Thank you for the reply this is what I was hoping in a real world case. I have no problem running them at a high enough rate just don't want it so that fish would try taking a chance.
Also I have plenty of smaller snails and a couple small urchins I don't want to get pureed.
My tank is 4 feet so the narrow guard just isn't going to do what I need it to.
A couple of my fish will still get too close but nothing that I fear will harm them. My Gold Lined Rabbitfish being the more aggressive at the cage cleaning. I get a bit nervous when it does it but in the few months that I've been running the Tunze 6105 I've have zero issues. Just the flamehawk as I mentioned but keeping the motor running at low seems to have stopped that.
I wish the motor could spin backwards as I think it could help in this area. Along with better push, pull, water movement without coming to a full stop. Maybe the stream 3's of theirs does this and I bought the wrong product.
In any case I really like the Tunze quality so happy with the purchases.
