    I’ve been keeping koi for a few years and have been highly fortunate never to have a casualty. I recently did a 50% water change and hoovered the sludge from my pond—the usual clean-up after winter. I have replaced some filters by dipping them in the previous pond water. The pond is 2.4m x...

    Can I use this marine sand in my freshwater planted tank?

    Recently bought a bag of marine sand to use as substrate for my freshwater planted tank. I'm worried that it might not be suitable for the plants and fish inhabiting the tank. Can someone clear my doubts?
