This is my question this morning

[jsker]

This is my question this morning my No3 Po4's have been running high for the past two months. I have a 72g tank and I have been making 20% water changes every two to three day for the past month. My tank is 9 months old. I am using Red Sea Pro and my Corals look the best they have ever have. I had a lot of grayish algae on the 1 inch sand bead and my 75+ pounds of live rock. I also have some hair algae growing on the top part of the live rock still but the gray stuff is pretty much gone. I have been trying to run a simple live rock and skimmer system. I just had my Kole tang kick it in the last day.

Im sorry, what was the question??

How long have you been dosing and how much NOPOX?

What is NOPOX?

 

[zzzdiver]

Red Sea brand carbon dosing

Im sorry, what was the question??

What am I doing wrong, am I changing out to much water and stressing the fish out?

 

[jsker]

How long have you been dosing and how much NOPOX?

About a month and a half

 

[jsker]

What is NOPOX?

Red Sea brand carbon dosing

it is a Red Sea product for lowing your No3 and Po4

 

[zzzdiver]

Imo that is an lot of water changing. I believe your doing this in hopes of lowing the PO4.
If so let the NOPOX do its job, your algae has been dying off. I switched from zeo system to the Red Sea 8-9 months ago and it took time to see the result. How much NOPOX do you dose?

 

[Reefing Madness]

Whats the TDS coming out of your RO/DI ??

6ml for about 50 gals of water

like .001
I think I stress the fish and the now have velvet

 

[Reefing Madness]

But the velvet had to come from somewhere, it just doesn't appear out of nowhere.

Same fish since March, except a file fish in June. Other that that just corals

FWIW, water changes are typically not very effective at reducing phosphate because so much can be temporarily bound to rock and sand. SO a 100% change does not get rid of it. Water changes are fine for nitrate. 0.9 ppm nitrate is not a problem unless you have problem algae. How bad is the algae? I can't really tell from the picture. The phosphate certainly is high.

The Algae was pretty bad, but under control now. I started to run a GFO (Rowa) again Sunday and still dose with NO3Po4X

At least you know I keep up with my tank maintenance

It is there, One of my clowns passed in the night.

From what I have been reading, I could have stressed the fish with so many water changes trying to get the Po4 and No3 under control that I have weekend the immune systems of the fish and the velvet or what ever it is has been in the tank all along. it looks like I will lose one more clown and the other two fish left are eating the medicated food. Those two should live. the odd thing is that the hippo tank looked like she was not well 2 weeks ago, but she is fine now and eating the medicated food.
