You need to distinguish "fish-only" sal****er tanks, from reef tanks that
include corals. (Especially since you've posted this to r.a.marine.reefs,
a newsgroup specializing in reef tanks.)

Are you really recommending that 70mg/l for prolonged periods will be fine
in a reef tank? That, in your opinion, corals will show no drastic effects,
along with fish?

If that's what you mean, then you need to back it up. If it isn't what you
mean, then you've written very poorly. Or else your post is completely off
topic in this newsgroup.

He does not really know what a reef tank is.
He has never owned one in his life.
The single tank he has oned was a fish only tank with 7 fish.

This argument was used against him long time ago and
then he added Xenia to his tank to "make it a reef tank".
The future health of this Xenia coral is knot known, but
in 100mg/l nitrates and standard fluorescent bulbs its fate
was quite easy to predict to all of us discussing with Jaime...

I do not encourage water changes.

Why? Do you have anything to offer here except your random opinion?

He has his own tank, with magical filter which he wanted to patent :-)

This measure is needed but for other reasons and should be kept to a
minimum.

You don't encourage it, but yet it is needed anyway?
Why is it needed? Why don't you encourage it?

When I asked him similar questions long time ago he
concluded that I want to know too much about his filter
he wants to patent and I should not ask too many question.

Ø When doing water changes, keep it to small amounts (10%)

Please justify.

10% every six months? In a reef tank? Really?
How well are your corals growing?

Jaime, would you care to post some picture with close ups
on your corals? :-)))

If you have to do water changes more than once every six months (some even
weekly): you can toss all your gadgets away because they are not working.

Again, are you able to rapidly grow stony corals with only a 10% water change
every six months? I'd love to do that. Please describe your entire system.
Such small and few water changes don't seem to work for anyone else trying to
grow corals. What's your secret?

He cannot tell you :-) He will "soon" patent his filter and then we will know ;-)
