FSA GT1-70DIALK Portable R/O Combo System

Recommended Posts




Before making your decision to buy an aquarium filter look beyond the price and consider the following. Yes there are cheaper systems on the market to produce DI quality water for your aquarium.
However when you look closely at these systems you will note the following.

1/ The systems consist of small DI canisters which hold very little DI resin. Di resin expires fairly quickly particularly on high TDS water like Perth, Adelaide and Brisbane. The higher the TDS the higher the residual percentage of TDS left by the RO. The purpose of the DI filter is to polish the water to pick up any residual TDS (salts) left after the RO membrane. The higher the residual, the harder the DI works, and quicker it expires.

Our system holds 350gm of nuclear grade Purolite Resin - the best in the world. Most other systems are offering less than 200 grams.

2/ Its pointless spending over $100 on a water filter for your fish if you can't take advantage of the your investment, and drink the water as well. We are constantly asked for an RO System that is suitable for drinking and aquarium water. This hasn't been possible until now.

DI resin removes the mineral content back to Zero which is great for the fish but not so good for your health. When the DI removes the residual mineral which include natural pH buffers, the pH of the water plummets to below acceptable levels for drinking water.

For example the pH after RO and DI can be as low 6 pH or even lower pending temperature etc. Basically this water is acidic and not suitable for prolonged use as drinking water. There has been a lot said about drinking acid water some of which you can read on our listing for the 6 stage XstreaMn Shuttle RO system or our 7 stage XstreaMn system.

We have built this system to accommodate both needs; safe drinking water and or DI (mineral free) water for aquarium use.

We use the highest quality components including Purolite DI nuclear grade resin, and the new and exclusive GT6- 18LS pH neutralizing cartridge for safe drinking water.

      Hi I signed up awhile back but this is my first post so I hope I'm in the right section. I've been keeping crs/cbs for a couple of years now, starting with a dozen and now have approx 200. I have a large 200lt tank and use fluval stratum. My parameters have always been pretty steady, tds 130-150,  ph 6.7-6.8, GH 3-4 and KH 1-2 and have had great sucess but over the last few months my KH is reading zero and the PH has gone from 6.8 to 5.9!! All shrimp are still doing well and no noticeable deaths but the ph drop is concerning. Is this directly related to zero KH? (No buffering) Any advice on the cause and any action that I should take would be very much appreciated. Thank you

      I have had a 20 gallon RCS tank for 3 years now.  I have moss balls and some JAVA moss, drift wood, and mineral rocks.
      Only RCS in the tank and some soft shell snails I have in there I breed for my fresh water puffer fish in another tank,.
      My issue is that the shrimp live 1-2 years and they breed just fine but I never see babies.  I see plenty of eggs but never babies.  (Well 1 or 2 a month maybe but they disappear)
      The adults keep going just fine until they die off of old age or something else.
      I keep about 100 shrimp in the tank and have to replenish 50 every 6 months about.
      Water Temp I keep about neutral. 
      PH- 7- 7.2
      I use distilled water or sometimes Reverse Osmosis water because our tap water goes through a water softener which puts a LOT of salt in it which makes TDS very high so I try not to use tap water at all.   
      I feed every 2 days with Azoo or other good food and not much.  Its all gone by the time I feed again.
      I do add some powder food for the babies and a shrimp bacteria powder (just started that about 6 months ago but has not helped or hurt)
      Someone told me due to the distilled water my issue is LOW TDS.  So I bought TWO different meters.  I tested the distilled water and its about zero which is correct.  I then tested my water and its about 700.   I do top offs and just did a 20% water change last weekend with distilled water.
      So is that the issue?  Should I pull out the mineral rocks?
      I am thinking tonight to take about 8 gallons of water and drain the tank down about 40% and then fill with the distilled water.   I can repeat the process in a week and once I get the TDS under 150 I can add a little shrimp mineral to get it to the 200 range.   The reason I am saying that is the TDS could be bad TDS and not the minerals they needs.  I ordered some Salty Shrimp Mineral which I heard was good.
      Should I just give up?

      Another mother-bleeping dead adult. I have no idea what’s going on. You’d think all these micro sized babies would be dying too.... I don’t get it.
    • sdlTBfanUK
      This really isn't going well this time. I am not really sure why either? The plants are nowhere as green and lush as the other tanks and the shrimps seem to be dying off slowly despite all parameters being perfect! The different substrate must be part of this but as it is shrimpking I can't believe it can be the main problem! After a lot of considering the only thing I can come up with is I tend to do this tank the same day as I do washing so I 'MAY' be contaminating the water if I have some washing product residue on my hands but this is really clutching at straws - it is the only thing I can come up with and a possibility............... I have left a note next to the tank to remind me for the future! I am thinking of changing 50% of the water and 1 of the 2 sponges at the weekend and running the tank for a few weeks then trying One last time a new batch of taiwan bee shrimps, and at least they will be in situ by the end of our winter so they should readily breed this lot? I probably have just under 10 shrimps left. Any advice appreciated on what they would do? I have a few days to mull it all over? Simon

      Two weeks ago on the fert.   no, it’s only on the upper side along the back, and some along the sides. I want to upload  better pictures but this is confusing. It won’t let me.... the threshold for file size is never the same...
    • sdlTBfanUK
      When did you last use the ferts? If you are doing that once a month and that was within the last week it may be that? It could be the eggs in the saddle if the shell is a bit transparent, does it just appear in that area? Simon

      I will try, this phone doesn’t do great pictures.   I started using on squirt a month, just for the iron. The red plead plants were suffering. Heater is operating normally, and I don’t THINK I did anything to the tank to cause introduction of something to kill them. I suppose I’m being too picky as it was clearly two of the older,  originally purchased adult shrimp.    The marking wasn’t originally there. It seems to be on females, and only when they are berried. It then never goes away.
