Will Kent Nitrate Sponge remove phosphate also?

I was wondering if Kent Nitrate Sponge will remove phosphates as well? What about Kent Absorption Resin or Kent Mixed Bed Resin? Does anyone know what these actually remove from the water? Are they safe to use in a Phosban Reactor?
 
The best choice of a material by far for binding phosphate is GFO (granular ferric oxide). All such media are red to brown/black materials. Other materials potentially leach aluminum or do a poorer job of binding phosphate. I do not believe any commercial organic polymer resins will remove much inorganic phosphate from seawater.
 
I was asking because it was alot cheaper then GFO. I could get 1 gallon (3,764 grams) of Kent Phosphate Sponge for $30 on ebay compared to the GFO (453 grams) at bulkreefsupply.com. That's more then eight times the amount.

Does anyone know where to gets GFO at a good price?

I believe Kent Phosphate Sponge needs to be replaced every few days. One way or another, PO4 will continuously find its way into your system and IMO, a quick "one-shot" removal is useless.

Yeah I decided to go for the GFO from bulkreefsupply.com instead.
 
So the only way to remove nitrates would be to use a product that is made for it, which still sucks at it, or water changes which is probably the best choice.

I was listening to an episode of petfishtalk.com earlier and they said that amquel plus removes nitrate. I forgot which part. It was probably part 4.
 
I don't like using chemicals for nitrates, better to fix the problem.

no one seems to know what amquel is, but I suspect it's a carbon source, sugar would be cheaper, but not for the faint of heart. I think skimming and reduced feeding are the best ways to eliminate nitrates. DSB's and RDSBs would be my next choice, if none of these work, there are other methods, including de-nitrators, and carbon sources, but if you have to ask about these, I don't recommend them...

What about plenums, are they any good?

I'm getting some LR tomorrow and I would like to make changes to my 3-1/2 month old 29g FO tank before I start to add the rock. Maybe I should start a tank log somewhere so that I can get better responses for these questions. Where's the best place to do this, the "New to Hobby" forum? I have alot of questions regrading flow and filtration. I started a flow suggestion thread in that forum but barely got any good responses.

Btw, I ordered a lb of gfo from bulkreefsupplies.com today. How often should it be changed?
 
Sand beds can help reduce nitrate. Whether a plenum actually improves on ordinary sand beds has not been demonstrated. It may in some circumstances and not in others, depending on the sand beds involved, and the tank water flow.

I agree. But lets say I'm working on and have fixed the problem (hopefully). Is it a good idea to run a few cycles of the Kent Phosphate Sponge to get my system back on track - together with fixing the problem?

(sorry to hijack this, but it seems like the thread stopped a few days ago)

Maybe if you have some lying around, otherwise I still think GFO would be cheaper, even for this purpose. Also, it's not entirely clear to me exactly what KPS is made/composed of. GFO is just more extensively tested and proven in vivo.
 
It is white, but they don't admit that, if true.

Their only comment is:
"This product will not release soluble aluminum compounds into your aquarium, causing negative reactions from your inverts, as competing products may."

FWIW :lol:
 
Hmmmm. Well I just bought it the other day when I saw it on sale in the store. Now, today, I've been getting caught up on the latest and what I really should be doing. I've been making alot of changes (skimmer, water changes, bioload) to address the algae problem I have. So I'll try this stuff out and see what kind of impact it has.

If it looks like its helping, maybe I'll get some of the GFO to really battle it.

This is really great info. Thanks!

?

I ended up getting some GFO instead from bulkreefsupply.com. I've heard nothing but good thing from it.
