I thought so, only neocaridina could tolerate the higher ph/kh of Seiru stone.I’ve pulled my Seiru stone as it’s not good for shrimp. I’ve added peat to my sump to help lower ph as well as shrimp soil to help balance everything out. I also got an rodi unit for water changes because tap water is no good for these finicky shrimp.
I started doing weekly wc’s of 10-20%, and trim the grass during wc’s. Definitely a learning curve with these cardina.
I was gonna try dragon stone but it isn’t great for them either. Most the caridina keepers don’t have any rocks in the tanks that I’m noticing.I thought so, only neocaridina could tolerate the higher ph/kh of Seiru stone.
Ya I’ve lost about half of the shrimp. My ph was too high and the rock may have depleted the majority of the buffering agents in the soil. So I added peat to my sump to help lower ph. I also add black water additive for shrimp to help lower ph. I also added some more soil into my sump. The ro water also allows me to get my new water going into the tank to where it needs to be without a bunch of bs in the water.When you say 'learning curve" were you having losses or noticing the shrimp weren't thriving or just on a journey of discovery and making adjustments as you learn more?
On the subject of rocks, granite is 100% inert so if you wanted to add some rock that would be a good option. You can find some cool colors in the pink/red spectrum that would contrast well with the bright green grass...
