Good water quality, is it more than the common parameters?

Copied this from another forum,(I hope the poster dosent mind), another valid theory.

If that's the case then pollen would be ruled out.
The recent, sharp, increase in ambient temperatures (15c in three weeks) and their fall during autumn would suggest it's related to the tanks metabolism.

Don't you have heaters and chillers to maintain tank temps over there?

Haha yes we do. I think we have gotten to the point where temperature is actually something we can control in the UK. Although to be fair I can't speak for everyone!!

It is interesting that the end of summer/autumn is also mentioned, as this coincides with the release of another pollon in the UK. Here is an extract from the governments pollon count website

Pollen season

The pollen count season is normally March to August. However, it can start as early as January and end as late as November.

Tree pollen - late March to mid-May.
Grass pollen - mid-May to July.
Weed pollen - end of June to September

If there are specific toxins or enzymes in the water, ozone may be able to damage them and make them less toxic. Certain media can also bind organics, such as Purigen.

Randy, do you think hydrogen peroxide could be used as a "cure" in this instance??

An update.
My orp is back at a higher set level as before no o3 needed to keep it there
I switched on my o3 unit after orp dropped below 275. Several weekly water changes, use of GAC in a reactor, with Purigen and all is ok.

Did the STN stop too Dazza?

Good water quality, is it more than the common parameters?

I think common parameters are over rated and should be taken with a grain of salt, Maybe Instant Ocean.
We on these forums love to post our parameters but we also love to say things like, "My parameters are perfect but my fish and corals are all dead".
There are so many things that could be in water or not be in water that it boggles the mind. It probably even boggles Randy's mind.
My parameters, whatever they are most likely stink, yet my corals and fish are doing just fine. Seawater contains every mineral on earth and we only know what a few of them are for so those are what we focus on. But algae, bacteria, fish, corals and the air in our houses add things to water besides the common nitrate, nitrate, iodine, PO4 etc. and we can't or don't want to measure for these.
As tanks age they accumulate copper, lead and plasticizers from vinyl and plastic tubing and other things from our water supply even though most of use RO/DI. RO/DI doesn't remove 100% of everything and over time some of these chemicals are either a benefit or detriment to our tanks.
Randy is the Chemist and I am only a lug nut with a fish tank, but it is a very old fish tank with a lot of experience that came with it. This hobby is not cut and dry like stamp collecting and there are many variables besides common parameters. Just my un educated opinion of course. :wildone:

Yes the stn did stop mate!
I forgot to say I reduced my lighting par and length to allow corals to heal. I also used Coral Snow too!

Indeed there is a complex relationship going on in the tank - and the reason for the title as I have a near perfect ICP analysis of tank water and things have recently gone very wrong in my tank.

Back on track now - until next spring!

I was sure I posted a reply to this a while ago.

Anyway, it's impossible to say without knowing what exactly we are trying to "damage" with the peroxide, and whether that damage will happen to the toxin before it happens to desirable organisms. The good thing about ozone is the treatment can be carried out away from tank creatures. But peroxide, not so easily.

Thanks for the reply Randy

This is the problem that I have at the moment, which we have linked to these pollon problems
