Hi @Timfish Thank you for this post I need to get to reading through these links. I love stuff like this.How many of us can test for all the forms of carbon, organic and inorganic and particulate; all the forms of nitrogen, organic and inorganic and particulate; and all the forms of phosphorus, organic, inorganic and particulate? It is a lot more complicated than just nitrate and phosphate.

Hi @Timfish Thank you for this post I need to get to reading through these links. I love stuff like this.
I have to ask do all these papers just refference back to old papers and other peoples discoveries and such?
I seen your post in another thread about the effects of Nitrates on skeletons in corals.
Is there anything out there on the effects of Nitrates in soft corals?
I have this mushroom that did absolutely nothing in 0-5ppm Nitrates and looked like this-
. . .
I bumped my Nitrates up to around 15-20ppm and it exploded within a matter of maybe 6-8 weeks and looks like this now
. . .
Only other changes was a slight increase of maybe 25par but has to be considered i guess but mushroom acts a little deflated in less Nitrates.
Is it cancerous amd should I be concerned that this shroom is gonna just die on me sometime?
Thanks Tim. You know I cant say positively that that shroom would have done what it did with or without elevating nitrates. Considering its most likely a Jersey bounce that morphed to what it now from what it was then and I haven't seen another morph like it.You're welcome! Most of the papers I refference are published papers by the researchers who did the research.
I think Rachel Wright's research with Acropora millipora shows ideally we need specific husbandry data at the genotype level if not also at the variety level.
Regarding your mushroom what would have happened if you didn't dose nitrates Would it have done the same after 6-8 weeks? Because it can take weeks to months for an animal acclimate.
Many soft corals have calcium spicules in their tissue. It seems reasonable to me, without research to the contrary, it should be expected to affect their calcification also.
The second problem with nitrates (Rohwer discusses this in his book "Coral Reefs in the Microbial Seas") is it removes the corals control of the reproduction rate of the zooxanthellae which frees up most of the photosynthates to be used by the animal. Considering a significant portion of a the mucus coating an animal with algal simbionts is derived from the photosynthates, the mucus coating is an essential part of the animals immune system compramising it by reducing the amount of photosynthates available for it doesn't seem a wise thing to do. Some coral obviously can adapt or adjust to high nitrates but that doesn't mean it's what's best for their health.
As far as the "bubbling" what you're seeing is caused mostly by excess blue light making it a "Bounce" mushroom. This will happen with other corals also. I've thought in the past like many others it might be a virus (kinda like illegal broken tulips) but research still needs to be done.
