Has anyone had an interaction problem with lead Plant Weights and shrimp? And if so, what did you do to fix it?
Prep-purchase, I did as much googling as I could and the overwhelming response was lead weights specifically sold to hold down aquarium plants are completely safe with shrimps including Amano Shrimp. I used six strips and within a few days, all dozen-ish Amano shrimps went missing or died. I'd like to know what is likely the cause... hoping to rule out the weights. Unfortunately, no other changes were made to this tank in the recent few months so the weights are my only suspect.
Post incident, I did find a short blurb that claimed lead weights are fine except when CO2 is used but no other information or reference was given.
Any experienced insights on any of this would be very much appreciated.
The tank is 75 Gallons, heavily planted, light CO2, Aquarium Co-op Easy Green & Easy Iron dosing, a mixed bag of ±50 small- & ±8 medium-sized community fish that are thriving, tons of tiny pond snails (that were unaffected), UV light bulb inside hang-on-back filter. The tank is about 8-years old, well-established that up until this occurrence, has thrived.
At the very least, Thank You for reading. 🙂
