      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.

      But the shrimp will be thinking otherwise. Look at all that yummy brown diatom!

      I am old school like that too. I prefer the classics patterns/colours. And I try very hard to not create further hybrids. I want my CRS to be CRS. My tigers to be tigers. etc...   @kms, all the more to support the site and sign up as a paid member.   @Cesar, what's the deal now with the new forum update? Has the photo size limits been changed, and if so what is the max for regular members?

      Thanks for that, it helps to know that it is probably going to be fine with time. I tried a different substrate this tie so that is all I can put it down too! I will revert to the JBL in future as this hasn't happened with that? I don't use any plant ferttilisers, and as above have never had to with the JBL substrate. The JBL is primarily a plant substrate and the shrimp king is primarily a shrimp one I guess, though they both seem to do the same buffering /softening etc? There will be a bit of a delay with breeding I expect as they don't mature until they are 6 months I believe? Again, thanks for that, it helps to know what someone else thinks and the tank has improved (hard to believe from the photos) going a bit greener and the stringy algae virtually now disappeared. Also a few new leaves on some plants etc. I just checked the water parameters and they are spot on! Simon

      The new update has reduce the photo size to 1.67MB for me, and all the photo taken with my phone is over. My pinto only cost less that GBP 4, as for the Red Wine, its 5 for GBP 10.20, any extra Red Wine will be GBP 2 if more than 5 is purchased.

      New tanks often go through a brown diatom phase and its just a waiting game before the diatoms naturally senesce.  Ride it out. The shrimp will certainly help clean it up and I'd wager that diatom rich biofilm is good nutrition.  You'll have shrimp breeding before you know it.  There is certainly a good complex variety of habitat for them to explore and exploit. Are you using any plant fertilisers yet?
