    I switched out tanks about 3 weeks ago, never had problems with phosphate in the past. Changed 2 things when I went to the biocube. Now using ro water and a sandbed. So Im thinking the sand is leaching out phosphate. How do I get it back down. Water changes dont seem to be doing the job. I put phosban in and doesnt seem to work that good. thanks

    How are you using the phosban? Do you have a phosban reactor? Also, old food will bring phosphates up, just check how long you've had your food around.

    just a media bag. Food is only about a month old, I use rods. My 120 is still set up use the same food on that and phosphate is at 0 I really think its the sand. I used 20lbs of the black sand you get from petsmart along with a 1lbs bag of white sand cant remember what kind it was. the bag looked old though.

    If it's silicate based sand, that might be the problem, or the tank isn't cycled yet and you're algae spiking (I've seen all colors during cycling of both my tanks)

    i think you should go get some of daves water and try to do a 50% water change with it. i need to bring your buckets back first though :)

    You mentioned having added sand. What kind of sand was it that you added?

    found the source. My water ph is high so before I put it in the tank, I was adding a half tablet of tank buddies 7.0 that brought the ph down to 8.2-8.4 tested the water after adding one and raised the phosphate to 10 from 0 in a five gallon bucket. What can I add to bring ph down without spiking phosphate. thanks

    Thanks that works great, and didnt even have to spend money. Also had big phosphate drop with a 5g water change, and I think the phosban worked to because it was also down a little from 2 days ago when I checked.
