Should we use Ocean Water in our Saltwater Aquarium?

You are probably wait for first sings of stress in fish, right ?

For a week you had me considering changing water. My NO3, PO4 and O2 levels
were off. Maybe you were right I thought.

Last week I did a complete maintenance on my system to see if I could lower
the numbers down some or else I was going to GRADUALLY start changing water.

Well, after changing two of the filtering media on my system and adding
another air pump to the system I am glad to share my new numbers on my
website.

After these changes the NO3 came down to 50 (looks between 50 and 75 but is
closer to 50) my NO2 is at 0.1 and my PO4 is lower than 1 (between 0.5 and
1.0 but closer to 1.0)

The point is that I am able to make adjustment to the system in seven
different ways and with my charts its easier to pinpoint what changes should
be made to achieve this.

Well, my fish is doing fine, no signs of stress, the inverts are thriving
and algae is blooming in my sump not in the tank.

I am sure the system works. Not only that, there is a huge accumulation of
Phosphates (PO4) and Nitrogen (NO3) rich debris under the minitank just
before the skimmer. If I am able to remove NO3 and PO4 before the water
goes back to the tank then there is no need to change water.

Thanks for the heads-up, I'll keep you informed!

Ya... keep me informed. Show me how your tank will manage to
drop nitrates below 1mg/l (one!) and phosphates below 0.05mg/l (5/100)
and then we will be interested here with learning about your method.
But then we will also like to know the measurements in between 100mg/
and 1mg/l and what has caused them to drop and how quickly... :-)

Is a promise!
