Finally set up the 30L Shrimp Tank

I have finally got around to setting up my old Taiwan Bee shrimp tank (30L) which was shut down when I moved just over a year ago.

I am using Tetra Active Substrate (clay based granules) this time, which doesn't buffer the PH but I will be using remineralised RO water once fully set/sorted. Eventually I hope to keep the Taiwan bee shrimps again but won't be rushing anything at this stage, I will see if I can get the water parameters right and try a batch of 10 (cheap) crystal red shrimp in a couple of months and see how they do for 3-6 months? I will keep the tank simpler this time with a lot less plants. The substrate is obviously releasing nutrients into the tank at this point. I added 50% RO water and 50% tap water (only using part tap water for the start up, will always use RO from this point) and next day parameters were, TDS 232 (200 the day before), GH 9, KH 6, PH 7.5 so is way off at this point but I will do a 50% RO water change in a week and hopefully it will be going in the right direction, not rushing? Tap water here is dreadfull, PH 8 TDS 300...........etc

I do still have a new bag of the JBL substrate in the cupboard but decided it needs a bit too much prep for me for the moment.

If it doesn't work out for the shrimps then I will get a killifish and dwarf Rasboras as I did before (or other fish that suit the parameters if they are off), but I will be taking it very slow with this tank this time. In reality it is unlikely I will have Taiwan bee shrimps before autumn even if everything goes well but hopefully there will be crystal red shrimp for the summer?

I will keep testing for the 'cycle' but as the PH is likely to drop a fair bit and as discussed with beanbag on here before, that may not be as straight forward as with a 'constant parameter' tank, but anyway, no rush.

How exciting!!!

I have just decommissioned 2x 2ft tanks.

Been debating with myself whether to set them up again or just leave them empty.

But looking at your new tank is giving me ideas.

I'm not gettng too excited at this point! The water is way off but I plan to do a 50% water change at the weekend with pure RO water which 'should' bring the parameters nearer to those required. I do quite like the simpler tank setup, the plants came from the betta tank where they had grown too big, so that tank also looks better and the fish has more swimming space. Definitely slow and steady this time, one step at a time. The tank is opposite where I usually sit so it will be good if shrimps work as I will see them much more often than before and in a sparser tank will be able to see more, so keeping my fingers crossed. The substrate was meant to be neutral and ready to use immediately and not buffer the PH, but it must be releasing minerals etc, not a problem at this point but I'm not 100% convinced it will work with the shrimp longterm, but it is still very early on?

What did you have in the now empty tanks? Any ideas for the tanks IF you do decide to keep them going, anything tempting you?

One was a hospital tank that I could not be bothered maintaining any longer.  

The other was a fry grow out tank, which had Longfin White Cloud Mountain Minnow - Tanichthys Albonubes, that have now grown up enough to be moved into my main fish tank.

I have not settled on any specific ideas yet. Maybe an Australian native tank with one variety of Blue Eye Rainbow fish. Maybe a Killifish tank.

Good luck in your new tank.  My only suggestion is to NEVER use tap water and always use RO + remineralizer.  Many long-running tanks can suddenly get nuked due to something in the pipes.  (In particular, I'm thinking of that youtube guy Foo the Flowerhorn)

It has been a few weeks now and I have done a couple of large water changes. I tested the water parameters this morning, GH6 and KH2, TDS 140 and PH 7.5. Obviously the PH is off but there isn't anything in the tank that should cause the PH to rise to this figure so I will just run the tank for another month with 10% weekly water changes (probably just with RO water) and see where we are at that point. The RO water tests at PH6, and the KH and GH in the tank could come down as they are at the upper limits for Caridina shrimps! There are only about 10 very small snails in there at this point, but they seem to be doing well enough.

Time for another update!

The PH this morning is 6 and KH 0-1 (you can't measure zero obviously). I plan to check everything tomorrow and then a water change on satuday. At the moment the TDS is 190 which should drop to 170 after a water change and then 150ish after the following/next weeks water change. Last time I checked GH it was 6, but again I will do ALL the tests tomorrow. I had to resort to using a PH/KH- product (AQUACID) to get to where these parameters are now but as the water I use has PH6, GH0 and KH0 I assume/hope I won't need to use that from here on, but will see if the parameters stay stable for the next week and have a PH alert disc in the tank which should indicate any significant change. I don't like using these sort of products as a general rule and wouldn't if there were any shrimps in situ and that product has raised the TDS at about .5TDS per drop.

I may well order some blue bolts towards the end of next week (the road to the house will be closed for a month from 3rd June so it is next week or wait another 6 weeks) and see how that goes. I plan to drip acclimate them overnight this time so as to not rush that as it shouldn't get cold indoors overnight anyway this time of year. This all depends on the tank parameters staying stable for the next week (aside from the mentioned TDS adjustments with the water changes), though the GH  may drop a tiny bit with using just RO to reduce the TDS but that is fine, and even could be a bonus.

I did manage to find some nice floating plant that I had before (good old ebay), and will try and get a photo of that at some point to attach, Azolla red I think it is called?

Anyway, keeping my fingers crossed for now but all appears to be going well at this point! Snails seem to be doing well at least.

      That shrimp itself survived the molt just fine, but left about half dozen eggs still in the shell. I haven't measured KH in a really long time, but assume it is zero since I don't have any rocks besides a few small pieces of lava rock.  Maybe you have unwanted rocks in your tank?  My tank is the "long" style which I really like because I have a HMF on one end, and a pump outlet spout that shoots water all the way to the other end.  I have no idea how many shimp it can support because I don't really understand waste management in a tank.  Shrimp poop eventually turns into mulm, but then what?

      Thats a great photo, beautiful blue bolt, I hope it survived the molt without dropping the eggs! I think I can just about see some black dots (eyes) on the central egg but can't be 100% sure. I used to (and plan to again) do weekly water change of 10-15% but if you do too large or quick (not drip in new water) that would likely trigger a molt. What KH are they in, my new setup is sitting at (and refusing to budge) KH 3 and PH 7.5 so I may have to settle for neocaridina shrimp this time as opposed to the caridina I want, though not looking/deciding just yet, give the tank a bit more of a run in! Tap water here starts at kH 14, tds 320, when filtered goes to KH 0 and PH 6 but when put in the tank keeps going to KH3 and PH 7.5 despite 3 x 50% water changes???? You may be at 'maximum capacity' with only 20L tank especially if the tank is a cube type rather than shallow type?
