When The Green Water Is Too Green Options

[void]

Dear all green water users...

When to tell whether the green water is too green and need to be change? I've read somewhere that too much green means it contain too many protein which is bad for the lungs or something like that... is this true? thanks...

I just changed my green water tonight and notice some red streaks on 2 out of 3 of the goldfish tail fins. True enough the ammonia in the water measured 0.5mg/l.

There is only three 2 inch goldfish in the 3ft guppy tub filled with 130 liters of water. Light is MH (4200Lum) and switch on for 11 hours (7.30am - 6.30pm). Feeding is 4 times a day (only 1 click on the food timer each time) and all feeds done before 12 noon. Water changes 90% every week.

The water is usually intense green on the 6 and 7 day. Any idea why ammonia can be present despite no overloading nor overfeeding. I will be going for a overseas trip for 10 days and wonder what might happen if i dont change water for 10 days. 7 days i already see 0.5mg/l of ammonia and intense green water. Wah, 10 days really cannot imagine what might happen. Any suggestions to tackle this problem?

Anyway fish release ammonia through their gills and they also urine. yes they do just that we cannot see it.

I understand that. goldfish produce ammonia 24/7 and even till the day they died. Problem is without overfeeding or overloading the tub, the green water is still unable to effectively lower or remove the ammonia. 0.5mg/l is quite high and can be damaging to fish over the long term if PH is > 7.5

The red streaks on the goldfish tail is evident of high enough ammonia.
