- - NEW Tank Build !!! (http://www.canreef.com/vbulletin/showthread.php?t=95033)

So a while back as you know I was suffering from a curious tank crash, I blamed the Dry rock others blamed me for being hasty!

First I will admit a real dumb ass error how I did this I do not know blame it on life stresses but I have to be open otherwise this will make no sense. I reported before the crash my Phosphate was zero, well on the Hanna meter it was! Well 3 weeks ago I realized I was not using the correct reagent! So once I corrected this dumb ass error I had a PO4 of 70++++ tank crash reason found! So now I have new rock in the tank and low and behold the surviving corals came round in 3 days I started testing the Dry Rock which was now in PO4 free RO water mixed to NSW levels at 28 degrees and well circulated.

The water started at zero PO4. Today it is reading 25ppm PO4 and thats after a 75% water change only today.

I think we can conclude the rock i received to be leeching PO4 and the reason for the crash.

Do yourselves a big favour, before adding any dry rock, leave it in a vat of PO4 NSW and after 3 days test the PO4 level. It may just surprise you.

PO4 has been brought down by Ocean Fresh Phoz Down! Now all dry rock is out including the pieces in the sump the PO4 is stable and around .05 and coming down.

It might be 25ppb PO4 ;P

And I am just too impatient to use dry rocks (maybe that's I don't like it?) and adding another lengthy step to setting up a tank.

I do see the rock leaching. As I read about Marco rock which is what I choose to use. I kept rock in holding tank and did water changes from the water in display tank. Also used prodibio. After two months I used it to set up new tank and tested today no po4

Down fall is the lack of biological on rock and I am seeing the coral react to the Marco. It'll take time but in long run I'm sure ill be happy with the Marco

I think your analysis is spot on ;)

looking good in there sir.
