Two tanks.

Hi, I've been keeping red cherry shrimp only since last October and had some success in my Nano Cube. I started off with ten shrimp and now have around a hundred. I got so many that I decided to get another tank a bit bigger and to keep shrimp in there as well. I transferred around 20 shrimp to the new tank after cycling and checking the water parameters. Here's the thing, the water in my Nano is now cloudy and I can't seem to clear it. I've stopped using my tap water which has a TDS of around 430 and started using RO water. Everything thrived when the TDS was really high but now I have the cloudy water issue. The shrimp in the Nano are still very active there's loads of babies whereas the shrimp in the larger tank are slow moving and fairly lethargic. I have an active substrate in both tanks.

Should I just leave well alone with the cloudy water, I've changed my filter media, and will the shrimp liven up when they settle? They've been in for around two weeks now. Thanks for any advice.

The 2 cloudy water I have had is Green, which is an algae bloom so the water is probably too 'rich' due to overfeeding etc, or White, which is a bacteria bloom, and that usually only happens with a new tank that is cycling. It would be a good idea to have the old and new filter media in the tank (for 2 weeks) when you change them as the new one won't have any bacteria. 

The newer tank won't be as settled as the older one so may not have much biofim? Have you reduced the feeding in the old tank to allow for the reduction in number of shrimps? Are you using zerowater and GH/KH+?

I wouldn't worry too much if you aren't losing any shrimp, they may just take a while to get used to their new home and feel safe, they feel safer with larger numbers so it makes sense that the small tank with lots of shrimp is more active. I assume the water parameters are the same in both tanks?

Thanks Simon, the cloudiness is green and I think it is due to overfeeding. I have two filters in each tank, sponge and corner filters. I’ve stopped feeding the small tank for a few days as there’s loads of biofilm for the shrimp and it does appear to be clearing slowly. 
I’ll be patient and see how the tank develops. 
Thanks again,

Sonny

      We just had another 3-4 hot (for UK) days where the tank seems to have gone up to 26 and I think no shrimp died this time, though last time it got a bit higher the smaller shrimp died off so I guess they are more sensitive to the heat. I took the cover off the tank so that any heat can rise. I have just tested the parameters and they seem to be great, Ph 6.5, Gh 5-6, Kh 0-1, TDS 134 so aim to stop using unmineralised RO water from here onwards. If the remaing shrimp seem ok for another 2 weeks (as they have for the past 2 weeks) then I will likely get one more delivery of about 20 shrimps, 10 red wine, 5 panda and 5 blue bolts???? The shrimp that have survived so far are the blue bolts, all the pandas died off but they were the first added when the parameters were further off, and about half the blue bolts also died but they were very small  ones mainly and as mentioned, I think the heat did them in. So, it is looking quite hopeful at this point but I will make that final decision at the end of the month. If it is still going well and there are no more deaths I will order some more shrimps and look into getting some sort of fan cooling setup for future hot periods!  How is it all going your end beanbag? I think my Betta won't last very much longer, he is just sitting at the bottom and won't eat, lt can't be the water getting too hot as the shrimps are fine and the water likely only topped out at 28 degrees max. as with the other shrimp tank, as they are next to each other? There isn't anything visibly wrong with him other than not eating or swimming around as he used too.

      have a fan blow across the top of the tank, or get one of those U-shaped air conditioners that allow you to keep the window mostly closed

      I just watched the video again. With that tank I would take 1 of the sponges and put it in the left compartment (where he put the heater in the vid) and the heater can go in the middle section with the other sponge, so that would work well and be very simple and no extra costs or modification involved. The water level in the back drops either because the pump is set too fast (if it is adjustable) or mostlly just because the sponge directly behind the inlet slots is getting blocked. Somtimes just pressing the sponge insitu at the top will blow some of the gunk back into the tank, but you will probably need to take the sponge out weekly to clean it, though I imagine you would probably do weekly water change/maintenance anyway. The tank in the video is also quite good because the back is covered so that will help with reducing evaporation from the back working part, mine was open/uncovered at the back so evaporation was more of a problem. I freaked out when I saw the level drop in the back the first time, especially as I had a glass type heater in the back! If you only very rarely need a heater then you could just put that in the main part of the tank on those rare occasions to be safer? As you say, you have time to see if you even need a heater but I suspect you won't as indoors will be warmer than the outside temperature overnite, and I have seen vids on youtuube where some Australians keep Neocaridina shrimp outside all year with no heaters in huge tanks or even ponds, and I doubt there is anywhere in the world where the temperatures don't fluctuate between night and day so all creatures must be ok with that (within limits of coarse).  My problem last week was the same only opposite, overnite it dropped to about 13 degrees outside but inside overnite it rose to 28 because the sun had heated the roof etc all day, so I did lose a few shrimps then (but they are Caridina so not as adaptable or tough as cherry shrimp), only babys though strangely? Of coarse, it's your winter now, whereas it is our summer. Do you have A/C in the house for the summer, even Neocaridina won't survive much over 30? I only have a portable room one which requires a tube out of the window hense I couldn't leave it running overnight as it is a ground floor room!

      Thanks for the response and interest! I'm planning on ignoring everything about the filter media provided and will do my own thing. But yes, a simple idea to save shrimp is put the filter right next to the intake bit.. I hadn't thought about that and was already thinking about adding mesh... your idea is much better and straightforward.  In regards to heater, where we are in Australia it gets 40 degrees in summer, but we had -7 last week at night.. this morning was a much warmer -3! The heating in the office is a bit whack too... it seems to be boiling hot or freezing cold, so the heater is something i'll just play 'wait and see' with. I don't propose to stock for a while anyway so will have substantial time to monitor the temperature and see if/how/when a heater is needed.  I saw a short youtube video on the water level at the back.. I'm glad I watched it / you told me because if I went in without knowing I'd be freaking out the first time I noticed it.

      I had a very similar tank to the petworx one and they are very clean to look at and easy to maintain, but obviously you are losing some volume/floor area for the shrimps to inhabit. You will probably need to work something out so the shrimp don't get through to the back area, especially babies (sponge behind the slots etc) - you may be able to just move part of the sponge to that compartment looking at this video:  I would only get a 25w heater, I learned my lesson when my 50w stuck on and cooked the shrimps in my 35L tank. 25w should be adequate as you have a much warmer climate, in fact do you really even need a heater? One drawback with this type of setup is that the level of water in the back can drop drastically when the sponge starts to get clogged, though this is mainly only a problem with the heater which may break in insuficient water, or the pump in really severe circumstances. You will need to clean the sponges at least weekly.  The level drop in the back can look quite alarming when you first see it happening.  The other makes may also have the same issues? I would have thought nearer $250 as it already has a light and pump, and if you don't need a heater? I tried the 'let the idea fade away', but it keeps returning???
