Is this a good idea?
Inlet from tank -> Ehiem 1260 -> 2026 -> 2213 -> UV -> Chiller of flowrate of 900l/h -> Outlet to tank.
Reason is, I don't want to buy another 2028 (the other two filters I already have them) and also thinking of adding a UV and I only want one outlet into the tank as of now.
Or a Ehiem 1250 will suffice?
Also, for a 3x1.5x1.5 tank, what is the minimum wattage of UV should I get to be effective?
here's my current flow
Inlet from tank -> Ehiem 1260 -> 2028 -> NA reactor -> chiller 1/5hp -> Outlet to tank.
i took out the impeller for my 2028. always OFF
flow is just nice for my 3ft tank
imo, not a good idea to get 1250. overpower is better, can always adjust flow rate with a tap if you find it too strong later
your tap must be after the 1260. using the flow control at your 2026 might cause leaking. the canister o-ring might not withstand the pressure
1/5HP? What chiller are you using may I ask?
Arctica DBA-150
How's the cooling rate and frequency of kick-in?
One of the few chillers I am looking at.
set mine at 25°C
kicks in at 25.3°C for abt 15min till 24.5°C
not sure the frequency, i suppose it's // 1-2hrs

Wow...1/5hp. I'm using 1/10hp for my standard 4 footer. Maybe few hours kick in once for about half hour to 45 mins. Didn't really monitor it.
Eheim2028 >> chiller >> tank.
Formerlly, I use a eheim1250 externally to drive it.

Why you remove the pump now?
Btw, is there a difference between putting the pump before the filters and the pump after the chiller? Will the O-rings burst?

Vincent, the actual flowrate should determine the wattage of your UVS. You can buy a bigger wattage UVS but set it on a timer to run an hour a day. UVS manufacturer has recommended flowrate. For 3ft tank I'm using 2028> 9W UVS but because you are using a more powerful filter you may need to use a 13W UVS or more.

Thanks for the info Stan. Been looking around the web to look at the recommended flow rates for the UVS.
Any recommendations of brands or things to look out for when purchasing UVS?
I was looking at the piping sizes of the Eheim 1260, and the inlet size is 25mm! Isn't that very big? So what do you guys connect this large hose to at the inlet of the tank?
If I want to use a surface skimmer at the inlet, I don't think I can fit the skimmer to the hose, can I?

Hi Vincent,
I think the 1260 is a bit overkill for a 3ft tank but then again i don't run a chiller as well.IMHO 65W is very high power consumption to run a standard 3ft tank. 2028 filter is 20W and IME sufficiently powerful enough.
My friend swears by the classic 2217. I think that would also be a good choice.
My setup is for a 3x2x2 tank[~270l], Surface skimmer, 2028, and Atman 9W UVS. Fan to cool tank but these days are hot-28.5C in day time even BEFORE the lights come on!!! [1-7pm]

1260 is too powerful for the skimmer.
i use eden501 for the skimmer.
you can connect your 2213 to the skimmer
I would agree that 65W from the pump is indeed very high. I am thus looking at alternatives to Eheim. Seems like Aquabee has lower power consumption, but the maximum head it can achieve is much lower than Eheim as a result. So it is a compromise.Hi Vincent,

And your evaporation rate will be like crazy as well. That's one reason for getting a chiller to reduce the need to top up water from the evaporation.My setup is for a 3x2x2 tank[~270l], Surface skimmer, 2028, and Atman 9W UVS.

Means alot of pipes going in and out of the tank. Trying to reduce the pipe. So for the 1260 inlet, you use just the usual filter inlet of the 2028?
Eheim1250 should be enough to drive your chiller. Now I choose to use the eheim2028 is because I want the water to ne filtered before going into the chiller, thus preventing unwated stuff to go in it, which might result in a loss in efficiency.
As in the eheim 1260, the pipings size should be the same as eheim2028. Actually, the usual grey coloured PVC pipes should fit just nice.
i use eheim installation kit for inlet as my hose is long.
using the 2028 to prime rather troublesome and ineffective for my case
I adopt the Rena method of priming. Only thing is I need to DIY the pipings all over, for the intake tube. Very easy to prime, rather than using cow's strenth to pump the eheim.
