yeah its leaching from my rock i know that but i need it gone fast so that i can add coral then ill worry about it leaching from my rocks a different dayThe slow step is not the removal of phosphate from the water, but the removal of it from calcium carbonate surfaces, some of which may be deeper down in sand and pores and may keep coming out for an extended period.

another 4 hours later phosphate at 0.41
well i know which of my rock is leaching the phosphate should i take it out?Just pointing out that if you drop it to 0.05 ppm, and wait 24 h, it might pop back up close to where it started.
why?Dont go too fast....rapid changes are not good.
why?
i have nothing in the tankBecause if things are used to numbers being high, and you all of a sudden plummet them it can effect them. You're better off taking it smooth over a number of days then all of a sudden bottoming out your phos in one day.
took the rock that was leaching phosphate out it was from my tank that had 4.0ppm phosphateJust pointing out that if you drop it to 0.05 ppm, and wait 24 h, it might pop back up close to where it started.
You want it to be gradual, not fast especially allowing you to monitor level. Too fast and you can end up at Zero and then acquire dinoso my phosphates are 0.6 i want them like 0.05 i don't have anything in the tank so no need to take it slow
i have overdosed the phosguard how fast could i possibly get from 0.6 to 0.05
well i know which of my rock is leaching the phosphate should i take it out?
Is there a reason to think Fe release from GFO or Al release from phosguard is better or worse side effect than the other?
yeahIs there sand present?
Correct me if I’m wrong. I’m under the assumption that iron doesn’t tend to accumulate because many organisms that we keep can readily consume and require iron. Randy even recommends dosing iron in tanks housing macroalgae.Is there a reason to think Fe release from GFO or Al release from phosguard is better or worse side effect than the other?
True.the dsr method doses lots of iron to bind phosphate, and Red Sea recommends a very high iron level.
yep, organisms like it, and also saltwater kinda holds Fe poorly.Correct me if I’m wrong. I’m under the assumption that iron doesn’t tend to accumulate because many organisms that we keep can readily consume and require iron. Randy even recommends dosing iron in tanks housing macroalgae.
Most of the data have a negative correlation between aluminum and organisms.
yeah
maybe but i am hopeful it was just that 1 rock that was only in like 1 or 2 weeks on another note my phosphate is from 0.6 to 0.21 in 24 hours i love phosguard and would recommend it to any 1The high surface area of the sand may be holding more than the rocks in your tank.
