important it is you get a really good gravel cleaner that suits your
tank. I
was using a cleaner suitable for a small tank and when I bought the
new 22"
one I'd say it sucked up 400% more junk on it's first use that the
little
one just wasn't able to pull up out of the substrate.


If this is true, don't you think people who use soil or even mammal
dung in their tank substrate would have massive water quality problems?
A large portion of the planted tank keepers do no deep gravel vac'ing
at all.
