      Hi I signed up awhile back but this is my first post so I hope I'm in the right section. I've been keeping crs/cbs for a couple of years now, starting with a dozen and now have approx 200. I have a large 200lt tank and use fluval stratum. My parameters have always been pretty steady, tds 130-150,  ph 6.7-6.8, GH 3-4 and KH 1-2 and have had great sucess but over the last few months my KH is reading zero and the PH has gone from 6.8 to 5.9!! All shrimp are still doing well and no noticeable deaths but the ph drop is concerning. Is this directly related to zero KH? (No buffering) Any advice on the cause and any action that I should take would be very much appreciated. Thank you

      I have had a 20 gallon RCS tank for 3 years now.  I have moss balls and some JAVA moss, drift wood, and mineral rocks.
      Only RCS in the tank and some soft shell snails I have in there I breed for my fresh water puffer fish in another tank,.
      My issue is that the shrimp live 1-2 years and they breed just fine but I never see babies.  I see plenty of eggs but never babies.  (Well 1 or 2 a month maybe but they disappear)
      The adults keep going just fine until they die off of old age or something else.
      I keep about 100 shrimp in the tank and have to replenish 50 every 6 months about.
      Water Temp I keep about neutral. 
      PH- 7- 7.2
      I use distilled water or sometimes Reverse Osmosis water because our tap water goes through a water softener which puts a LOT of salt in it which makes TDS very high so I try not to use tap water at all.   
      I feed every 2 days with Azoo or other good food and not much.  Its all gone by the time I feed again.
      I do add some powder food for the babies and a shrimp bacteria powder (just started that about 6 months ago but has not helped or hurt)
      Someone told me due to the distilled water my issue is LOW TDS.  So I bought TWO different meters.  I tested the distilled water and its about zero which is correct.  I then tested my water and its about 700.   I do top offs and just did a 20% water change last weekend with distilled water.
      So is that the issue?  Should I pull out the mineral rocks?
      I am thinking tonight to take about 8 gallons of water and drain the tank down about 40% and then fill with the distilled water.   I can repeat the process in a week and once I get the TDS under 150 I can add a little shrimp mineral to get it to the 200 range.   The reason I am saying that is the TDS could be bad TDS and not the minerals they needs.  I ordered some Salty Shrimp Mineral which I heard was good.
      Should I just give up?

      One of our sponsors, @Filter Systems Australia are seeking an expression of interest regarding a range of filter media they are considering carrying. If interested post here. Current prices are as follows:
      Mafian Stone: $15/Kg Tourmaline: $25/Kg Neg ion: $30/Kg FAR : $25/Kg But this will change (go lower) subject to demand and our SKF discount.

      I use an American Filter jug by ZEROWATER to get RO water. This is obviously the easiest route for you as it is available everywhere in the USA (Walmart etc) and you just use tap water and will be much cheaper there as it is an American product, they have a USA website you can get details and buy from as well? I then mineralise the water with the usual shrimp products! I hope this is of some help but I don't use canister filters so can't help you with the rest unfortunately! Simon

      Hello shrimpkeepers, I decided to get a canister filter and keep a fry screen on the intake. I have yet to set up. I also set up simple PVC pipe water bridges. It was so simple. Thanks for the idea! im hoping that the water displacement from the canister filter’s intake and output tubes (each in separate tank) will move water and temperature through the pipes by balancing the water levels.

      Thanks sdiTBfan, I’m setting up a one gallon tank for the nerites with my daughter. We’re going to slowly add a bit of reef salt each week and monitor gravity levels. We’ll see if they breed and hatch. if they do, I hope the First Bites fish food will work for them. I’ve read the snail larvae like fish food and especially Artemis/diatoms, things baby fish like. I’m a little worried because I saw copper as one of the nutrients. Perhaps too negligent an amount for damage, but I don’t think I should be feeding any copper to snails! If anybody know I’d any great snail larvae food, please let me know.

      Hello, I am currently keeping and breeding a variety of neocardinia species, snails, crawfish, and Cory catfish (across different tanks). All being very hardy, they have been lucky to survive my TDS negligence, as I’ve only recently gotten a TDS pen. I live in Chicago where the water is pretty hard and a TDS read of my high quality tap filter’s water output is around 160 (before I let it dechlorinate- not sure I’d this makes a difference). Additionally, I obviously have to mineralize this to get to the right KH/GH levels. I’ve got current levels between 250-300+. I would like to raise Caridina species but first need to dramatically lower TDS. I’ve bought a lot of R/O water by the gallon; such a waste of money and plastic. I sell the shrimp, but worry that if I buy R/O water for every water change, it will turn into a money pit. I also bought a canister filter since vacuuming the gravel was always laborious and disastrous, in part thinking with certain filter medium I could reduce TDS. I’m not sure that was accurate. Does anybody know if I can use the canister to filter out dissolved solids somehow? Has anybody heard of any cheap DIY/marketed inline filter that I could add to the canister to help? (like the one my furnace humidifier uses, lol) I could also get an R/O buddy filter, but that’s expensive and I’m not sure how often I’d have to pay for replacement filters with my local TDS levels. Curious to heat anyone’s thoughts?

      Oh, I do have some people/ friends wanting to buy, but I can’t with a clear conscience sell/trade until I’m sure they are 100% healthy. Also, I need to rebuild the population first. I don’t mind any color babies. I know I’ll get a broad mix, but I don’t care. I’m not looking for a pure line, anyway.    I have no plans to change the treatment regimen at this point, aka add any new treatments.     As far as the Galaxy Rasboras, it won’t HURT to get some. Yours might act differently than mine. And if the population is growing and you have good hiding places, you should be ok. It doesn’t take long for the babies to be too big for them to consume.
