Exactly what I did to mine.If it's bacteria bloom then adding a UV steralizer can help it to stay cleared up.
I sometimes experience a bacteria bloom when I do a large water change. It used to take a day or two to fully clear up but I recently added a SunSun canister filter that has a built in UV steralizer and if I have a bacteria bloom now it is usually cleared up in an hour or two. I can't say for sure that the UV is the difference but it seems coincidental that this started happening when I added it so I am willing to go ahead and say it works.
I have similar problem last few weeks. I've been keeping fish over 15years i've never ran into cloudy fish tank before. until last month. I have 4 FX6 running and i never ever have any problem, until I cleaned 2 of my FX6 . Even when I cleaned with the water from the tank, with this I encounter bacteria bloom. I notice right away after a couple of days when my tank never clear up.
- Adding new or more filters wont help
- doing water change, 30,50,80% wont help
- shutting light off all day wont help.
- adding all kind of softner or any kind of chemical to clear up the water wont help.
My tank been running cloudy for a month until I gave up. I finally order UV ster 36 watt turbo twist. I installed it, next day it clear up 50%, by the end of the week it clear up 80%. Then I did 30% water cha
