I'm in search of a buffering substrate that is cost effective. I have just setup several tanks so I don't need to spend a fortune on overpriced substrate. Currently I have Fluval Shrimp Stratum and UPAQUA Aqua Sand.
Fluval Shrimp Stratum costs $19 for 4kg
UPAQUA Aqua Sand costs $40 for 5kg
What is a good substrate for both Neos and Caridina shrimp but won't break the bank.
