Marc Weiss Phosphate Magnet

[Waterbury Guy]

Looking for some help with this product. I have a hair algae problem (use RO H2O so not sure where the phosphates are from) and it was reccomended by my LFS to use this product. My questions is, I do not have a sump or filter to place the poly bag in. Would it be OK to put it directly in my tank if front of a powerhead? Also the product states "mix with activated carbon to avoid arsenic contamination". Well, since I don't ahve a filter, I don't use carbon. Could I put some in the poly bag with the Phosphate Magnet? Any help is as always appreciated.

PS.
Any opinions on his Coral Vital product?

Not sure about the product but have you checked for silicates and phosphates since you dont use a di on your ro?

Hmmmmm seems like the very first time I posted it was regarding MW stuff, seems like a worthwhile topic for 9000.
Not familiar with the PHOS MAG but the caution to mix it with activated carbon to prevent ARSENIC contamination!!!!!!!!!!
That can't be good, and certainly not something I would try in my tank
When I first started my 29 reef I bought several bottles of his then most popular products, ei Coral Vital, LR activeator , etc I didnt have amazing growth and results , I got a messy , algae overgrown tank and that was a nitemare to fix
So bottom line based on my personal experience and reading the opinions of alot of reefers over the years I would spend the $ elsewhere and address the real problem, FWIW

If it were me, I would spend the money and get an "add on" DI cartridge for your RO filter. I believe that this is where the most phosphates and silicates are removed.

But, I have also heard that Marc Weiss', Phosphate and Silicate Magnet product, is the ONE product of his that has any value. People have reported good results with THIS product (compared to his half fermented, apple cider and other various forms of sugar) Coral "Vital" and Reef DNA. I have used both these products before with only algae outbreaks like Doug's experience.

I believe the P&SM product is ferris oxide. You should purchase a small canister filter to put the product in. One that hangs on or one that could go under your stand. If you got a big enough one, you could stack the P&SM product on top of a bag of carbon.

Thanks everyone! His statement about arsenic contamination scares me a bit. Now looking at Kent's Phosphate Sponge. Instead of purchasing a canister filter, could I put the sponge in the recomended micron bag in my Remora Pro where the water feeds back into the aquarium?

[Doug1]

Yau could if theres room and it doesnt impede skimmer function.
BTW the Kent sponge is prolly Alum oxide based, soft corals esp react poorly to it

I've heard only poor things about Mark Weiss products. Besides...I never add anything to a tank that doesn't list INGREDIENTS!

[Waterbury Guy]

Thanks for the tips. As I only have softies this would be a problem. Now I'm on to researching Rowaphos. Any positive/negitive comments?

Darn there was a product out a few years back, I forget the name but it looks kinda like a brick red scratch pad almost
My friend had tried it at the LFS and it seemed to lower PO4 AND NOT p*ss off the soft corals

i have seen this, some sort of polyfilter...i think.... i think..... hmmm...

[cyberchef]

There is a poly mat that will absorb phosphates, metals, and a slew of other things, great for a quick "I need to help this tank NOW" type of thing. You can just float it in your sump or place it so the water flows across/through it while running thru the sump.
