Carbon

[Greenman]

I've had my aquarium running for 2 years, 29gallon with a Ehime canister filter running nothing but phos absorb and carbon. My question is how big of a difference does it make running the carbon vs running none.

Not much.
In fact, i used to run carbon 24/7 but now i'm experimenting with not running it at all for a couple weeks, then running it for several days, then not running it for a couple weeks, etc. I'm not 100% positive yet, but I think the coral does better without it.

I think the water is cleaner with carbon. Once had a a 20G full of green water. Ran carbon and in 24 hours it was clear.

I've noticed quite a difference in 48 hrs. Water went from slight cloudy to crystal clear

imo, i think its smarter to run carbon on smaller tanks such as yours.

small tanks get mucked up way too easy and carbon will help keep them clean and healthy. prob dont have to run it constant but regularly would bea good idea.

just my 2c with how its worked for me ;)

It helps to run carbon, especially in smaller tanks like mentioned, but not necessary. I personally run it all the time. It can't hurt by being in there and can only help by removing toxins.

I run carbon all the time.

Soo you think running carbon and phosphate in my canister would make a big difference in water quality?

Yep...
