I purchased ciramic rings, bio balls and activated carbon.
My question is can i put activated carbon in my top filter? Because i use liquid fertilezer for my live plants. Does activated carbon good for fertilizer.
Plz help me.ignore my english
Carbon will work to remove the the non organic parts of the fertilizer as well as the organics.
This is one of the reasons I use the Seachem line of products. They have a fast absorption rate. I shut down the filters with carbon for an hour or two so the plants have time to absorb the supplements then turn the filters back on.
I do have to add supplements most days of the week. Organics one day then non organics the next.
This is the 150 tall. It has two canisters with 1-2 pounds of carbon in each. and two HOB filters with no carbon.
1,500 gallons per hour in filtration.
EDIT: I reactivate the carbon every two weeks. All of this is a pain in the neck but the plants and fish do well.
