Lanthium chloride. Dose according to bottle and test your ALK.

Yes lanthium chloride works wonders for removing PO4 quickly, just be carerfull

Agent Green is another lanthanum chloride product at Big Al's that I used on my pukani. Seemed to work good.

I too use the phoz down with great results. But be sure not to drop it to fast as i have gotten carried away a couple times after testing and added an extra dose on top of my dosers normal amount and found a random white sps the next day. Just find a dose that steadily yet quickly drops it and keep it pretty steady until you are within range.

there has been some reports of lanthanum chloride affecting Tangs of the genus Zebrasoma. any experience with this ?

plus there are some other inherent problem like removing the resultant flocculent and the potential for deposits on equipment and tank sides, which reportably is very hard to remove from the glass and causes problems with the impellers in pumps.

Again why you would do a slow drip into a filter sock to catch the precipitate

I set him up with foz down, now he's gotta deal with it The number of tangs has been significantly reduced.

Assuming your socks never overflow then wouldn't be a problem , but if it doesn't then precipitate will make it through , I also I should note that it's recommended to use a 10 micron sock while most in our hobby are 200 micron
