LaCl source? Cycling new rock and am interested in using it

[Holy_makerel]

Just like the title says. I've got rock in RODI soaking for my new build. I want to use LaCl to remove phosphates. My interweb searches for it brings up a bunch of products and I'd like to know what others have used and recommend. Plus how do you dose it?

Thank you!

Brightwell makes Phosphat-E.

I've used a pool chemical, as have many others, called SeaKlear. I used the commercial variant, which is just more concentrated.

Dosing it when curing rock without livestock is pretty simple. Just pour a spoonful into the water and it will bind with mainly phosphate, though it also reduces alkalinity. Repeat the process every few days to a week until testing shows no more PO4 leaching from the rock. You'll just have to thoroughly rinse the precipitate off of the rock before moving it to the display because the precipitate can irritate the gills of some fish.

To dose into a running system, you should dose it into some sort of filter fine enough to capture the fines. I think 5 micron is the recommended size, but I used a 1 micron filter sock. I teed off of my return line to have basically a water fountain rate of tank water going into the sock. I diluted a couple ml of SeaKlear into a couple gallons of RODI and dripped it into the sock over about a day.

Thank you for the response!

I looked at the seaklear but wasn't sure if it had some additive that might harm inverts/fish later on since it was for pool use.

Looking forward to getting this rock ready for the display.

Some seaklear is pure and others have additives. It can be hard from the Amazon listing to see if you're getting the right one. I sadly ordered the wrong one and wasted $$$. Ordered Brightwell after that.

Hmmmmm. Thanks for the heads up.

Iv had luck in the past with PhosphateRx from Blue Life.

I suspect PhosphateRx is quite a bit more concentrated than Brightwell. Not better or worse, just I think there is a big difference. Like a drop from one is equal to a milliliter from the other
