Auto water change

[Jeremy B]

I am looking at using auto water change on a 120 gallon tank, do I need to use a carbon block to filter chlorine if I use a .5gph dripper? It's run off a sump with decent flow. There are no chloramine in my water supply.

Thanks!

I would use a 5 micron sediment filter followed by the carbon block filter cartridge.  Even with no chloramine's you've got a large investment in the 120 gallon tank so it won't be a lot more to do the auto water change right and not take chances. Also the filters will keep the dripper from clogging up, which they tend to do.

Dean!! Thanks for the answer! I actually have the filters on order just wanted to make sure I wasn't overdoing it.
