## Description

Review: Good value. - I'm using this to filter out fine particles after dosing lanthanum chloride to my reef tank to reduce phosphate. I initially did not use a 10 micron filter hoping my skimmer will be sufficient on getting the bound phosphate out.. That probably was a mistake and probably caused my yellow tang to develop red blotches breathing in that fine particle. =( I've been running this filter last couple days and stopped dosing LC. Hope the tang will recover on its own... it's not getting worse and eating lots so fingers crossed! But yeah, if you are planing on dosing lanthanum chloride, use this!
Review: Not a fit for Waterbox - Product quality is good but not a perfect for Waterbox sump. Doesn't fit in holder snuggly. They are too big for Waterbox 4" .
