Aquascape! change?

[Roberto CRC]

Hi friends,

I have in mind to change the aquascape of my fish tank, this in order to improve the flow of water in the display.

My tank currently has more than a year and a half.

The idea is the following:

1- Of the 100% of the stones of the system, approximately 70% is in the display and the remaining 30% is in the sump. Sump stones not going to change nor the sand.

2- 70% of the display, it would change everything for new and dead stones.

3- Changes that 70% of them in 3 equal parts, with one week of difference between each change.

4- The amount of new stone to intruducir would be less than that currently there, I estimate that 25% less.

So my questions are:

How much I can affect the stability of the system?

Make changes every week, is very little time?

A peak can occur ammonium, nitrite, nitrate, phosphate?

Regards.

How big is your tank and how many fish? List the fish out if you can.

Total (Sump + Display) are 150 gallons.

Fishes:
1 Blue tang
1 Purple Tang
1 Yellow Tang
1 Fox Face
2 Black Ocellaris
1 Cardinal Bangay

I have corals, soft, LPS and SPS.

I feed between 3 to 4 times per day as follows:

In the morning, nori
At noon: Pellets
At night: Alga Nori
and every 2 days at night feed with flakes.

Due to your bio-load (tangs/foxface are pooping machines) and feeding regimen, I would change out your rocks very slowly. Take a couple of months to get it all done. Otherwise you risk a mini-cycle (ammonia spike).

I understand, pity that last as to avoid exe process and ammonia spike.

You can minimize the pooping by not feed your tangs for 3-4 days before you change your rocks and 3-4 days afterwards. They can go a week without eating just fine.

Many of the fish stores don't feed their fish for several days before shipping for the exact same reason.

You can also add those black sponges to build up bacteria a few weeks before you do the rock changes.

With this, you can speed up the process. Besides you are only change about 25% of the total rock at any time. I don't really see a big issue.

Thanks, black sponges would place them somewhere to fill with bacteria? or for what purpose?

It fills with bacteria so that the bacteria population can be quickly established when the new tank is set up.
