CRS and whether to use RO water to maintain water parameters

Recommended Posts

Hi 

 

I'm relatively new to shrimp breeding.

I have CRS - 6 and Cherry Reds - 4 and a few Ghosts  -3  and a have just aded 4 Taiwan Bees - Taitibees

Currently I'm using tap water after I've added Prime and aged it  with an air stone going for a week or so :-) 

My GH is around 3 and KH around 4 usually TDS I keep < 150

Tank is a 14 Litre Nano and I keep the temp to 22.5 degrees C

I was wondering if anyone could let me know their opinion  regarding using RO water and adding a minerals like Salty Shrimp - which I have noted people mentioning

Thanks

Roscoe

There are no "Cherry Red" shrimp. There are "Red Cherry" shrimp, though.

CRS = Crystal Red Shrimp (Caridina)
RCS = Red Cherry Shrimp (Neocaridina)


Your GH is too low for your shrimp (you want at least 6 GH) and the KH is potentially too high for the Crystals and Taitibees.

The Cherries and Ghost shrimp can do just fine on sand or gravel substrate with at least 6 GH and a pH of 7.0-8.0. but the Crystals and Taitibees would do best on a buffering substrate with remineralized RO water using GH+ only minerals. Ideally, you want a KH of 0-1 (typically 0, but 0 and 1 read the same on the API tests), or a max of 2, with a pH of 5.0-6.8.

 

Would recommend setting up a separate tank for your Caridinas so they can live in preferred parameters.... unless they came out of Neo type parameters?

Do you know the parameters they were raised in?

It's the only way to go if you want full control over what is in your water and control of the water parameters. Rain water is another alternative.

Shrimps and many softwater fish (generally) like low pH, low TDS water. And for many people this is almost an impossible task with their tap water. pH comes out at close to 8.0 and TDS is 80-100, at least the last time I tested my tap water here in Sydney. That 80-100 TDS is made up of a lot of unwanted chemicals and metals.

If you also knew what was in our tapwater, you WILL want to swap to use RO or rain water and add your own minerals using products like Salty Shrimp.

Wow

Thanks for the feedback. I need to get a separate tank going ASAP. I am off to the LFS to get one and setup a RO + Salty Shrimp..

Thanks so much for your help

      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.

      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.

      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?

      One interesting thing he mentioned was "Bacteria pressure", which I guess just means number of bacteria around.  Yet I see all these other videos from shrimpkeepers bragging about how much bacteria their filtering system holds. Also interesting is no mention of using anti-biotics to treat bacterial infection.  I think that has fallen out of favor recently.
