The water is a greenish color.
THere many solutions firs get a UV for the water of 30W
Second not use this expensive filter selling for ponds. Many times not work fine
First get a water deposit with cover of 100 Lts
put inside matrix for filter of koi carp (you get in ebay of 2 meter square) gravel inside a sack like is use for transport fruit other time other matrix and plastic balls in other sack.
I use it and the water become clean like for drink
What happens when you bacter and other algae. YOu get a high risk of get fungus and other bad ... in your fish
for every 5000 liters add 10 kg marine sal and 1 kg in the filter
You go to see new time happy fish in few hours and in few days the green start died change the water and fill again with new water and marine sal
