[ah^siao]

any bros here using for their own use, for their fish tanks, or planning to buy 1 to use it for their fish tanks?

Better to use RO/DI right?

[ah^siao]

y is it better to use ro unit? from wad i know ro water got totally no minerals and no nothng in it... minerals are important to living things...

You will get all the minerals u want from the salt we add in There are more of harmful materials in our tap water source than the minerals we want.

Rav: I know that a RO unit produce quite a lot of waste water to obtain the RO water required. Eg. To obtain 10l of RO water, 45l of water is wasted. What about a RO/DI unit? Any water wastage?? Heard that the wastage will go thru the DI and be used... wonder how true.

[Ekia]

Just went to search the net for more info... seems like DI is run directly after the RO process... which means there will still be water wastage. Not like what I have heard.

[weileong]

A booster pump to ensure that the pressure going into the RO stage is high will reduce the waste water ratio.

ok another question... y is it that the fishes in the sea seems to be livelier and healtier than the fishes in our tank?

is it cauz we lack of something in the water itself?

if u don understand the question i stated above.. think of it int his manner.. a computer nerd who stays at home everyday playing the computer and study is no where as healthy as a beach hunk or a person who does outdoor sports.. Y is it so..

the above 2 situation is very similar as the fishes in the sea is like the person who does the sports and fishes in our tank is like the computer nerd who stays at home..

Ekia, the so-called waste water is actually clean water, safe for drinking and even to water plants. wash clothes etc etc... Juz not good enough for your precious reef which requires pristine water quality!!

yah I know.... but u have to find some way to make use of it... need to have large storage containers. Not suitable for ppl like me staying at HDB flats.

Yeah, I understand... see if you could use those coralife salt buckets??

Or maybe attach the waste water tubes directly to your washing machine??

Or your doggie bowl?!

[ah^siao]

ok if u say pristine water quality.. does diamond water fulfill the conditions?

[AquaRa]

wad does diamond do.

[ah^siao]

diamond water simply remove all the minerials and all the chemicals in the water system.. so it's as good as a RO unit...

if there is a another system that is able to remove all the chemicals but not the minerals, is it better???

[AlfaRomeo]

Bro, we should be aiming to use pure water as top-up minus all chemicals and minerals and contaminants. Same goes for water being used to with the salt-mix. All the necessary elements/minerals will be provided for by the salt-mix

So far, its best to use RO/DI for top-ups and water-changes. Those distilled water in 5G containers can be used for Water-changes too.

[ah^siao]

isn't the extra minerals can be used by the fishes also?

[AlfaRomeo]

I dunt think the fishes use minerals from the water. They get the vitamins/minerals from the food they eat?

Minerals from top-up water could be used as fuel for algae in the tank tho. So i think its safer if we get as close to pure water as possible.

[Gouldian]

Hi Alfa how about if we just used DI unit? It is cheaper and it does not have wastage????

[AlfaRomeo]

Bro, the cost of replacing the DI Resin is more expensive than the waste water generated by a RO. The RO part will clean the water significantly and thus the DI will last much much longer Also, I think with DI only, u cannot get 0-1 TDS..

[Ekia]

Anyone tried the 6 stage RO/DI selling at ebay? RO/DI

I think the price is very affordable but not the shipment. In fact, the shipment actually cost more than then filter! Think I have seen this discussion months ago and someone actually shipped one over... wonder how's the performance... Next time should ask someone to hand carry over

[AlfaRomeo]

Problem with the 6stage is the cannisters. We should be looking at transparent cannisters instead of opaque. Transparent cannister will be good to see at a glance if the DIs are exhausted or the filters clogged.

If I'm not wrong... the transparent canister on top is holding the DI resin... should take care of what u r worried about

What about the rest of the cannisters? Any Idea how to chekc the condition of the prefilters etc etc?

[hamannbmw]

reefer guy is using one of these.. i'm also thinking of getting one for myself

[ah^siao]

hmmm..how much does one of these units costs? and how much it cost to change the filters?
