only almost been a year but now that I think about it, it's been a year. O.O) My Comet came out of the $0.15 feeder tank because I thought he was cute. I didn't like Goldfish back then and thought they were ugly (Bad experience as a child with a HUGE Oranda who had the largest "brain" (What I thought it was at the time xD I was 5 or 6.) coming out of his head) but this little guy stood out. He was an adorable little calico colored Goldie who was only an inch long. My baby is now completely orange and about 5in, 6in with the tail. He started off in my 55G tropical community tank, then was put in with 2 other Goldfish I bought in the 90G, one died and so I moved all my tropical fish and my 2 Goldies to an 80G and then my Commet started eating my show quality Guppies and so him and my Fantail were moved to their own 55G. xD My other one was $15 and he's almost 4in I believe, 5in with the tail. He's white and orange. Anyways! Getting off topic. (I enjoy talking about them, they're my water babies. x3)

I enjoy watching them. But with green water I can't watch them because I rarely see them, I sometimes wonder if they're still all alive because I don't see them very much. :| Even with water changes it's -still- green. (90% changes since I've got so many) And within a day it's even greener! Any tips on getting rid of this? I'd like to get the backyard looking nice again so we can do some grilling parties but I don't want an ugly green tank sticking out like a sore thumb right beside where we sit. Anything I can do to help this?

Oh and for the record I've grown quite fond of Orandas and would actually love to own one, one day. Just the fact when you're 5 or 6 and see a fish the size of your head with this huge thing "coming out" of it's head that follows you when you walk by, it kind of scars you. LOL!

Before I die I want at least one of every Goldfish variety out there. x)

Hi there! I have a suggestion for you. I don't expect you'll like it but...why not keep the GW and be proud you have managed to get that . There are many fishkeepers who struggle to get green water for years. I don't know the shade of your green water but if its a nice bright deep green, chances are the water itself is reading zero for ammonia/nitrites and nitrates and your pH is stable. Have you checked recently? These are some of the priceless perks of green water systems. Professional ranchu breeders use nothing less, only green water with its capacity to keep nitrates at zero is good enough for these breeders (all the breeders here in Japan ) who believe & rightly that high nitrates cause sbd. With show ranchu, they don't take the chance and develop green water to eliminate that chance.

Thats about the color of my tank before and after changes. Give or take a little on the shade. I've seen the tank get greener than that but that was because I was gone for a while and so it wasn't changed for 2, 2 1/2 weeks. Normally I do a water change once a week though and by the end of the week the tanks around the second color. I don't have a filter on the tank because stupid me put it to far from the plug in. But they're all healthy from what I can see and doing great. They eat like little pigs and are very active. (When I do see them, they're always moving around.) I've never seen one at the top gasping for breath and the only time I've seen them laying on the bottom is at night. No clamped fins or anything to be concerned about as far as I can tell.

I haven't tested it recently. I meant to yesterday but forgot. I do free test from the pet store since I'm in there every week. I've never really had a problem with any of my tanks. (Even my saltwater when I had one) My turtle tank got a little high once but nothing where it called for serious concern just a 50% water change. *shrugs*

I'm guessing theres probably not really anything I can do anyways unless I brought it indoors which isn't going to happen as I litterally have no where to put it. (Not like mom would let me bring it inside anyways.) But I was just curious just for the fact I still live at home and it's mainly out of respect for my mom and her yard.

A true greenwater tank can have the green algae serve as a sufficiant filter for the tank. But it must be managed...... not just allowed to be green.

So much depends on what you are willing to do. If you wish to have a clear water tank, you are going to have to change the way you keep the tank. Clearwater can be run sevearl ways - the most common one we utilize here on the board is the nitrogen cycle. You must have test kits to properly accomplish this without stressing or injuring your fish. You can run a tank on zeolite - ammonia absorbing crystal - but they have to be recharged at least every week - and most likely more often. The water still will need to be changed out regularly. Finally, you can do a constant water exchange tank - where your tank is set up to have water running in and out constantly - accomplishing at leats a 100% water change at least once a week.

To get rid of the green water, you need to reduce the nitrates, reduce the lights, and up the water changes. A UV light will do the job completely and effectively, but costs a bit of money. But realize, if you remove the green water, you will have to find a different way to filter your water.

You said the tank is outside... is it in direct, full sunlight? If you want clear water, you will have to make sure it isn't exposed to such strong light, because it is feeding the algae growth.
