Phosban-L is a new liquid phosphate reducer from Two Little Fishies using the tried and tested Lanthanum Chloride additive. Phosphate is just about public enemy number one when it comes to having a clean and healthy reef tank with minimal algae growth.
Two Little Fishies pioneered the use of granular ferric oxide (GFO) with phosban and this is still one of the most effective ways to reduce phosphates on average home tanks. But if you have a very large tank or exceptionally high phosphate input, GFO can get really expensive real fast.
Dosing Lanthanum to aquarium water is much more economical and can actually be more easily automated since you can use a programmable doser for regular additions. The only drawback is that LaCl can really only bring down phosphates to around 0.1 ppm while GFO will scavenge all available PO4 down to near undetectable levels.
Two Little Fishies is making Phospban-L in two sizes as a liquid, a 500ml and one gallon size, as well as a concentrated powder form that you can dissolve and dilute yourself.
