Two Little Fishes
 

Hi,
I just purchased the Two LIttle Fishes phosban reactor (algae problems) and some RowPhos. Do you fil the reactor with the RowPhos or how much is needed?

250ml is an average fill.

What size is your tank? About a cup is average but you can use less or more depending on the size of your tank.

When you read the instructions in the rowa container it specifies how much to use to water vol,read closely because I believe the amounts differ if you are fluidizing the media(putting in reactor). More is not better when you are just staring to use po4 removal media. If you add too much when staring you'll pull the po4 out and the bacteria feeding on the po4 dies, decays,= bloom. Always start slowly when using these types of products.
