Limpid- In regard to the lighting, I would not trust such an investment to LED. This is just me... You will have to read back to my issues with the LEDs... Long story short, it will be years before I trust any LEDs to run on my reef tank EVER.
I am not even sure if I would run a FOWLR with them. Too much film/nuisance algae for me.
From what I understand, clams are mainly photosynthetic when they reach a certain size... I have heard variance as to what size but I would assume anything over 3-4inches? I think that LEDS are strong enough, if you have big enough LEDs... Put it this way:
I would not have a clam under anything less than 100 watt MH lights or the equivalent - - unless you had a shallow, lagoon style tanks. Something around 14-12 inches deep? If it's anything deeper, like a standard depth tank, you will need strong light to penetrate the water and get the right PAR down to the sandbed, which is where the clam resides.
WOW!!!!! I"ve seen a tank first hand Dr Macs clams grown natural sunlight in 48" deep vats.......Not getting your theory or logic with the statement.....
This is all just my opinion though. I have never had good luck keeping anything under LED and I have had good luck with coral under T5HO but not clams.
MH is the only thing that has worked for me.
I think you might be way off on that statement.....I don't know what LED units you have experience with, but I'd be willing to put money on it, that quite a few of the units out there would blow "the MH" theory out of the air......Heck even a DIY rig with the new 5w would blow MH's out of here.....That is a fact...
You gave a very broad statement and again I'm not sure what LED units you have experimented with, but as we all know there is a tad more to the "picture" than just lighting.....Lighting is just a small part of things....You could argue that you could have 2 identical tanks running....just different lighting setups, and you'd see different results possibly, and the 2 tanks wouldn't be identical.....Honestly you can't argue they are a risk.....Heck there are tons of tanks that are SPS dominant and have no issues, that's why I argue it's not all down to the lighting.....Acclimation is a big key that many of us are still side stepping causing issues......
There's a thread from way back on RC.....a die hard, reefer.....Tank is totally sick for better words....He swapped from MH to LED and had the same thought and opinions as you at the end....Tank went downhill, but if you go back and read through things you couldn't whole heartedly say it was the LED swap.....There are to many variables that changed in a given time, and you can't honestly say things were dead set rock solid when you did make the changes.....No variations or deviating of parameters etc......Acclimation was done correctly........
