"Foz Down" by oceanfreshaquarium.com

[Delphinus]

Unfortunately they don't seem to list info on their website yet but fwiw their website page is at http://www.oceanfreshaquarium.com/

The bottle label looks *remarkably* like another of their products, Cyano-Starver which you can currently pick up at Red Coral in Calgary. I don't know if it's the same product but been renamed or if it's something totally different. I'll see what I can find out about that.

product called cyano starver does the same thing and worked for me as well

Great to see the product has found its way onto Canreef, we start exclusive distributing it nationwide as of next week.

To answer some questions that may come up

Foz down is a floculant binding agent, its binds the PO4 in the water so it can be skimmed out or caught in filter socks.

If you have high PO$ it will turn your water a wee bit cloudy for about an hour, this is the physical action of the PO4 being bound.

The results are instant, test your water 1 hour later and your PO4 will be remarkably down.

It will take probably no more than two dose split by 48 hours to rid a tank of a low range PO4 reading. Do not over dose and crash the system fast this is not good for your tanks inhabitants.

You can do a maintenance dose every 48 hours, I do, my corals have got colour I have never seen before!

If you have high nitrates it is advised to keep a low level of PO4 until the nitrates are down as carbon source dosing needs a level of PO4 to work.

I have calculated that 1ml a week dosed through a dosing pump will keep your PO4 at zero, this dosing is based on a 100 gallon system, any lower volume than this auto dosing is not possible.

If you have any questions please let me know.

the product was originally labeled cyano starver, but since the effect of the product is not limited to cyano, the name was change

Is it lanthanum chloride?

Edit: Didn't see that this was asked in the other thread nevermind.

I've been using it for a few weeks now and it works well. I'm impressed. I used it to get down low and then use rowaphos to maintain a low level.

what "other thread"? And is it lanthanum chloride? Sure sounds like it could be.

I asked Aqua-Digital if the product is Lanthanum chloride in his advertising thread. Not surprisingly, the ingredients are not disclosed.

If it is indeeed Lanthanum, it will not be skimmed out, it has to be mechanically filtered out. It seems as though getting 100% of it out of a display tank setting is not possible and some people (including Randy Holmes-Farley) question what this precipitate will do over time if left in a tank. Personally, I wouldn't want to be dosing a Lanthanum-based product into a tank, but I would definitely use a Lanthanum-based product for curing base rock or high PO4 live rock. Be aware also that if more Lanthanum chloride is dosed than there is PO4 for it to bind to, then it will bind to CO3 and precipitate out which will deplete alkalinity. For the reasons listed here, I wish manufacturers would list ingredients so we can judge how best to use products instead of relying on manufacturers suggestions which are all too often not the best idea. Like say a Remora Pro skimmer on a 125 gallon tank?

I wanted to learn a little more about this company so I went to the website and was pleasantly surprised to learn that it is a subsidiary of Seacare, an enterprise run by Tim Tessier. While I doubt Tim remembers me, Tim and I have conversed a few times over the years especially in the 90's when seacare.org was THE go-to vendor for Tridacnid clams in Canada. That was a long time ago though, over time the business switched to a wholesale operation only, and us mere mortals could no longer buy from him except vicariously through other retailers.

Tony, I bought my first Radium bulb from Tim - Nice Guy.

Thanks Tim for jumping in here and clarifying that. I think that knowing that you use this product yourself on your own systems, and for such long term periods as well speaks volumes on your own confidence in this product. Also thank you for the clarifying the difference between Cyano-Starver and Foz-Down.

As to the difference between whether the inertified (I maded that word up myself just now, woot woot!) phosphate is skimmed or settles out, I think back a few years where it was accepted convention to dose kalkwasser for that it would also bind to phosphate molecules that then settled out on the substrate and sand. I would imagine that this is probably pretty similar. One should probably budget to replace sand every few years as matter of best practises - besides, there are not too many tanks that last longer than 5 years anyhow.
