I picked up a secondhand ro unit early this week, but I don't know anything about them. I know it needs a part to connect the hose to the tap and I should probably replace the membrane as well, but I don't know where to get parts from. It did come with 4 new filters. The unit is about 3 years old and hasn't been used for about 12 months. The storage container is still filled with water, but I'm guessing that water wouldn't be safe to use? Here's a pic of the unit.

I figured $50 for the unit & filters was an ok price as long as it works. Although hubby isn't impressed with the 7x2 ft tanks (I cracked 1 unloading it though), some corner filters, sponge filters, breeder nets, gravel and some other odds and ends that it came with.

$50 for the lot or just the RO unit?

Bargain if it was the latter.

 

Still a bargain for just the RO unit.

 

Dump the water that is already in the container. 

 

I can't quite see it in the picture, but looks like you will need the 1/4inch tube to faucet adaptor.

Best to talk to FSA to determine what faucet adaptor you need.

 

After getting that adaptor, hook it up and get some RO water  from it to determine if you need to change filters by testing the TDS.

The filter might still be ok. I usually change filters when TDS is above 10ppm. Could probably change earlier, but I'm trying to save on filter costs. So I make it run longer by changing only when TDS is above 10.

Thanks Jayc, l'll give them a call. It was $50 for everything and it came with 2 types of cartridge filter and 2 sediment filters that are still sealed in plastic.

Just have to convince the other half to let me keep the tanks and build a rack as well lol

Spoke to FSA and they were extremely helpful. We have a new tap adapter and membrane being sent out next week and I know how to set it all up now. :-)

Working on the other half to let me start up the other tanks, but that could take a while.

And my TDS pen is one of my favorite gadgets :-)

The new membrane and tap fitting has arrived, so time to start setting it all up.

The kids and I will be away for most of the holidays, so I need to make sure everything's done and there's extra water made up for the OH to top up the tanks while I'm gone.

Just finished replacing the membrane and filters, and connecting all the hoses and fittings. Turned the tap on and water is gushing out of the filter compartments but they won't go on any tighter. Of course my torch goes flat before I can undo them to see if I've missed something or something's moved. I asked my OH if he thought I should undo them and use Teflon tape on the thread, but he says it's a bad idea and it could be the o-rings if they have any. I'll just have to wait for the torch to recharge enough or tomorrow to check it out.

Yippee! RO unit is up and running. All the leaks stopped leaking without being touched, flushed it for over an hour, repressurized the storage container and now it's full and my 20 litre bucket is full. About 60+ RCS are being drip accliamatized to the refurbished 80cm fish tank. 5 very pale male RCS are being drip accliamatized with RO water to make sure all the presservative has flushed through the RO, some Benibachi soil has been siphoned out of the CRS tank as it's buffering to low and their tank is slowly refilling to. Still 100+ RCS to take out of the Mischling tank & 5cm more Benibachi soil to come out of the CRS tank, but that will have to wait till I get back. Hope hubby has no problem with our shrimp while the kids and I are away

      Shrimp molting before eggs are hatched

      By sdlTBfanUK · Posted

      I would hazard a guess that perhaps those eggs were unfertilized and thereby unviable? Did the eggs change colour, usually yellow to grey as the yolks used up, or any eyes in the eggs. Is your water ok, using RO remineralised and the parameters in range, as I have heard others say that if the water isn't good it can 'force' a molt? How is it going overall, do you have a good size colony in the tank, you may have reached 'maximum occupancy' as a tank can only support so many occupants.

      Shrimp molting before eggs are hatched

      By beanbag · Posted

      Hello folks,  The current problem I am having is that my Taiwan bee shrimp are molting before all their eggs have hatched.  Often the shrimp keep the eggs for 40+ days.  During that time, they lose about half or so, either due to dropping or duds or whatever.  Shortly before molting they look to have about a dozen left, and then they molt with about half a dozen eggs still on the shell.  Then the other shirmp will come and eat the shell.  These last few times, I have been getting around 0-3 surviving babies per batch.  I figure I can make the eggs hatch faster by raising the water temperature more (currently around 68F, which is already a few degrees higher than I used to keep it) or make the shrimp grow slower by feeding them less (protein).  Currently I feed Shrimp King complete every other day, and also a small dab of Shrimp Fit alternating days.  Maybe I can start alternating with more vegetable food like mulberry?  or just decrease the amount of food?

      Shrimp and meds containing gentian violet

      By ngoomie · Posted

      Yeah, cancer risk was a thing I'd seen mentioned a lot when looking into gentian violet briefly. I kinda just figured it might only be as bad as the cancer risk of malachite green as well, but maybe I should look into it more. I've been doing a pretty good job of not getting it on my skin and also avoiding dunking my unprotected hands into the tank water while treating my fish at least, though. Maybe I'll just not use it once I'm done this course of medication anyways, because I know a store I can sometimes get to that's pretty distant carries both malachite green and methylene blue, and in pretty large quantities.

      Shrimp and meds containing gentian violet

      Can't help you with Gentian Violet, sorry. It is banned in Australia violet for potential toxicity, and even possible cancer risks. I thought it was banned in Canada as well. At least, you now know why there isn't much info on gentian violet medication and it's use. But keep an eye on the snails after a week. If it affects the snails, it might not kill them immediately. So keep checking for up to a week. Much safer options out there. No point risking your own life over unsafe products.

      Shrimp and meds containing gentian violet

      By ngoomie · Posted

      Hello! I have a tank that currently does not contain shrimp, but does contain neon tetras which I am currently treating for Ich, as well as some bladder snails. Shrimp will be a later addition, likely cherry shrimp but I'm still doing research just to be sure. Initially I'd intended to buy some sort of Ich-fighting product that contains malachite green after doing a decent bit of research on it, most of which indicated that it should be shrimp-safe so I'd be good if I ever needed to use it again once shrimp were actually introduced (though I should note I'm aware shrimp can't get Ich, I'm more wondering in case the tetras could get Ich again, or something else that responds to similar medication). I ended up not being able to find any MG-containing products without either having to travel quite far or wait multiple days for delivery (which I was worried could lead the Ich to be fatal), and ended up picking up 'Top Fin Ick Remedy', a product that contains gentian violet which is a triarylmethane dye like malachite green. The bottle has two slightly differently worded warnings about its use with invertebrates ("not recommended for" and "not safe for" respectively), but when I'd been researching malachite green, I'd also heard of products that contain MG but not any other ingredients that would be harmful to inverts still being branded with warnings that they could be harmful, just as a "just-in-case" since the manufacturer didn't test it on any inverts, and I'm wondering if maybe it could be a similar situation here. I'm having a very very hard time finding information about gentian violet's use in fishkeeping at all though, it seems currently extremely uncommon. What I will say though is that I'm on day 2 of treating my tetras with it, and the bladder snails seem just fine -- in fact today I noticed what looked to be a bladder snail that appeared to be newly hatched (because of its size) that I hadn't seen before that was zipping around the tank without issue. But obviously, shrimp are not snails, and bladder snails are also notoriously hardy little guys, so what I'm seeing right now could easily be totally inapplicable to cherry shrimp. It might even be inapplicable to other species of snails, for all I know. Has anyone else here ever used anything that contains gentian violet in a tank that actually does contain shrimp? Were they okay, or should I make sure to not use it once shrimp are added?
