One says it's up to you - oh thanks, that helped a bunch.
That would be me. And it's true. You know the pros and cons, so you are the only person who can make the decision. Not trying to be rude, but that is the truth.
Without proper maintence, they can be a hassle. You would need to make sure to perform regular water changes to prevent buildup under the UGF
. Things can sit down there and cause nitrate problems. With regular maintence, including syphoning under the UGF
, you may not have these problems.
If you do proper cleaning on your planted tank, the roots do not need a UGF
to survive. And, heavily rooted plants should not be put with an UGF
, because they can grow below the UGF
and not get the required nutrients from the water. A UGF
is a no in a planted tank, IMHO
, but it can be done if you really wanted a UGF
and with the proper plants.
How often and how DEEP do I clean the gravel without an UGF?
Just as deep as with an undergravel filter, and every two weeks or so. I vaccum all the way down to the bottom.
