closed loop

[plugpitch]

anyone experienced with a closed loop run into problems with their lines being congested by debris? I am considering using a closed loop that goes through my chiller

if your intake is managed properly, such as lots of small holes, you should be fine. ive not seen one plumbed thruogh a chiller, IMO not a good idea. ive been accused of being harsh in the past, present & probably the future. my opinion, is not that of RC, or its affiliates. REEF-ON!!!

Hrm...not really experienced in that, but for some reason doesn't sound like such a great idea.

i HAVE MINE SET UP THAT WAY FOR 2 YEARS AND NO PROBLEMS YET

Typically, a closed loop is HI flow, which is more flow than the chiller can handle. If this is the case, you are loosing cooling power (efficiency) of the chiller. Other than that, I don't see a problem.

If you have screens on the intake bulkheads, all the tiny particles just get pushed through by the pump and keeps the snails and fish out. The flow is so high, anything that does get in (usually something waste particles like when my shrimp molts) always seems to get shredded and returned to the main display. Make sure you use unions and valves so you don't have to drain the tank to do maintenance on the pumps.

Oops, sorry - didn't have my coffee and still not fully awake.
RE: plumbing through chiller - I thought about that too but decided against it b/c I figured if anything did get stuck inside the chiller, it might be a nightmare to get out. I just left my closed loop as is and Plumbed the chiller through the main return pump - I had to upgrade to a stronger pump though. The return water area of my sump is much cleaner so I'm not worried about debris in there.

i am not trying to have a high flow closed loop. I was trying to get away from having one more thing in my sump. Also, I figured that I could add a little more flow to the tank without worrying about a power outage. Still a good idea as long as I have an intake strainer?

My only conern with closed loop is a probably high loss of flow, if you aren't worried about losing flow, then go for it. Just use ball valves and unions.
