I didnt have the algea poblems in the first place, my critters kept it under control, now I have the same no algea situation, but i do not use the critters, It just is not growing. That is the difference, I used to add things to keep algea under control (snails, crabs, etc). I never used phosban or any other additives, I try to maintan the tank without that. Now instead of adding things to lower my levels, I feed more to purposely raise them.
I still use snails (6 of them to be exact) and I have a couple of scarlet hermits that have been with me a few years and i enjoy watching them, but I would never want to have to rely on them for algea control. Just because they eat it and it is not visible, still does not help, they just poop it back out and it ends up on the glass (or in your sandbed). Both systems are clean, one just has much more critters and much more poop and I have to watch how much I feed, The other has few critters hardly any poop and I can feed much more.
Again, cooking was not done to solve an issue I was having, it was done because after watching tons of crud fall out of my rocks and piles of snail poop on the glass (and yes, they poop in insanly high amounts for their size, especally the trochus I prefer to keep). I wanted to not have this crud in my system. This is rock that was new, this crud came on the rock, it was not do too bad husbandry. I used a natural process to remove much of the crud (not the critters) in the rock. IMO Phosban and additives are not natural, but neaither is a glass cage

.
Cooking is not a "quick cure" extra snails, phosban and dropping your feeding to (visually) suppress a problem is a "quick cure". One system removes the stuff that is feeding the algea, the other just converts it to poop (which is a food for algea) If you do not believe me that it is there, dont clean your sandbed for a few months then stir it up all the way to the bottom, you will get a storm of crud, and this crud is not all sand and critters, a good portion of it is poop and shedding from your uncooked rock.
If you have a choice between rock with extremely minimal detritus or rock that is full of it (and if you dont believe me that is it full of it then blast it with a powerhead, or take a piece out and put it in a clean white bucket full of clean water and blast it). Why not use the one that is cleaner?
If you (and I do not mean anyone specific) removed 80% or most of your snails and just did 10% weekly waterchanges, fed your fish and corals, no additives, phosban, cheato, etc (besides cal, mag, trace minerals for coral etc) would your tank still have no algea growth? This is how I maintain my system (plus skimming) and the rock is bare.
I have yet to add coral to the system, there are just some zoas that survived the cooking and a encrustin monti I kept from an older system, but I can post some pictures of what the rock looks like to give you an idea of how "undead" but alge free the system is. The system is 4 months old, but it is just an equipement upgrade from a 2yr old system, so the rock has looked this way for quite some time.
