Hi, me need to borrow UV filter for my 3ft tank,
for the pass few days i have being fighting against green water,
i did the water changing everyday(20%) and even do the Black-Out mehtod for 3day.The water only improved a bit, but my poor Riccia turn brown.
but the water still a bit cloudy. That is why i really need some helping hand ,i will be very happy if anyone of you who has a spare/standby UV filter can lend me to get rid of the GW.

Thanks
