Here some problem I have using oil dry from safe t.
After a whole week of washing and remove the small grim and using the bigger size.
The last wash look clear so I end up pulling it in my tank.
After 2 week in the tank with 90% water change every 2 days I still get brown water.
My 2 filter pick up most of it. Pic below show you how dirty it is after 4 week of washing and filtering it.
The red thingy is what I use to remove the small size from the big size.
