I use poly filter floss as needed. It offers an added level of filtration, particularly when trying to filter out fine particles from the water column for polishing the water.
its a 4 stage spectrapure unit!

I think the bigger issue is the high aluminum level in your water, not the use of filter floss.
How is your tank? I'm guessing something called your attention to the high aluminum levels.
Are these levels before or after the RODI?

I would probaly just use the 8x4" piece of polyfilter as it is and see how you go with that...you cant overdose it...i swear by it myself and use it 24/7 rather than even using a skimmer
A lot of people don't even know what the product polyfilter actually is and what it does and think you are talking about polyfill/filter floss etc

I'm not sure polyfilter alone will do the trick (honestly don't know if it can remove metals or not). You might want to slightly increase your water change frequency in addition to using the poly.
As for how much poly, I'd say start with 3/4 to 1 inch thick. Really depends on the flow through your overflow. If you see the water level in your return pump chamber start to drop, you'll know it's either too thick ... or too dense ... and water can't pass through it fast enough.
BTW - if you're trying to track down the source, it's my understanding that some ceramic frag plugs may contain Al. If you do a lot of fragging, there's a slight possibility that could be the source.

Fair point. I would be one of those people. I thought he was speaking of filter floss. What is polyfilter?
And again, I think the bigger issue here is what has been going on with the tank that has called attention to the presence of aluminum in the water?

There really is no set amount based on tank size..
You want 2” thick covering entire are medium pack. Anything more and you’ll reduce flow too much and only the top inch or two really ever gets dirty so no need to go overboard. Pull and replace every few days or weekly.
(Medium pack) wet soak the poly so it isn’t so fluffy then loosely fill.. not packing it tight.
Again different stuff... polyfilter and filter floss are totaly different products

It bears repeating that polyfilter is not filter floss and not just a bag full of pillow stuffing that needs to be soaked and packed down. This is a chemically designed filter pad to remove contaminants, metals and medications. Why do people dispense advice without reading the OPs information first?
Put the polyfilter somewhere with high flow and preferably where all or most of the flow has no choice but to pass through the poly pad. If your sump has a flow-over style bubble trap before the filter socks, laying it down right on top of the socks would be perfect.
Cut it to size if it's too big. When it changes colour to bright red (the polyfilter colour change for aluminium) then change it out. It may only take a day the first time, hopefully longer the second time. Repeat until it doesn't change colour anymore.
It might be worth increasing your testing for a while to monitor everything else to keep things stable.

My bad I missed that part.. OP was talking about Polly filter pad.. my new question is why is the OP needing something to remove ammonia? There is bigger issue not going to be solved by magic products. First he should be addressing the cause of the ammonia itself.

**aluminium. Not ammonia.
Personally after using all 3 i found the only filtration required was polyfilter to keep the water sweet....it is possible to overdo filtration and starve corals
Works well for me just 10% weekly water changes and Polyfilter changed every two weeks
And no skimmer either

My personal take on them is this:
They all do what they say they'll do, the question is, do you need what they will do for you?
Purigen is redundant in the presence of sufficient amounts of live rock. In a newer system, you're just messing with the tanks ability to mature normally to get to that coveted 'stability' many months down the road.
Chemi-pure has it's uses, but my preference is regular activated carbon and/or GFO when my testing shows I need it.
Poly-filter is great when you suspect a contaminant it can remove, and need it out quickly. It removes several things, including iron, a necessary trace element for corals and macro algaes. It removes ammonia, which is good if you have an ammonia problem - but then you won't know you have a problem. It's also quite efficient at removing copper, which, in very minute (and mostly untestable) amounts, is also a necessary element. Unless you need to use it, I don't see any benefit.
