Thanks for the informative response on filtration Kathy.
Keep making your discus videos. Im subscribed to your YouTube channel and I enjoy watching them .The last one with the needle feeding was a bit scarry though :-) .
I hope for a full recovery with that one , eventhough he is not the prettiest discus you have :-) .
I was amazed by the courage of the care giver as well as by the amount of the medicine cocktail applied .
It was surely educational and informative video anyway. TFS.
