I assume you are having algae issues?

I've been doing the 3 day lights (just lights, I don't cover the tank for total blackness) out for a couple of years now with no ill affects.

yeah I'm killing off some algae, half is already dead since I started doing water changes with RODI water but I want to speed up finishing them off :)
i'll give it a try, thanks :)

TBH I wouldn't do a black out. I would keep doing the water changes and it will eventually dissipate. Killing algae off quickly could cause some issues? Be patient, keep up the water changes and before you know it, its gone.

well it is dying off at a decent rate. compared to the forest it was, it's like a garden now lol.
you mean phosphate release back into the water column?

Not really sure, maybe some nitrate increase, but you know the saying that nothing good happens quickly in this hobby. Manual removal of algae and water changes with RO/DI should take care of your issue.

corals do get stuffed in a box for a week or two then go to a low light holding facility, so I wouldn't worry about light too much.
weakening the algae with nutrient reduction and light reduction imo is a fine plan, but get it out of the tank as soon as you can, dont let it languish in the system.
I use a chepo canister filter w floss only like a shop vac when I deep clean.
Itn not likely No or Po being released from the algaes thats bad its possibly the iron, hormones and chem complexes and everything else that "may" cause you some probs.
Did you know, that the smell of new mown grass is mostly made up of hormones released when the grass is damaged esp when eaten. Its a chemical marker sent out to warn the rest of the colony and they in turn produce a bitter taste to reduce predation. Yes the grass is screaming.

Not to hijack the thread, but they're discovering some amazing things in the relationships of plants to each other in forrest ecosystems as well, not sure if you are familiar with "Mother trees" or not, and the symbiosis of trees/plants and the Myccorhizal fungus. Talk about interesting movement of nutrients and CO2! Exciting stuff! Carry on with the thread now :D
Im actually very familiar. we have discovered that plants talk. and "think"
I wonder what corals say? I haven found a connection yet in the marine world like the fungus. I assume as its more primitive its only chemical linking.
to tie the thread back together with this, good flow the correct amount of light and cal and alkalinity encourages the development of coralline algae, by balancing light minerals and organic nutrients,and even though you dont see it(macro fauna) it is important as it sends chemical signals to the corals that its a good spot to grow. This can be seen in the hobby as many say the acro growth took off once it encrusted the plug or encrusted the on the rock. some use rubble or seasoned plugs to place the frags on. I do. or glue them to the rock.
This corraline chemical and light method is also used in breeding and spawning corals as well as the breeding of abalone along the coast of california. its likely this will be how we eventually breed corals in captivity.
eventually maybe oneday Ill shift my lighting schedule in a tank to replicate the daily time shift and temperatures to match the seasons rather than just my perfect day in Fiji everyday. Good news I may make my corals spawn, bad news I wont see the tank much in the winter.
