Summary from the old thread;

I managed to destroy my wonderful Taiwan bee tank with a faulty heater that cooked them. I then set up the tank afresh May 2019 using shrimpking substrate, new plants and wood etc. The tank looked very drab from the start and several batches of new taiwan bee were added and died out instantly. Covid came along so I decided I would give up with the taiwan bee shrimp and get some fish instead about a year later (1 kilie and 12 mosquito rasbora). September 2020 I tried another batch of tawian bee but they fared no better and the tank was still very drab looking (and still is to this very day). I very much doubt it is the substrate but won't be using that again but have aquired a large bag of the old type of substrate I used before, but I really don't know what caused the problem, maybe there was some sort of bacterial infection or I accidently poisoned the shrimp, or there was something on the new plants/wood??? The parameters were always perfect and I have to just accept I will never know? At some later date I dumped some wild type red cherry culls into the tank as food for the killie but he didn't seem to eat them (they were clear/brown so maybe he didn't see them) and they seemed to settle into the tank and bred!

Fast forward to a month ago and I decided that now the postal service is better than it had been early in the pandemic, I should maybe try some more taiwan bee as the cherry shrimp had been in there for a year or so and doing well, so I assume whatever the problem was had gone, although the tank is still not as healthy looking as the other tanks using the other substrate! I ordered 15 black shrimps 2 weeks ago and put those in the tank and they seemed to be surviving so earlier this week I order 20 red/blue shrimp and put those in the ttank yesterday. This morning I counted 18 shrimps (about half) so it looks as though it maybe going to work now, the tank is so densely planted that I would never expect to see ALL the live shrimp anyway! The killie fish died a few days ago so he isn't a threat anymore and I doubt the rasboras are either. I am now in the process of fishing out the wild type cherry shrimp as/when I see them!

Here is the link to the full thread about the above but I decided to start a fresh thread from here on,

https://skfaquatics.com/forum/forums/topic/14523-here-we-go-again/

I will keep this thread updated and get some photos at some stage, though the new shrimp are a bit small at the moment.

There isn't much to report on this at the moment, I am 50/50 as to whether this is going to work or not long term. I have seen 2 dead shrimp since adding the new ones and counted about half of the new shrimp bought, that I saw yesterday! This is going to be a long term experiment I guess, the best I hope will happen at this point is that the remaining shrimp survive and reproduce and that new borns born in the tank should be more suited to the environment/water etc.

There is an element of the acclimating didn't go as well/to plan as it should with my knowledge/experience, but I did the best I could, so that is what it is!

Hello again, 

Just stopped by to wish you good luck, but if not, may as well break down the tank and start over completely.

I hope someday I can have a mixed tank as nice as yours.  So far, most of my shrimp babies have been low grade blue bolts.

You are of course right that the tank should be started afresh and if none of this batch survive I won't try any more until I can do a fresh start! I do have the substrate ready to do this but now isn't the time to do it, though I wonder whether it ever will be.........

I am pleased to hear you are getting babies, even if they are lower grade, you are heading in the right direction. Blue bolts are  probably my favourites of the taiwan bees.

I thought I should do an update on this. There are a few shrimps still alive in the tank but in all honesty this has not worked out as I hoped, obviously! I will just continue with the fish in this tank plus the odd surviving shrimps of neocaridina and caridina. I do have the new substrate to start a new tank but that is a bit unlikely, unless I move house at some point where it would make more sense to start afresh! 

Anyway, at this point I won't bother continuing with this thread, unless some miracle happens................

My TDS meter stopped working so I have thrown that away. I had another in my drawer so tried that and it looked like it was inaccurate reading 219 in the taiwan bee shrrimp water so I discarded that as well and ordered a new one which has arrived. I tried the new one and got a reading of 222 in that tank. When I did the usual weekly maintenance and partial change of water I made the usual RO (2 litres) which read TDS 000, and added 2 drops of GH+ and got a reading of 19 which seems to indicate the new meter is correct and accurate!

If you are wondering why I am posting this, it is quite likely the old TDS meter was incorrect and therefore I am wondering if that is why the shrimp didn't survive as it was reading 140 but actually nearer 220? It also means the spare meter I had was probably correct but was thrown out, d'oh!

I may try another batch of shrimp in the future, though a move is likely to happen in the near future so I may wait until that has happened! In the mean time I will try and double check this new tds meter is actually accurate, but it looks likely it is and, it was not a cheapie??

      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???

      I am still thinking it is 50/50 at this stage and will see what happens after another month! Th parameters seem to be slowly getting there, when I tested a few days ago, PH 6.5, KH 0-1, GH 6-7, TDS 150. I have around 10 shrimp left (25 were put in a month ago) but we did have a few hot days which ran together last week which killed at least a few, tank water got to 28 overnight, got a/c during the day, but that requires having the window open for the exhaust hose when running so a bit risky to leave it running all night. I may invest in some specific cooling if this works out for longer with shrimps, but we don't get much hot weather in the UK usually? The remaining shrimp seem fine, swimming about and coming out when I add food. I tried shrimp lollies but they aren't bothered with those at all so they seem to be just a good way of gathering snails to remove and keep their numbers down. If most of the remaining shrimp survive another month I will likely try some more, and by then hopefully ALL the parameters will be good and within the acceptable range as only GH seems to be a bit off. If I didn't have the shrimps in the tank I would try another 50% water change, but for now I will just see what happens in the next month with regular weekly water changes and running/parameter testing etc.

      Looks very nice! Similar scope to what I'm looking to do so am snooping for inspiration!   After another few weeks, how is everyone going?
