Sump Plumbing Through Chiller

[thefirethief]

I'm planning my first sump for a 24gal tank and the plan is naturally, to make loads of mistakes. Just wanting to make sure I'm not gonna make any that can't be changed later so I'd like to hear if there is anything glaringly wrong with what I've come up with so far.

Its a 24Gal tank connected to a to 10 Gal (approx) sump.

I'm going to get it drilled in the next few days so my biggest concern just is the size of the bulkhead I'm going to need. The chiller recquires a flow of at least 250lph and max of 1200lph which leaves me quite a lot of room for maneuver.

Obviously flowrate will be reduced by the chiller, by how much I dont know. It'll be a mud sump so a high flow rate isn't needed. Would a 20mm bulkhead be compatible with something like the eheim 1048 which runs at 600lph?

I've been doing some more reading and I think I may be able to answer my own questions.

A 20mm might work, but a 25mm would probably be safer...

I would NOT reccomend a chiller. A window mount air conditioner will use just as much electricity, cost less, last longer, and keep both you AND your fish cool.

Thanks skifletch. Am I right in saying that as long as the return pump has a lower flowrate than the overflow and everything is setup correctly then I shouldnt experience any problems with the sump draining?

I've actually already bought the chiller. Its for Hippocampus Breviceps which require a temperature low 70s/high 60's. Despite living in Scotland the odd sunny day plus the fact the room also contains two tropical tanks means that the ambient room temperature is often a fair bit above that. The chiller should give me more control over the actual water temp rather than the room temp. It will be peace of mind at least.

Oh, a cold water tank . Yes, you can certainly run the chiller off the return line
