Are phosphates as high as 0.21 a potential cause for stunted recovery in corals? My red monti has been bleached for a few weeks and, while it hasn't gotten much worse, it also hasn't gotten much better. And my gorgonian also has been depleted of its skin, though when I first bought it, it showed no sign of necrosis.
With a monti struggling you’re gonna have to post your water params, sorry
Yes, absolutely. Phosphate that high will inhibit the corals ability to calcify. Here is a good article.http://reefkeeping.com/issues/2006-09/rhf/index.php#5
Nitrates: 0.5 ppm
Alright, so what can I do to consistently keep my phosphates down? I feed my fish once a day, and put plankton in for the corals three times a week. I'll also throw in an occasional piece of silver side for the inverts. Lately I've cooled it with water changes, mainly because I my nitrates seemed to be way too low for corals, but before that I was changing 2 gallons of water every single week. Should I get back on that regiment?
Alright, thanks for the tip. I'll see what I can do. By the way, I love your username and icon
So here you say nitrates are 2-5 then few posts down you say nitrates are .5 that’s a huge difference and probably the problem
Why would raising nitrates with a high alkalinity be the solution? How do alkalinity and nitrates relate to each other in regards to coral?

I'm not so sure nitrates are the problem here. I never heard of 0.5 ppm being dangerously high, and it's only the gorgonian and monti which are having issues. My mushroom, candy cane, and duncan have been doing great in comparison, with the duncan even sprouting more heads.
If it was my tabnk I would be looking at some other cause than PO4 being at .21 mg/l. Phosphorus can be a hotly debated topic sometimes. Here's some of the research showing it's effects on corals. A couple of the findings by researchers is corals photobiology can be severly impacted with too low of phosphate and a threshold level of .03 has been identified as a minimum level to avoid the risk of this happening. Research has also shown increasing PO4 levels increases growth. More and more research is showing a corals microbiont is critical and disrutptions can cause problems as well as nitrate potentially can cause bleaching.

Nutrient enrichment can increase the susceptibility of reef corals to bleaching - Nature Climate Change
Increased dissolved inorganic nitrogen (DIN) concentrations in sea water have been linked to a reduction of the temperature threshold at which corals bleach, however, the mechanism underlying this change is not known. This phenomenon is now explained in terms of increased phosphatase activities...

Sponge symbionts and the marine P cycle
Marine sponges are ubiquitous colonizers of shallow, clear-water environments in the oceans (1, 2). Sponges have emerged as significant mediators of biogeochemical fluxes in coastal zones by virtue of respiring organic matter and facilitating both the consumption and release of nutrients (3, 4)...www.pnas.org

Yeah I know... I really screwed up with this. I'm actually amazed at myself that it took me this long to realize it.These are a huge concern for me. I've settled on grape seed oil as a very good, realatively cheap mosturizer and to avoid some of the stuff in hand sanitizers that is not only harmful for aquariums but some are potentially damaging to the environment when they break down into dioxins I use H2O2 in a spray bottle, if any get's into the tank at worst it may kill off a little algae (oh my!
The tank is over 18 months
