Wet & dry filters ?

[martin]

Does anybody have any comment to make on wet and dry filters, both for
FO and reef systems ? Seems to be a lot of conflicting information
about them and I'm not sure whether to invest or not.

Depends.

For a FO tank they work very well, for a reef tank, they are not good,
because they work very well. The wet/dry filter is a great filter for
part of the nitrogen cycle, it handles the ammonia to nitrite to nitrate
very well, but it quits right there. In a FO tank, the nitrate is not
to bad most fish can handle pretty hight levels of nitrate. But in a
reef tank, nitrate is algae food, and is an irratent to many
invertabrates. So you want a low nitrate level, if you use a live sand
bed and live rock the system will not only convert the ammonia to
nitrite to nitrate, but it will also in the areas of low oxygen in the
rocks and lower sand bed levels convert the nitrate into nitrogen gass,
so you have much lower nitrate level in the aquarium, and less algea growth.

I would syat away form them. If you stay in the hobby you will regret
spending the money on one

Fabulous explanation. I've seen them work well in reef systems, but
they *can* indeed cause higher than desired nitrate levels.

Hi KIm,
basicly I agree but would point out that Nitrate is just as
much 'algae food' in a fish only tank as it is in a reef tank, also
marine fish are far less tolerant of Nitrates than fresh water fish.
Why install a Nitrate factory in the first place ?.

A true "has been" in the reef tank life...

It was a miracle of modern science at one point but far better methods have
been proven.
