My sump needs more filtration. My local hardware store sells carbon filter pads that are made for ponds. Will they work ok? I was thinking of cutting it to size and putting in my first baffle that goes to the return chamber. It is a 39 gallon sump on a 125 gallon tank with a mag 18 for return. I did add a skimmer but I need a bigger pump for it. The is also chateo in the center section. Pic's included.
just grab some loose carbon and place in a nylon bag, you dont need to add much more then that. since it is in a nylon bag , it makes it easy to change
Usually the carbon that is sold for ponds and freshwater tanks isn't as good for reefs, it leaches phosphates and doesn't do a good job of adding hardness to the water. I bought some cheapie carbon filter pads and they disintegrated in my sump, made a mess. I would just buy some reef carbon and put it in a bag, easy to change and keep an eye on it!
I use a sponge filter with a filter sock on top of that on my return pump that i rotate every 3 days. i tried filter media between my baffles, but it raised the water level in my sump too much.
I use black diamond loose carbon and throw it in a filter bag that's sitting in the baffles....thus far it's working great! Just make sure you have a few bags cuz they can be pretty dirty by the time you change them out.
Whichever media you decide to use, a reactor is the way to go. On my 55 gal cichlid tank, I have a Purigen pouch in a HOB filter. Maybe 20% of the media is exposed to flowing water. On my 90gal salt tank, I run 2 reactors in my sump, 1 with purigen and 1 with Phosban. Just watching every micro bead dance around the chamber shows you how much exposure the medias get. Best $30 I have ever spent.
Most carbon is good for 3-4 weeks. But a really good approach, is to take the amount you'd normally use, and split it in two! Changing one every month. That way you have one fairly new bag of carbon, and one not-so-new one in there at all times. (thanks to TDWyatt for that tip).
But I have a question...WHY do you feel you need more filration in your sump? Is it simply cause you have the room? If so, not a good reason. Skimming is the BEST filtration you can get. Anything that traps crap is bad cause that means the skimmer can't get to it.
Things like sponges, filter pads, etc are not really ideal...as it just traps excess food/poop/etc until it can break down, leaving behind gray matter, but allowing the chemically bad things like phophates/nitrates/etc to float freely back into the water column. This process really only takes a few hours...so unless you're cleaning out these things that often, it's better to let the food/poop/etc float back into the water so hopefully the skimmer can get it next time around.
Best reason for using carbon is to combat possible chemical wars going on in the tank. Using it simply to filter crap out of the water is probably not the best idea, unless you dont' have a good skimmer.

good point.......I like some people below DO think its much more effective to run carbon through a simple $30 canister filter when you do and one other indication you need to run come carbon is if you stick your nose over the tank and the water smells.....carbon will eliminate the odor as well
The reason I added carbon was to make the water crystal clear . And it worked in just 24 hours. And no I don't have a skimmer running. I will I just need to find the right pump for it. It's a red sea berlin 25-200. After I bought it I found out that there probably not so great. ANy one have a good smimmer for sale or better yet for trade.

Thank I'm going to ebay to look for it now. A Euro reef just sold for $225 I should have bought it.
