no need pump...fix your pipe directly to it..the red part is the tape to prevent leakage...the cartridge is the whole pvc hosing...when u change...sam will pass u another DI unit...as in a new PVC hosing and thats all...

u dun need a pump... just run all your tap water that u need to top-up or change thru this pve pipe and collect the de-ionised water

Just return the pipe to sealife and he will replace a new one for u.... which means he either has one standby in the store or u return the next day to collect it...

That's cool.

Are there any indications to alert you that it needs to replace?

If not, how do you know.

estimate lor...around 1000L

Agar agar not so good unless you test the water using a TDS water quality meter ...

So this things works?

I used for a yr, so far so good. I change a pail of water bi-weekly and cart lasted for almost 1/2 yr before it get exhausted. The setback is the water flow fm tap to DI need to be slow/low pressure....always forgotten to switch off the tap.
