My phosphates are through the roof, so high the Hana checker couldn't even read how high they were :neutral: Plan on running Rowa this weekend.

Bought a big bottle of Foz Down and my friend calculated that I need to put 720 drops in my tank (600g total volume) a day for a week :eek: Haven't tried it yet, and I also need to get filter socks for when I use it......sigh

You can run filter floss when using foz down. I do and it works great plus it's cheap to do with floss

Anyone else use PO4x4? I've had great results with the stuff

2 weeks ago I had very high phosphates, I listened what everyone said and got a reactor with gfo and now a week later my phosphates are great! Thanks everyone :)

Gfo works immediately, once your notice algae getting more frequent on your glass change the media out...I change mine about once every month and a half :)

Since your system is so large I would recommend the high efficiency gfo, others can use the normal efficiency.

I use the Foz Down myself in my acro system. I used to use HC GFO but it got expensive quick. Foz Down is a very cost effective alternative to GFO. Some people choose to remove it with mechanical filtration but I personally don't worry about it. Into the overflow it goes and bye bye Phosphate.

Shelley I wish there was something like Foz Down for Nitrate but I haven't found it yet. ;-)

Cheers,

I would hope you do... :)

Yep, bye bye PITA GFO reactor.

One other "best thing I did for the system" was get rid of the Ca Reactor. Too finicky and too much maintenance.
