I found a local person but I don't think his units have the GAC, assuming I should get one with that. He emailed me this info below.

Here's what you'll get, first of all my unit are custom built one at a time, installations free.

stage one: 1 Um sediment filter - upgradeable to a .5 Um ceramic sediment filter (add S$20)
stage two: Kemflo~T33 OCB GAC coconut carbon filter
stage three: the work horse (matrix CTO Carbon Block ~ KX) the best filter on the market
stage four: you can either have a 100 or a 75GPD membrane - Dow Filmtec (100GPD has a rejection rate of 90%* 75GPD has a rejection rate of 99.6%)
stage five: nuclear grade mixed DI resin

yes it looks like a very good unit. both the 2nd and 3rd stage are GAC. The coconut type carbon filter i heard is the best. the dow filmtec membrane is also the standard and considered the best. the first is a sediment filter. do you know if you will be able to see inside the cartridge on the di side? kinda important because the di resin changes colors when exhausted and that indicates it needs changing. since there are two types of di resin you also want the mixed version to take out both the positively and negatively charged impurities. the two type of di resins are anion and cation types. so get both mixed in a cartridge to get H2O and nothing else! thats chemist grade water, pure, unpolluted "dead" water.

this is what i mean by clear cartridge. the canister is viewable so you can see the resin and the filter cartridge is clear. when the resin turns from greenish/blue to yellow it's time to change the resin!

which skimmer did you get? can i assume you are surface skimming? btw i use 2 di cartridges that way i can rotate which comes first after initally installing the filter. as the first chamber in line is used up i change the di resin and swap the second to now become first and the newest di cartridge is always second. this saves $ in the long run because the di resin can get expensive and this allows to exhaust 100% of the resin in the first chamber always!

Its a small surface skimmer that attached onto my external pumps outlet. Inside the fish tank where the water is drawn out it attached to that. I mean it doesnt do a whole lot of water per hour, but its doing the job! Top of water is already clean. I mean once i add fish this might change but something is better than nothing.


Good suggestion on the RO/DI I'll make sure I ask those questions when he comes over saturday!

naw, the surface skimmer works 100% of the time! even if it's a small amount of water continuously overflowing into it. one other thing that can happen is that if the surface is not agitated then the water can become caught in a area where it countiuously rotate in the area and never gets to the skimming cup. if this happens you'll see the slime on a portion of the surface that never gets to the cup. what you do there is put power heads at the surface to create a current that mixes the surface continuously and direct the flow to the collection cup.
