Just curious, but why are doing so many water changes?

They are my wife's tanks but she kept killing the coral. So i started
checking the nitrates daily. The nitrates would go to 40 ppm every couple
of days. So I slowed down the feeding by 1/2 but it's still is getting
dirty too fast. Everything is healthy now but it's costing me a small
fortune in salt. I use RO water and it has been tested.

Any suggestions are welcome.


This guy is a member of this newsgroup and often has TONS of info, here's
one of his Nitrate article.. its very useful
http://www.melevsreef.com/reducing_nitrates.html

Also, how much water are you changing each time you do your partials?

Good luck

Thanks for the article. Sounds like I need a sump. We put our large reef
tank in a place that can't handle a sump but with some carpentry work I
might be able to put one in.

When I change water I do about 33%. When the nitrates were real high I was
doing 60 to 70% and it didn't seem to effect the fish or coral.

The 45 gal tank has a Eheim 2213 canister and a Remora Aqua C hang on
skimmer. The 29 gal tank has a false back with the filter system -: bio
balls, Sapphire skimmer, filter media, activated charcoal.

I noticed he said that Bio Balls cause nitrates! Yikes. I put bio balls in
the media chamber of the Aqua C. and they are in the false back too. I
wonder if I should find something else?
