24 deg?! Why so low?

[neon]

Neon, do you use an external pump or canister filter to drive the chiller? It appears that my canister filter is underpower to provide enough flow rate... If not, the problem lies in my chiller

Now looking for accessories to fix up the external pump to chiller and tank. Anyone has good lobang which LFS provides a wide variety of accessories such as Hose bend, T-joint, rain bar, etc??.

Thanks

Eheim pump 1250 (1xxx+L/hr) should be good enough , or 1260 for future growth . These eheim pumps can be used for both submersible or out of tank/sump. Infact it is the same size to fit for the eheim 2250/2260/2270 carnister filter, where it sit on top of the filter. It is a good investment .

I bought a 2nd hand 2260 (with 1260 pump (2400l/hr) on top), and subsequently bought another brand new 2nd hand 1270 pump and fit perfectly on the same carnister. THe 1260 pump (3400l/hr) becomes my spare for the carnister or pump for something else

Thought it's mostly recommended by people 24 degress is the best?

[BFG]

CKM, what are you keeping in that tank? I have a shrimp tank kept at 25 deg. I always thought 25 degrees was already so low. Did you diy the external temperature probe or you get Resun tech to do it?

[CKM]

Errr... meaning not really a need to keep the water at 24 degress so that plants can grow better? (But I thought some plants need abt 24 degress ) I get the thermostat from sim lim tower. Went home try to install it myself, after blowing a few fuse i gave up and called in an electrician. now the thermostat on the chiller itself is no longer in use...

Thanks Neon, can see that you are really a fan of Eheim. Intially i thought of getting a china brand pump but was surprised that their power consumption are quite high. One model is about 400w! imagine it runs 24/7.... Saw from the website of eheim that most of their pumps are less than 100w

Just curious, it seems that you are using such powerful pump to drive the filter.. i am now tempted to connect the Ehiem 1262 pump -> 2028 filter -> chiller -> tank in order not to mess up the tank with so many pipes and hoses. Is this layout recommended? My concern is whether high flow rate will disturb the efficiency of the BB in the filter. Or should i give up the idea altogether and lets have separate chiller and hose instead.. Anyone?

[solonavi]

But how r u going to bypass the 2028 built-in pump?

zenscape: your idea of connecting Ehiem 1262 pump -> 2028 filter -> chiller -> tank is workable. you can remove the impeller of your 2028 filter and leave it unpowered. it'll remain as your biological filter.
if you worry about too high flowrate, you can throttle the outlet valve to reduce the flowrate.
that should solve your problem.

Hi Thomas, can he just dun power on the 2028? Will the filter allow water to flow through? Cos by juz removing the impeller, the pump (magnetic part( is still running?

I suggest you change the temp to 25 or 26 deg. Should run lesser. Do you still have the contact number for the electrician? I might be interested to try a Resun CL500 or CL650 but need an external temperature probe. How much does it cost you to have the probe installed?

[BFG]

Solonavi, yes he can use the method you describe. I am currently using an unpowered 2222 with a 1048 pushing the water through the 2222-> external co2 reactor->chiller->shrimp tank. previously, the 2222 was having a bit of a problem pushing water through the external co2 reactor into the chiller and then the shrimp tank. The 2222 impeller has been removed.

Spend abt $75.00 for the thermostat and $30.00 for the installation... That guy does have his own premade thermostat available but cost around $120.00... I can pass you his number if you still interested?

Thanks BFG.

The guys @ Coral Labs does repair chiller and install external thermostat. Try contacting Derek (97979910). http://www.sgreefclub.com/forum/inde...dpost&p=450376

Er.. so sorry, i am not technical inclined and pardon me.. What will happen if i just turn off the eheim filter without taking out the impeller and let the pump pushes thru' it?? Would it be that the impeller blocking the flow of water or something? Really don't feel like taking anything out for the simple reason that i don't know how to do so ...

[tawauboy]

the impeller will partially impede the water flow.
taking the impeller out is simple.
just open the filter and you'll be able to see th impeller assembly.
remove the impeller cover and pull the impeller out.

JC

when 2028 is unpowered, the impeller will partially impede water flow. water will still flow but will have to negotiate the twists and turns in the impeller.

Thanks Thomas, i will try to figure it out tonight

Hi,

Sorry , the Eheim pump should 1250,1260,1262 (not 1270 as mentioned in my earlier post) as someone had mentioned . I am actually using the 1262 pump now.

You can use the method as recommended. Bear in mind the 1262 pump easily cost around $180-250 SGD. Also, the suction/input diameter of the 1250/1260/1262 pump is using 22mm hose. I had attempted to use a reducer and clamp between the 16mm and 22mm hoses , and it was fined.

Thanks Neon. I checked the specification of my chiller and i need at least a 2500-3000 LPH pump. Thanks for highlighting the hose size..i think our standard hose is 16/22mm. I would have to run here and there again if you didn't say that.i will ask the LFS for "reducer and clamp".

Neon, i got the 1262 from C328 today, bought the 22mm hoses and clamp but LFS does not sell the reducer between 16mm and 22mm hose..Homefix also not selling. Where can get it??? anyone can help?
