    As most of the older members know, when I restarted my tank some year or 2 ago, I omitted the Closed Loop System I originally had in the tank due to visibility issues etc, etc.

    The 2 Pumps I had running the Closed Loop System was the Hailea 6550's. And as all of you know, they are electricity Consumers of note. I have, recently, Re-installed the CLS, and want to get 2 different types of pumps (technology allows me to aim for lower wattage) to run my CLS.

    I am looking for 2 x pumps, low wattage, but good, strong output, must take a 25mm inlet at least, and must be able to run outside the water.
    Any ideas based on experience and/or qualifications in this field would be appreciated.

    Also, links to suggested pumps technical info would be highly appreciated :biggrin:

    And if possible, price and store please. :)

    Can tell you this, don't know what the other will think but I fall in love with the red devil DC pumps, you can control the flow with them and they are quiet. Way smaller than the Hailea pumps

    yeah, its a tradeoff between flow and power consumption.

    What is the flow rate you want per outlet?

    How many outlets per pump? 1 or more?

    Riaan, The CLS work towards each other, same as How I had it before.
    20mm ID pipes, 8 outlets behind the rockwork (which was a mission by itself to get in).
    01 pump on either side of the ends.
    Flow basically the same as on the 6550's

    Those Hailea uses 200W and only delivers 5580L/. But with a nice head of 4m

    Reef Octopus HY-7000W Water Blaster Extreme Pumps
    7000l/h at 88W with head of 3.7M m is by far a much better option.
    But yes at about R4200 they are a lot more expensive than the Hailea that is about R1400

    you looking at basically 4 outlets per pump?
    So at 5880L/h for the Hailea, you are not really getting a lot of flow out of each point?

    I do not need a huge amount of flow as this is not my primary circulation. It is there to create movement behind the rocks as well as to prevent detritus build up (I am sure this is why my Nitrates are always high) as it is impossible to clean/siphon behind the rocks.
    Always said I wanna do away with too many pumps in the tank, but always end up with adding pumps behind the rocks for the above mentioned reason.

    you got 11000L/h split via 8 outlet ports?

    That is not a lot of flow, after head pressure due to elbows.

    Depending on what you want, is only a gentle breeze blowing from under the rocks to keep settlement out, yeah then could work.

    Else I would upgrade the flow rate drastically.

    exactly, without blowing the sand bed to the front of the glass.

    Pumps are sitting right next to tank, on the bottom, outside, meaning it is only a 1.3m head, and there are only 3 elbows on either side (03 elbows per pump). It worked 100% before with the pumps I had, more than enough flow, so only looking for something similar, but in a different wattage range, as well as with a wide outlet to fit pipe.

    I would look at nothing lower than 10000L/h per pump. Be it AC or DC pumps.

    Advantage with the DC pumps, you can set them lower via controller easily.
