phosban soaking up 2part

[duBduB]

Hey guys, i had an issue last summer running phosban in a reactor and dosing 2part. All was well with my 120 gal and sps reef until i had removed the 2 reactors which had phosban in it. I wondered what had caused the flux in alkalinity when i had removed the phosban. And hearing from many other people, phosban really screws up the dosing by sucking up the 2 part and when removed screws up the parameters.

Has anybody found this to be correct? My tank crashed after removing the 2 reactors of phosban and i will nolonger use it.

This is a known issue with phosban. When starting it out you don't use the full recommended dose. You start with about half and work your way up monitoring the tank parameters. If you are using an exorbitant amount such as 2 reactors on a 120 it will continue to be a problem. 1 reactor on a 120 is plenty sufficient. I run a single reactor on my system of 275 gallons. Overkill such as what you were running will cause issues when you suddenly discontinue it as well.

could you use 2 different materials such a phosban and purigen (seperated by a sponge or something?) in order to moderate these effects?

I had an alk problem when I started using it but it has been fine since. I just have to watch my levels when I change the Rowaphos.
