wachu Posted May 21, 2020 Report Share Posted May 21, 2020 Hi, first of all - im new at this hobby and i just registered (hi everyone!). I have two problems with my 20L tank - one leads to another (i hope). First my water info: Ph - 7,0 NO3 - 5ppm GH - 5 NH4 <0,05ppm NO1 <0,01ppm KH 6 24C temp water conductivity: 300 uS the tank is 5months old and i used H.E.L.P. Advanced Soil PLANTS for my soil. I use RO water that i minerlize with mineralitor for crystal red shrimps. For filtration i use Fluval C2 filter with prefilter, cotton, sponge, seachem matrix and seachem purigen. The problem is that something is increasing my GH and uS parameters - i did 50% water change yesterday and today parameters have change GH 5->6 and us 300->360us (im sure it will be more by tomorrow). Because of this all my attemps in breeding crystal shrims have failed. Im attaching my tank img. I would really appreciate the help! Quote Link to comment Share on other sites More sharing options...

OblongShrimp Posted May 22, 2020 Report Share Posted May 22, 2020 What are the stones in there? They are likely the issue. Quote Link to comment Share on other sites More sharing options...
wachu Posted May 22, 2020 Author Report Share Posted May 22, 2020 Hi, thanks for replay. These I bought as "scenery stones" - i took them out yesterday to see if anything will change. Quote Link to comment Share on other sites More sharing options...
OblongShrimp Posted May 23, 2020 Report Share Posted May 23, 2020 Your welcome. They look like Seiryu Stone (couldn't remember the name last time and couldn't guess close enough for google to know what I was talking about). If that is what they are they definitely impact water parameters. You can also put them in a bucket of water (RO is probably best) and see if they change the parameters.

CVilleShrimps Posted July 1, 2020 Report Share Posted July 1, 2020 Definitely the stone. ^^ Agreed with OblongShrimp. SJ Quote Link to comment Share on other sites More sharing options...
