Dry Rock and Phosphates

fernalfer · 03/03/2016, 05:12 PM

Ok i just filled my 120 gallon up with tap water and vinegar to clean it and to leak test the tank. Question is can i throw my Marco Dry Rock in there as well with a powerhead? Will this alone help rid the rocks of any phosphates or is doing this just a waste of time?

After doing this was going to rinse the rocks real good let them sit in the sun and then make up some RODI saltwater in a 45 gallon Brute tub and stick the rock in there to cure with a heater and powerhead. With weekly water changes.

why not just cycle the tank with the rock's. you're not running LR why cure? run some high cap GFO and forget about it.

I would not soak it in tap water, the rock is likely to absorb some of the pollutants in the tap water, you want to start as pure as possible.

just throw them in the tank and get your system cycled.
my measured phosphates haven't increased since the day i started. i think a little too much is made of them on RC and it gets people worked up. if they become measurable in your case start with a gfo.

I would cure the rocks in a separate container and dose the container with lanthanum chloride to rid the rock of phosphate. Hi capacity GFO will work but lanthanum is way cheaper and who knows how much phos is inside the rock. Lanthanum will do it right.

This is perfect for lanthanum dosing dry rock. http://www.amazon.com/Blue-Life-USA-...hanum+chloride

I'm 14 months into the life of my dry rock and I have experienced no phosphate leaching. I just put it in, cycled, and off I went. Couldn't be happier with it.

Good luck you should be fine with your rock in there. Treat it like others said if you are worried.

So i have had my rock sitting in tap water and vinegar in my 120 gallon now for about 5 days with a power head circulating the water. The first 3 days the water was clear. Now the water is very cloudy hard to see in the tank. Is this stuff all coming from my Marco Rock?
