TDS adjustment (lowering) Reassure me!

Recommended Posts

OzShrimp

Just did my weekly water change and my tds was 175ish howeer its normally kept around 155. So anyway i ended up putting in like 30 litres of straight RO Water and brought it down to about 160 but i couldnt remember if this was all good to do lol.

.

My shrimp are pretty harder and all my water changes are done by just pouring the bucket in and dont have issues but wth RO water straight need some reassurance lol, would hate to see like 100+ CRS die -nervous laugh- lol

Should be fine dude, just like ripping a bandaid off quick, little bit of stress but only for a short time. :thumbsu:

That's how I drop mine too although if for some reason -lots of evaporation etc - the TDS needs to be dropped a lot I will put a small amount of Salty shrimp in the new water just so it isn't too much of a difference and you see how well my CRS tank does on it. Generally though it's just straight RO done with a slow pour from the bucket -my shrimp don't get the drip treatment for water changes!

Hi Guys,

My TDS has crept up to 230 with a gh of 8 in a 60l tank. Do you think I should just do a large water change and try and bring down to say 170 with plain RO water?

I would be doing that slowly only because its a fairly large drop. Some might say it will be fine but to be on a safer side i would be doing it gradually.

Hello @larrymull,

All my tanks TDS were a lot higher then I usually keep them when I got back from my Holiday. When this occurs I don't got for a plain RO water change but I add half the amount of SS I usually do.

For example I keep my tiger tank at 180 so I will mix my RO water up to 90 TDS. I will usually change between 10-15% each week until the TDS is back to where I want it. Once it is back to normal I just do my usual water changes.

      Sorry to hear you have lost a shrimp. How many are there left in the tank? I wouldn't act to hastily and start treating for something that may not be? Maybe it just died and you will never know why if it had no symptoms? Just keep a close eye on the rest for now! Maybe the BKK weren't very healthy to start with if they hadn't grown as expected, though also there may not have been sufficient food, but that is less likely if the others in the tank have grown! I would feed the shrimps as the grazing area is fairly limited (I assume this is your 80L divided into 4) but sparingly, maybe twice a week. Crush up a pellet into almost a powder, then dip a pin or similar a couple of mm in the water, then into the food, then back in to the tank will give them something different to eat to supplement their diet. I would check the temperature of the water as well as when my old setup overheated they started going an orange/pink colour? It is good that you obviously spend time watching them as they are fascinating to watch and very calming!  Simon

      Perfect. I've got a spare heater, can source a tank and filtration, have cycled media, and have a simple light if ambient light isn't enough.  Pretty random question - are sponge filters super noisy? I've never used one with an air pump, and the qt tank would go in my bedroom; but only if I could actually sleep 🙂. Otherwise, is it cool to turn off a filter at night? Cheers

      Usually a week or two should be enough with careful observation to see if any symptoms develop.   No. But it depends on the filtration. If you use a mature filter, then you don't need to cycle a quarantine tank for very long. I just use the water from my water change to fill a quarantine tank. And some old filter media floss from a mature filter in the quarantine tank's canister. The quarantine tank is very basic, no decor, no substrate, nothing. Except maybe some lights to check for diseases after a week or two. You can get away with lights, and use a hand held torch even.  Just a heater.

      Thanks for the advice guys, I really appreciate it! As for the details, the tank is my 110L community, and while none of my fish are especially expensive or special, but I don’t want to lose any or have to rescape. The reason I was hoping to avoid qt is bc I don’t have a spare tank or filter atm. I think I will qt I think. How long should I do it for, and do I need to cycle the tank very long?

      Hello folks, This is in regards to my TB tank that has had shrimp for about 2 months now.  The shrimp came in two batches from different vendors - one was two BKK and the other was a bunch of RWP and BB.  Everything was going well for about 2 months with the shrimps actively grazing around and suddenly I found one of the BKK dead and upright in a corner of the tank.  I usually do a check-up on the shrimp every day and the only time the shrimp are inert is one day before and after a molt.  In the past when I had shrimp die for various reasons they would be inert for a few days prior. The water parameters are the same as usual: Amm/NO2/NO3 = 0, ph = 6.0 or a little lower, GH 5, TDS 110 Using RO + SS GH+ and I did a 15% water change 2 days ago, dripping in the new water. I haven't fed any pellet shrimp food for a while because there are still lots of patches of algae in the tank, plus one IAL, plus they finished off a mulberry leaf 2 days ago. Nothing looks odd on the dead body of this shrimp (no real color loss) except the clear parts like antennae and tip of tail are a little orange.  (I think this is typical of shrimp that have died?  Or a molt shell once you remove it from the water and expose it to air.) The only odd things about this shrimp are that in the 2 months, it molted a few times but never grew much (or at all) over the original 1/2" size.  About a month ago, the white parts of it started turning blue.  The other BKK that came at the same time also either hasn't grown at all or maybe just a tiny bit, and only has little patches of blue.  The other batch of shrimp from a different breeder (RWP and BB) have grown significantly over this time. Anyway, the rest of the shrimp seem to still be doing well and actively grazing.  (Actually, two are acting quiet, but it is still within the pre-molt time frame) I hope it's not bacterial infection, but what can I do to prevent / prepare?  I have available: Dr Tim's Eco balance, Doxycycline (fish med), oregano oil, melafix, H2O2.
