Advise for filtration for 6ft tank

[bryan]

I think one of the things you need to consider is how are you going to feed your chiller.

If you use a pump that is rated suitably for your tank, it may be too powerful for your chiller.

Yet if you use a pump that is rated suitably for your chiller, it may be too weak for your tank.

The sump can be run on 2 smaller pumps, one to the main return and another via the chiller.

Have you chosen a particular chiller for your tank? For my sump setup, I am currently using a drop-in coil compressor chiller. It chill the water in the sump and you'll need only a single return pump to transfer the chilled water from the sump to the main tank.

If you need high volume water flow but consume lesser electricity, look into the Red Dragon series of water pump. Currently, I am using a 8,2m3 model that pump about 8200lt of water per hour using 75watts. There are several model available.

The above has replaced my previous setup of 2 x 1262 Eheim pump and a Resun CL650 chiller. I've managed to cut nearly in half of the electricity consumption from using 2x 1262 and the chiller cut-off time is longer at 2hr++ while it takes about 20 minute to chill from 26 degree celsius to 25 degree celsius. When it rains, the chiller will stay off longer, nearly 3hr or even more and takes about 17 minute to chill the water.

It is very important to me to find and use lesser electricity consumption equipment in order to stay in the hobby longer. It might cost more than using the standard equipment that is available but my target is lower monthly utilities cost.


Hope this helps!

Anyone knows where i can find more info regarding design and setup guide for sump tanks?

Mate, you can try to do some searching from either:
The 2 local marine forum or Arofanatics
http://www.sgreefclub.com
http://www.absolutereef.com/forums/

Search under the "Tank Showcase", you should be able to find interesting design. However do note, not all design are suitable for planted tank. Thus read it , go thru the pic to give you some idea how it was constructed and the reasons why things work that way.

No direct answer
All hard work, research, reading ...

What i thought was, it's still better for you to get a slight larger rated pump as in one with higher head. As for flow rate wise, the rated number is just a number to roughly give you an idea how fast water is "refresh".
Example: 2 time/hr more or 4~5 time/hr. Hope i don't confuse you.


Bacially,there's 2 way of running the chiller with sump system.

One method, untilising the coil system, which rolls of circular coil is place inside one of the compartment of the sump.
In this case when you size up your pump all you need to do is measured the height between the bottom of the sump to the outlet to of your tank, this should give you a rough idea the head require.

Secondly method which is the more common way. The chilling of the water is suck through one end of the sump via a return pump thru pipeline to the chiller and finally back to the tank.
Either you chiller is placed next to the sump within the tank cabinet or the chiller could be as far as an outdoor unit that you placed in your balcony. This method will require good planning on how you "run" your pipeline and also you need to properly size the return pump. Not only to ensure the return pump is able to suck filtered water from the sump but also able to "force water" thru the series of bents and elbows of the pipeline to the chiller and back to the tank.

However if you are worried that the return pump you chose might be too powerful for either the above list 2 methods, i can show you a design you can consider (if you are interested). It allows you to control the flowrate and head thru the pipeline and valves and not physically restricting the pump which cause serious damage to the return pump.

Have fun!
