Looking deeper into different media’s | What is bound or released

Zeolites do not bind phosphate from seawater. I doubt they bind much nitrate, but may bind a little. Certain zeolites can bind a small amount of ammonia. I don’t see that as a benefit, but I suppose someone else might.

I don’t think water clarity (a somewhat vague term) is a strong effect of a zeolite.

Folks should be careful to not confuse effects of bacteria growing somewhere that may happen to be on a zeolite with direct effects of the zeolites themselves.

I'm not an expert in zeolite,but zeovit users say it drops nitrate and phosphate. I used them in the past, a few times in a canister filter when I had nitrate issue and I can testimony that it strongly decreases the nitrates in a few days only. But this effect drops after a time which make me thinking that it comes not from bacteria or it would be more slow and increase over the time and not decrease. This seems to correlate with what Kz say and why you should replace them after a few weeks when the effects drop.but how it works no idea.
On reefer had a theory that as it bind ammonium which make that the corals can not any more use properly phosphate and that, so they will use the nitrate which will reduce.

It seems to keep nitrate and phosphate in-check for me (I switch it out every 3-4 months though).

You use zeolites? I didn’t see mention of them in your build thread. Did I miss it?

Nyos Zeo, which is their own form of zeolites.

The zeovit user folks have made some unsupported claims in the past, but since KZ does not say what the material they sell is made from (aside from being a mixture), I'll hold off on further comments about an unknown solid.

I will say that, to my knowledge, KZ does claim it has that effect on its own, but that when used with bacteria and carbon dosing, it does:

"If used together with ZEObak and ZEOstart you can eliminate with the ZEOvit® Nitrate and Phosphate from your tank

ZEOvit® is a balanced mix of different zeolites. It is an absolutely natural Zeolite mix of highest quality.

I don't think my Nyos Zeo consumes all my nitrates - but I think it helps in combination with everything else. I also dose Zero and Bio Booster/BAC (when I can source it).

Yes don't know how it works but it works, but what is strange is that the effect become less after some time ,if it was bacterial only it would not no?
