How do I Keep From Overfeeding?

Just a note on that battery vacuum... I had/have one of those. I'm not sure what other people's experience with it is but I haven't used it in years.

The filter bag attaches to that little thingy sticking out just below center (where it narrows) and from center down must be under water level for it to work. When the vacuum is running, it creates quite the suction/blow out, the little bag puffs up and larger debris is very efficiently collected in the bag, and water is blown through and back into the tank. I found the bag (or any other I tried to adapt) did not collect minute particles (or else the suction process and whirling around in the bag breaks it down a lot, like a mixmaster) and in a very short time the water in the tank looks horrible. It does get filtered by your other filter and settles, of course, but there is no way you could do the whole tank in one shot and still see the fish.

Dabbler II, do you actually have one? How does it work for you?
 
I got one last night. Its made by Profile I think. It is trash. It is not worth the $3 you would pay for a small siphon type vac never mind the $21 I paid. It will be making a return trip to the Petco it came from.

I didn't expect anything amazing but it wouldn't suck with any consistency or strength. The only way to get it to pick up anything was to take the cup attachment off and to vacuum with just the straight tube. Then it worked too well and picked up every piece of gravel it found. Complete garbage.

If anyone has any good experiences with a particular battery operated vac or one of the air powered ones. I'm all ears.
 
I am not sure if this is the one I have. But the one I have works good, I never had a problem with "dirty water" or it not sucking up the "stuff" I did like it when I used it. I don't use it any more because I have found better ways to clean my 120 (the vac was only 18" long and my tank is 24" high I had to modify it to get deeper). I think my wife still uses it on her 20 gal tanks every once and a while, I'll see if there is a name on it and I will pass it along.
