Water parameter

[blueclown]

Hi all,

Corals not doing well in my tank, so quickly perform water check this afternoon.

Here's the finding:

1) Salinity - 1.023

2) Nitrite - 0

3) Nitrate - 0

4) Ammonia - 0.25

5) KH - 9

6) Phosphate - 1.0

7) Ca > 520 (beyond the max indicated by the API test chart)

8) PH - 7.4

Calsium is very high, PH at the lower range.

Need advice from bro/ sis, how to reduce the Ca and increase PH.

Thank you.

Measure your new salt mix water parameters with same salinity as your main tank. PH, KH, Ca

Cheers,

James

For Ca either change water or let it reduce by itself thats the only choice u got.

As for PH, read this article. the solutions are given at the end: http://reefkeeping.com/issues/2004-09/rhf/index.php

I have doubt on your kH level cos I am having a high Calcium situation now and I need to dose alot of sodium bicarbonate just to keep up with 8dkh.

Cheers,

James

check your mg levels

It's best that you do atleast a 50% water change if not most of your coral is not going to survive. There is a build up of something in the tank also hence your ammonia level. How long you have this tank and the size ?

When you fish for love, bait with your heart, not your brain...

I would think that ammonia should be '0' - need for more life rocks. Phosphate or nitrate got digit gotta WC (water change). That's the traditional way. Bio-tech way is to fix a ats, no wc.

Sodium bi dose until u get 8.2-8.4.

Cal stop dosing for the moment.

Test your magnesium.

Your NH4 is high, Should be 0. Your test kit have problem and what is your MG reading.

Hi all, Many thanks for your advice. So far few LPS can not make it, luckily not much corals inside my tank. No issue on the fishes at this point of time, still eating greedy. Do a major water change today, approximately 50% as suggested. Will try to get new test kit to measure the water parameter again. Thinking to buy Hanna Checker due to the accuracy, may i know which shop selling it.. Thank you.

Dont forget about light and water flow too. Water parameters are just one part of the equation ah

Salifert test kit is good enough, bro
