Hi everyone. I'm have a product to use in my canister filters called Cleanwater by C.R. Products. It serves the same function as carbon for absorbing wastes and byproducts and makes the water very clear. The only problem is that it doesn't say on the box what it's made of. It looks similar to carbon except that the rocks are brown and it comes inside bag pouches.

I'm wondering if anyone has used it or knows what it's made of. I don't want it messing with my water parameters too much so thought I should check here first.

Here's some of what it says on the box:
-Removes nitrite, nitrate, and phosphate
-Removes unpleasant odors
-Maintains stable pH
-Does not remove trace elements <---------

Anyone know what it is?

Well if it removed nitrates, and phosphates what are your plants going to eat? Plants need food and nitrates and phosphates are very large food groups for plants. And if it claims to maintain a stable pH then it must somehow buffer the water. I would avoid this product just like I avoid carbon. I have four running tanks and have not used carbon in well over a year.

You don't use carbon??? :shock: :shock:
How are your tanks doing? I asked a ? earlier (but no replies) about carbon. Is it necessary to remove it when adding fertilizers? My 55 gal has an emperor 400 filter. It does a great job in removing all the impurities. My nitrates level is always at zero. What do you suggest I do in order to get some nitrate to come up?

Most planted tanks run without carbon since it simply binds any nutrients the plants need to grow! This CR Product will also keep your plants from growing by binding nutrients, as Rex said.
Just remove the Carbon from your filter and your nitrate levels should rise normally from fish waste and feeding. But if you want to get them to a specific level, get some Stump Remover from the garden section at your local Wal Mart or Home Depot. Some Stump Removers have impurities in them but Grant's and Green Light both are pretty much pure Potassium Nitrate (KNO3). Check out Chuck's Planted Aquarium Pages for a guide on dosing KNO3.

Or you can get some KNO3 (which some stump removers are made from but not all) from www.litemanu.com

All of my tanks are doing fine. Charcoal will absorb nutrients and some types of charcoal will actually release phosphates.

Ok thanks guys.. that confirms my suspicions then.
Right now I'm only using coarse and fine pads in my canisters.
This should be enough shouldn't it? I was actually thinking of taking out
the fine material the speed up the water flow some and maybe adding
some ceramic pieces. What does everyone keep in their canisters?
I don't want to use peat because I don't like the coloring.

Your Filter Media configuration actually sounds good. You want that fine pad in there as well to help keep suspended particles out and the water crystal clear.

I run a fluval 204 and keep the coarse foam filter and those ceramic noodle things in mine. I also have a couple of tablespoons of crushed coral in one of the trays.

I'd like to pick up one of those fine pads to deal with those suspended particles too.
