Water flow question

I'm in the process of setting up my 55 gal. SW reef tank. I'll be supporting
my LR on a PVC frame.
I'm considering drilling holes in the PVC frame system and connecting an
additional power pump to circulate water from underneath and through the LR
via the PVC support frame system..
Has anyone tried this?
How did you direct the water?
Any advice against this technique?
It sounds good to us. Good water circulation through the LR from underneath
and inside the LR structure will reduce the dead areas from external
(outside the LR) powerhead flow.

We are also considering creating some or all of our substrate from extra LR
by pulverizing and grinding it up then placing it in areas of the tank to
simulate natural reef sand bed accumulation.
Anyone tried this?
What method worked best to convert your rock to sand? (We already have a
sledgehammer :-).

Lastly, How reliable or chemical water treatments for reducing chlorine,
heavy metals, and other impurities from tap water for SW tank use?

Thanx.

Hi Mark

Marc responded to your questions!
I just wanted to add one thing that is often missed and rarely
discussed about water flow.

There is a natural current already existing in an aquaria, if you live
in North America it flows counterclockwise. If you live in Australia
the natural flow is clockwise. As such, one should not try to defeat
mother nature and force the natural flow in the opposite direction.

The larger your aquaria the more pronounced mother nature's hold is!

From what I have read, I really don't think that would be "very" beneficial.
Not when you consider the work involved to grind it up fine enough.

If you have "extra" LR why not put it up for sale?

I am sure several people would be interested, myself included.

As Marc said, RO/DI is really the way to go. You could use the money from
selling your LR to pay for an RO/DI unit... LOL =)

actually this is exactly what GARF does to make their 'grunge and it is very
beneficial.

you have to take into account the quality of the LR that you crush. if its
high quality rock with lots of life, you will have many coralline spores,
pod eggs and all other forms of life that come from the 'grunge' made by
pulverizing LR. IME what GARF has to offer is one of the best "activator"
kits for your sand bed.

What/who is garf?

I am not trying to disagree or start up anything. =0
I respect what you said and I have a question.
I am not familiar with GARF. Will they crush your existing LR for you or do
you have to buy the 'grunge' from them?

~Mort

you buy from them, they take high quality LR with lots of life and many
different colors of coralline algae and grind/crush it up into a 'grunge'
their web site is www.garf.org and you can find more info about it there.
it works great and pod population has always been dramatic with the
introduction of it to any system I have tried.

seas.
