Can it be put in the Fluval C3 Filter?

Yes, you can put it in the c-3 filter, but what I do is pretreat my water in a separate tank with Clearmax to remove the phosphates from our well water. For this I use a 5 gallon tank and a topfin filter, just put the bag of Clearmax where the charcoal filter goes. I use a little salt, and stress coat in the actual tank. I have never had a bad reaction, and my (adult) kids laugh about my tank full of invisible (not rare, just hard to find) fish. I am not aware of any phosphate remover that does not have an iron oxide component.If you issue is not your water source you might look to the food. I found that certain foods spiked the phosphorus levels, oddly enough, in my tank API foods that promised not to cause algae were the biggest problem.

Fluval, the back of the box states it treats 300L. Is this for each 100g pack or does it mean a total of 3 packs?

I am pretty sure it's for each 100g pack. There is no way that any filter for that size tank could hold 3, especially since the bag needs to be weighted down or it will float.

Is one pack of fluval clearmax enough for a 55 gallon tank?

kinda goes by how hi the test are and number of packets use. older tank 55 gallon i would probably use the 3 packs and test 1st day and 35th day

Would this remove the beneficial tannins from Indian Almond Leaves?

so that is a good question. I would think yes. But it really is for older setups

Great product from Fluval

I never used carbon in my aquarium. I decided to try this item from Fluval, and it actually work. The water became crystal clear more than anytime before in just a week time. The only problem I see, is that you have to replace the carbon bag each month, which is quite expensive. A Purigen bag will be an alternative, as it can last up to 6 month.
