FSA GT1-70DIALK - RO Unit

Hi all,
I recently won the FSA RO unit through one of the competitions here on our forum and have promised to do a short write up/review of the product :) However, there is a bit of a delay as I had a bad start to the year health wise so have not felt like doing anything really haha. Feeling mostly better now so here is my short review of a fantastic product! :)

Here is a link to the exact model I got from FSA:
https://www.filtersystemsaustralia.com/store/index.php/reverse-osmosis-water-filter/aquarium-systems/aquarium-alkaline-drinking-water-combo-r-o-filter-system-di-resin-1-70dialk.html

Firstly, I opted to go with the GT1-70DIALK which is the normal aquarium RO filter system but comes with an included attachment for drinking water because my family doesn't like the taste of the tap water so I figured two birds with one stone! No regrets so far. 

I'll start with the drinking water section, basically the water tastes much "fresher" than the tap water. PH comes out at 7 with a TDS of about 50 from memory (been a while since i set it up and tested, sorry), compared to 7.4ph and 80-100 TDS from the tap. I didn't do any further tests beyond this, and even those were just for fun really...

Next up, the thing you actually care about! :D The aquarium RO section! 

My water to begin with is pretty good, however I wanted to have the ability to adjust pH easily and control TDS in different tanks. i.e. ~100-150TDS in my shrimp tanks, ~50-100 TDS in Dwarf Cichlid tanks, and so on. I will be doing this using Salty Shrimp GH+ minerals for now, but I do plan to use JayC's DIY re-mineralisation mix which he has posted up for us on the forum here. TDS coming out of the RO unit is always 0, with a ph of 7-7.2, gh/kh of 0 so easy to adjust up/down, etc. Airating the drum for a few hours brings the ph down to low 6, and if i drip the water through a handful of peat in a cup I can get the ph down to 5.8 while it fills up while the TDS remains < 5 with gh/kh of 0. I use the straight RO for the shrimp, and peat filtered for apistos. Both are remineralised to desired TDS using Salty Shrimp GH+.

The FSA unit is quite easy to set up, and is literally plug and play which is fantastic as I was worried about set up especially since I live in a rental property so was not keen on messing with plumbing and so on. It comes with several attachments to connect to a tap, laundry tap, outdoor tap, etc. I keep mine in the laundry as this is where my breeding rack is. It was quite easy to set up, I had to use one of the adapters to get it to connect to my faucet in the laundry properly but this was not a problem.

NOTE: There is a small bag which comes with an o ring or two (cant remember exactly) which needs to be inserted into the adapter prior to connecting to the tap. I did not see this initially and had water leaking through the connection, easy fix and my fault entirely for rushing setup (I was keen to get it going!).

My tap in the laundry has a temp of approx 24 degrees most of the time (no hot water line in there) and I get approx 10L of good RO water per hour with a waste ratio of approx 1:1 or so last time i measured it (first 2-3 uses only). At the moment i just let the waste water run down the sink but I plan to hook it up to the washing machine or something eventually so it isn't wasting so much water. Haven't had the time/ability to work this out yet though.

It is very easy to use and overall a great quality product, it is stable on its "feet" and so on. It sits on my washing machine which would move a fair bit when on, but it hasn't budged yet haha. (knock on wood i dont jynx myself now!). The taps in the above photo are set to release aquarium water but not drinking water, you cannot have both on at the same time (i assume this would cause issues as stated in the info booklet). When the blue tap is pointing in the direction of the tubing then that is the one that will release water.

NOTE: One more thing that took me a bit of time and some questioning (and youtube watching) was getting the grey plug off... There is a small circle which you must press down with one finger (finger nail really) and then pull the plug out. It is quite easy once you know how to do it, before that was not quite easy to figure out having not used RO unit before! haha. I'll get a few photos of the process if anyone needs it! Also don't forget to let all the water run out of the tubing before putting the plug back in to prevent bacteria build up in the tubing.

