SRC Member teebs Posted March 28, 2010 SRC Member Share Posted March 28, 2010 thanks peter but where to buy a tds meter? how much roughly? Do you use the Crystal Pro unit for making DI water for salt mix or you use NSW??? The Crystal pro unit comes with a TDS meter. Alternatively, you should be able to get a TDS meter at most LFSes. I think AM has one for sale at $45.

SRC Member LaW Posted March 28, 2010 SRC Member Share Posted March 28, 2010 also really depends on the time of the day. different time on the tap water will have different readings. and yes, my tap water can hit 200ppm which is why i gave up my crystal pro after just 1 single use. one water change of about 200 litre can KO 2 resins if im not wrong. now using RO/DI. so much better interms of money saving.

You are quite correct to say that at 200ppm the Crystal Pro DI will last only ard 200L before it KOs. For my case, it lasts ard 240L before it KOs and my tap water is at 165ppm. I'm also changing to a RO/DI unit which I'm getting from US soon.

SRC Member desideria Posted March 29, 2010 SRC Member Share Posted March 29, 2010 I didn't think the Crystal Pro would be so jialat and need frequent replacements. The first round of canisters only lasted me about 3 months before I realised the water had gone up Beyond even my tap water! And after I changed the canisters, it took about 12 hours of slow drip before it went back down to zero.... Guess if this carries on of having to change so frequently, I'd be hopping on the bandwagon of RO/DI as well... Desi Quote Cheers, Desi Sheldon (TBBT): A little misunderstanding?

If your TDS was 165 ppm, you would be changing your DI catridges every month. Do take note though that once the Di resin is exhausted and you continue to run water through it, the DI resin will leach all the ions back to your water which makes is doubly bad. This is the information that I got from a supplier of RO/DI units in USA. I have already changed all the catridges of the Crystal Pro unit twice and I have finally come to the conclusion that it is really too expensive for me to continue changing catridges every 2 months. The worst thing is that the catridges are non refillable so there is no way for me to refill the DI catridges with DI resin either. I'll probably be receiving my RO/DI unit from US within the next 2 weeks and I've got in a set of replacement catridges and 1.5LB of nuclear DI resin also. The RO/DI unit I'm getting has dual water outlets, 1 for drinking and 1 for aquarium.

Agree, for big tank, need to get more efficient and cost effective models. Crystal pro probably is more is suitale for smaller tanks. (2 ft and below) I would agree that the Crystal Pro is mainly suitable for those with nano tanks, where the water volume is less than 100L. However, in the long run, regardless of small or large tanks, the running costs will still far exceed any RO/DI unit. The one I'm getting is a portable RO/DI unit with a 100GPD RO membrane. I'll probably post a review of this unit once I get it set up. Included with the RO/DI unit: 1. In-line 5 micron PP sediment - to remove dirt, sediment, rust and sand particles 2. In-line granular activated carbon post-filter - for pure tasting water 3. 100 GPD RO Membrane Housing 4. Purolite Clear DI (De-Ionized) filter - to remove hard water minerals 5. In-line granular activated carbon post-filter - for pure tasting water 6. TFC (Made in USA) 100 GPD (~ 380L per day) RO Membrane - to remove 98% to 99.99% of all chemical and harmful dissolved elements and 99% of all bacteria 7. Two-Way Switch 8. 5 feet 1/4" tube for Tap Water Incoming 9. 5 feet 1/4" tube for Pure Water Outgoing 10. Flow Restrictor 11.

SRC Member teebs Posted March 29, 2010 SRC Member Share Posted March 29, 2010 whats the cost of a RO/DI unit like? Locally it's probably around 400 and above depending on the type (3,4,5,6 stage, full size (under sink) or portable (table top)), RO membrane used (50G, 75G, 100G, 150G) and of course brand. Just take note though that RO/DI filters generate quite a bit of waste water which you will either have to drain away or keep in a bucket for flushing the toilet, mopping the floor, washing clothes, watering your plants etc. Quote My Setup: 3x2x2 tank with IOS Equipment List: Chiller: Artica 1/5HP Chiller Pump: Sicce 4000 Return Pump: OR3500 Skimmer: Deltec APF600 Wavemaker: Tunze Wavebox/2x Hydor K2/SCWD wavemaker Lights: DElighting 2x150W MH + 2x 39W T5 Atinic FR: Skimz FR Pump: Atman AT-104 Tubby ATO, Kalkweisser Reactor with magnetic stirrer.

SRC Member desideria Posted March 29, 2010 SRC Member Share Posted March 29, 2010 Hey peter, yeah i'm interested in the RO.DI unit.. I think I saw what you ordered on the marine depot website ....but I will monitor the usage of crystal pro.. if I need to change it soon again, I think I will make the switch as well and sell it off for other peeps with nano tanks rather than keep it. The costs of the catridges are almost SGD65-70 everytime I change and if I need to change every alternate month all 3 cartridges or even just the 2 resin ones (SGD50 for both), it's certainly UNWORTH It.. for the amount of water I need. Do let us know your preview on this product and if you wanna bulk order, put me on the list! Waste water.. i'd use it to mop floor and clean toilet... ;P Cheers, Desi Quote Cheers, Desi Sheldon (TBBT): A little misunderstanding? Galileo and the Pope had a little misunderstanding...
