I received a disturbing email from a customer recently. One of his Filter Starter Balls escaped from his filter while he was cleaning and before he could retrieve it one of his fish swallowed it. Unfortunately, the next day his fish was dead. This took me completely by surprise.
I expected the ball would have passed right through without causing any harm. I’ve lost balls into my pond before. It maybe that koi and larger fish can handle the balls with no problem, but from now on, I’ll be more careful.
When using the Filter Starter Balls, I’d suggest you place under the media so they won’t float away and leave the filter. If you are not confident you can retain the Balls in the filter, then I’d suggest you place them in a media bag.
These small 400 micron Media Bags are ideal for this purpose.
