Hmmm can't open the link, koko

there site is down right now

Nicely written article. I have played with a green water tub in the basement - under artificial lights. And, yes, you decidedly need a superior light source! I still had a bit of ammonia problems in my tank on occasion, but before I could solve that issue, a mouse apparently ate a hole through the liner of the tub and I had 100+gallons of green water flood my carpet and rec room. Not a happy situation. Luckily it was following a change and the fish were not yet in the tub.

Perhaps I will try again some day. Maybe during a summer when an outdoor patio tub might be possible (with raccoon and heron protection!)

I've done a small "tub pond" before outdoors. The water was completely green with one tiny fantail. After a few months, I noticed that the fantail had better coloration and looks a lot healthier. I'll try to cultivate green water again.

What am planning is to start cultivating green water outdoors, then pour the green pea soup into my tank slowly. Will this work?

Yes and No. What you are doing with green water tubs is allowing the algae in the water to process the fish's waste. You are not running cycle on the tanks - there will be no beneficial bacteria to process waste.

You can have a much lower, slower filtration on the tub, but it requires 80-100% water changes quite often - every 4-5 days was my requirement.

If you are seriously considering green water, you should do extensive reading on the subject. The article posted here is a good start.

Yeah, that's what I thought.

Another thing about black goldfishes, I recently found out from a friend that the reason why some goldies lose their black coloring is due to the lack of sunlight/algea and some sort of bad thing about dirty water.

The majority of black fish loose their black coloration because of genetics - their gene makeup dictates that that is what they will become. There is little or nothing you can do to prevent it.

You CAN, however, affect the quality, depth and/or bronzing of a black fish through various mechanical means. Sunlight and algae food, as you have stated is largely touted as being major factors in keeping a deep velvet black.

Still other goldfish people swear by pH variations and water temperature as having equally important affects on the fish's color. A black fish supposedly will remain blacker when kept in pH less than 7.0. This is dancing along the line of danger and catastrophe, though, so it is not reccommended unless you really know what you are doing.

Black is also said to remain blacker at temps under 72F. Higher temps often have been corrolated with bronzing. Since water temperature plays many important parts in the size, health and heartiness of the fish, this, too is better left to someone who has carefully researched it.

So far am trying out a small tub placed outside. I've placed a small moore in the tub and am waiting for the water to turn green. The only problem is that it's not sunny enough to make it green. But if does, I'll see how it would change my moore and will he turn black again. I'll post again in the future for the results

I have noticed that using the PowerGrow or AquaGrow light with a heater with 75-80F.The clear water will turn in green veryfast~

how many days does it take?

turn the light on for straight 3 days~n u will c thee green build up

my tank keep turning green, and i don't want that to happen
anyway to prevent it? any kind of filter media?

Sure a UV filter will kill that down for you, also make sure the tank doesnt get sun light
