Hi,
quick question, I have built myself a waterfall for my pond (will try and add a photo). I have a liner behind the rocks but wanted to direct the flow of water down the waterfall so fill all the gaps using mortar.
question: do I need to seal the mortar off with a pond sealer product or will it be ok to leave as it is? I don’t want to harm my fish and someone told me the mortar or lime in the mortar would be bad for the fish?
I have done some searching but most threads are based on full mortar or concreate waterfalls, mine is just mortar between the rocks to seal the gaps.
please can someone help?
many thanks
Ricky
