Eheim canister filter (additionally) for my reef tank

[mike31154]

I use a Rena XP3 canister fitted with the XP2 top (less flow) and run carbon and GFO in it. Other than that the baskets are empty. It provides a little additional flow, but the carbon/GFO bags need to be checked periodically to keep them from accumulating mulm (NO3 hazard as per 'Aquattro' if you let it go too long). I currently don't have a sump so I count on the canister to provide a little extra volume to my system and with the nozzle fitted it breaks up the surface tension in my tank. The remaining flow is delivered by a VorTech and boy does it deliver...
