Nano fish/ shrimp tank

Cheapest option is limestone rocks from the garden supplier.

You can add KH generator crystals, or add some buffering rocks, crushed coral in the filter. Add a little test in a week, add a bit more etc until you get a stabilised increase. Don’t add all at once or the shrimp will die.

Thank you! I will find some and add to my tank. I will give an update in about a week

I think I need to do it too now, my KH generator crystals are not enough and my basalt river boulders are not buffering as much as they used to

What are you going to try? And what size is your tank?

 

[RyanScanner]

My main tank is 1200ltr or 300g so buffering crystals gets expensive. I’ll try limestone or crushed coral in filter bags I think

I currently just put KH Generator 1 tbs per week in my 2 shrimp tanks both 30G

How 'bout seashells?
A sunbleached conch shell or oyster shell (mass of?) might be lovely & get those buffering & micronutrient jobs done nicely.

My first horribly overpriced blue shrimp trial (same sort of thing as OP, but on as island) has now moved from the 1gal Tupperware to the 20gal with lemon-tetras (another long-term & totally unsuccessful breed-trial). Also ostracod & a mystery snail. System-habitats include long-dead branching coral, fully rotted/clean sea-sponges (various) & various water-plants including rooted overwater passion-vine, along with urchin casts, freshwater mollusc shells various, a bit of Halimeda "oats" sand & coconut & bamboo halves: a veritable cornucopia of graze-able surfaces.
