Pet Forum / Aquaria / Marine Reef / June 2004

Cyanobacteria allways grows when the tank
lost the stability, some sudden change happen.
In your case, it could be sudden phosphates drop.
In my case, cyano attacks when I do too big water
change to dilute nitrates too much (like 40-50%).

Maybe you overdosed this phosphate removal
filters and the environment change was to drastic?

Yeh I use it,
it drastically reduced the phosphate in my 50Gal, well to a reading of zero
actually,
They say it will remove silicates after a while too,
I'm happy with the product.

I use it.  It has worked very well for me.

I didn't experience this at all.  As recommended in the instructions, I
made sure there was filter material all around the stuff.  I use it in a
Eheim AquaBall filter.  This filter came with a little cartridge with a
finel filter in it.  I took that out and put the ROWAphos in that
cartridge, left the aquaball prefilter in place, and put another small
filter pad after the ROWAphos.  The instructions said to make sure none
of it could enter the tank and it seems this did the trick for me.  I
have to clean these filters a lot, but generally clean them in the main
tank so that the critters can eat whatever is in them.  (I run the
AquaBall in my sump.)

Perhaps as someone else suggested, your tank has changed too fast?  I
started using it before my phosphates were too high, just noticed they
were starting to rise and decided to do something about it.

I use it in my hangon CPR refugium.  It turns solid after awhile.  I'm using
it passively with low flow rate.  45 gallons an hour.  My tank looks
healthy.
