Wire shelves shrimp rack

I got this going at another forum so I thought I will post it here too.
This is just experimentation, Sulawesi and Neos will stay, the rest will be moved to other tanks.The 3 tanks on top have Caridina shrimp, the 3 ones below for Neos and the rest is 1 x Paracaridina, Cardinals, Royal Blue tigers and Malawa.The tank all the way to the left at the bottom is the sump, the water pumped up to the 3 tanks, each tank drips on the one below, each tank has sponge at the overflow to prevent shrimplets from escaping and act as biological/mechanical filter

Surprisingly, the CRS in this set up are breeding and offsprings growing fast, that is PH8 , Temp 80F and 340 TDS, the only shrimp didn't do well is orange Neos, but Sulawesi, Royal Blue tigers, Chocolates, Red cherry, Paracaridina and Malawa are all breeding and berried again.

60 TDS is too low, the breeder is right about cooler temp and low TDS, I think the ideal water parameters are 72F, KH 1, GH4 and 150 TDS.
My set up is just for experiment purpose, don't take it as a guideline.

Those are large kritterkeepers that you can find at LFS for reptiles.

I am going to keep them there for now or unless I find another project to do.
What kind of toxins they will leach? are you sure about that? I am still working on the filtration options but I do have activated carbon in the sump.
