I read about it after I set up Frankie's filter, and when I got Ralph's filter, I just plum forgot (at least those were my excuses).
But last night, Ralph discovered what fun it is to go behind his filter intake again, and again, and again. (Side note to anyone with an FX5: Make sure you take the suction cups off the bottom of the filter strainer. This, I actually HAVE done!). I've seen Frankie do this before, but it didn't worry me too much. Even though she's only 1.5" longer in shell length than Ralph, she's about twice his mass. There's not much that can stop her. I noticed when Ralph was going behind the intake, he had to struggle a bit more to get his "little" body behind it. (Don't worry, there's no way he could get stuck). He was kicking a lot more at the intake than Frankie ever does.
Anyhow, I checked up on them this morning, and there Ralph is, playing behind the intake again. No more excuses! I turned the filter off and took the intake out of the water and let it dry. Took what was left of my silicon (most of it has dried up now), put a thin layer of it all the way around on the intake tube, and put the strainer back on.
To do both filters probably took less than 10 minutes. The turts will be without a filter for a day, but it gives me peace of mind! Plus, it'll give me a good chance to do a partial water change tomorrow.
So the point to my long and rambling story is, if you've thought about siliconing the filter strainer, or even if this is the first time you've heard about it, just bite the bullet and do it now. It'll take 10 minutes to do, and you'll never have to think about "what if..."
