Hi Brett,

Adding the Foz Down the way you suggested is a good way to use it.

As for effectiveness it will immediately bind with any Phosphate it comes in contact with. If you have a lot of Phosphate it might plug the filter sock quickly.

If you have a bucket for ATO water it could be added to that. Then a dilute amount will be added continuously during the day. The water outlet hose for the ATO could be run into the back of the overflow or even directly into the filter sock. I have heard of aquariums using sand filters so a 200 micron filter sock should work well.

I'm sold on Foz Down, just have to wait to get some. *Ahem* Tim......

Haha!

They should be ready end of next week.

Is it important to add foz down where you can catch the precipitate? Is it a must do to remove whatever forms?

I have to chime in here
I have been having a huge algae issue for a long time in my 250 gallon system . I am doing 15% water changes weekly and have reduced feeding and am still fighting this battle. I tried FOZ down to the tune of 2 -8oz bottles in 2.5 months and had no change that I could notice. I actually put in 20ml 3 times in 1 day and measured phosphate before and after each dose and the following morning with no measurable change.

It may work for you but just beware it is no miracle cure....and the battle continues

GFO is doing a good job for me I'm just looking at ways to minimize maintenance. One less media to replace every 2 weeks would be nice. As soon as I exhaust the 30 lbs of HC GFO I just bought I'm going to take the stuff for a test drive.

Since upgrading my lights algae has become an issue...my refugium can no longer keep up so I have begin today to use Rowaphos. Time will tell.

I put some dried live rock that was given to me into my 50 gal when I started it. When I bought my po4 testkit 3 weeks later I was at 5ppm. I started doing 20 percent wc twice a week and quickly got it down to .9 ppm. Gfo diddnt do much for me. Algea scrubber built from anaquaclear 500 helped alot.foz down brought it down very fast. Tank looked like a snow globe. That was about six weeks ago. Now phosphate leaches from the rocks at about .1ppm every couple of days. Foz down will drop it to zero in an hour. Hair algea is dying and phosphate is leaching less and less.

Wow, 30lbs is going to last you quite a while :biggrin: I am trying the new HC GFO at the moment. Do you find your skimmate is quite dark now? Some have suggested I may have it tumbling to much but I have it moving very gently. How are you liking it :question:

Yeah, as I said. I don't want opinions on my maintenance, just on products out there people are using....but thanks.