I have only one recommendation for FSA which is to add a little more info on the specs, etc on the website. At the moment it seems to be fairly generalised info between the different RO units which made it hard to figure out the exact details of the model, etc. Apart from that the unit is fantastic and I would highly recommend it to anyone who wants one. They are well priced and do a great job.

Thanks for reading and I hope you find the information useful! Sorry about the lack of photos but that really shows how easy it is to set up and use! 

@NoGi - Feel free to pass on my review link to the guys over at FSA :)

      Update to say that after a few gravel vacs, front wall scrub, moss / floating plant trim, that the condition seems to have improved.  My current theory is that it is due to waste / debris management, where "stuff" like that brown mulm accumulates in the substrate and behind the HMF filters.  Maybe some tanks can somehow deal with it, but mine can't.  Also another experienced shrimper suggested that maybe those "shell bugs" don't just live on the shrimps but also in this debris.  Maybe this is the reason some tanks fail due to "old tank syndrome" where all they need is a good gravel vac? Also, I am guessing that plant trim helps too because now more of the nutrients and light go into growing algae instead of more plants? Well anyway for this tank I will try weekly water change and monthly gravel vac / plant trim.  For my next tank, I'm thinking of something like an under-gravel system where this mulm can fall down and I vac it out.

      Good to have an update and good to hear you are getting shrimplets, so hopefully your colony will continue and you may not get to the point where you have to cull some to stop over population. These type of shrimp only live 12 - 18 months so the adult deaths may be natural? If you have the time I would do weekly 25% water changes, adding the new water via a drip system and do some vacuuming clean of the substrate each week, even if only a different bit each week! See if that helps in a few months and if it does then stick with that regime? It should help reduce any build-ups that may be occuring!

      Hello again, much belated update: The tank still has "cycles" of 1-2 month "good streaks" where everybody seems to be doing well, and then a bad streak where the short antenna problem shows up again, and a shrimp dies once every few days.  I am not sure what causes things to go bad, but usually over the course of a few days I will start to see more shrimp quietly standing on the HMF filter, and so I know something is wrong.  Since I am not "doing anything" besides the regular 1-2 week water changes, I just assume that something bad is building up.  Here's a list of things that I've tried that are supposed to be "can't hurt" but didn't prevent the problem either: Dose every other day with Shrimp Fit (very small dose, and the shrimp seem to like it) Sotching Oxydator Seachem Purigen to keep the nitrates lower Keeping the pH below 5.5 with peat Things that I don't do often, so could possibly "reset" the tank back to a good streak, are gravel vac and plant trim, so maybe time to try those again. One other problem I used to have was that sometimes a shrimp would suddenly stop eating with a full or partially full digestive tract that doesn't clear out, and then the shrimp will die within a few days.  I suspected it was one of the foods in my rotation - Shrimp Nature Infection, which contains a bunch of herbal plant things.  I've had this in my food rotation for a few years now and generally didn't seem to cause problems, but I removed it from the rotation anyway.  I don't have a lot of adult Golden Bees at this point so I can't really tell if it worked or not. Overall the tank is not too bad - during the good streaks occasionally a shrimp will get berried and hatch babies with a 33-50% survival rate.  So while there are fewer adults now, there are also a bunch of babies roaming around.  I guess this tank will stagger on, but I really do need to take the time to start up a new tank.  (or figure out the problem)

      If that is the offspring, then the parents are unlikely to be PRL. I tend to agree with you. There are very few PRLs in Australia. And any that claim to be needs to show proof. PRL genes have to start as PRL. CRS that breed true after x generations doesn't turn it into a PRL. Neither can a Taiwan bee shrimp turn into a PRL despite how ever many generations. I've never seen a PRL with that sort of red colour. I have on Red Wines and Red Shadows - Taiwan bee shrimps. So somewhere down the line one of your shrimp might have been mixed with Taiwan bees and is no longer PRL. It just tanks one shrimp to mess up the genes of a whole colony.

      Sorry, missed this one somehow! The PRL look fantastic and the odd ones look part PRL and part Red wine/Red shadow in the colour. They are still very beautiful but ideally should be seperated to help keep the PRL clean if you can do that.  Nice clear photos!
