Big Derasa spawning, can this affect the water parameters?

[Dnoob]

My Tridacna Derasa started to spawn for some reason yesterday. When the clam is bigger than my head I started to think can this affect to my water parameters? All of that biological material will start to rotten in the reef. Almost 400g of water turned to white really fast. Now the water is back to normal, but the biological material is still there in the circulation.

It definitely can affect water parameters. With 400 gallons of water your a little safer but I would keep a close eye and be ready for a water change if needed. That's a nice tridacna!

Other thing that I was thinking is the reason why it does that. If I have understand it correctly it can do that if the environment is perfect or totally panic reaction. Luckily I have only one because when one start to spawn every clam responds in the same way. I have to take a look at the tank for the possible negative reactions. It seems that no one took the hit because of this.

It can be a natural response from the clam maturing or a last ditch effort for survival. I don't think it's your clam dying however, looks in great shape.

It was a little fuzzy Yesterday

The first few times mine did this I was very concerned. Now it seems to happen 1 or 2 times a year. With this last being the largest. Once every 15min from 1pm to 7pm everyday for 8 days straight. The only issue I had was a little cyano outbreak and a bunch of healthy coral. Of course every system is different.
Perfect timing on your picture. It looks awesome!

Now it's seems to be happy. I was lucky to be able to take that spawn picture. Timing was just perfect

Mine does this periodically. I end up with a literal whiteout in 90g though. Some nutrient bump but nothing else.

Mine don't cause any issues. I have two of them, but no baby clams yet. I do have a lot of skimming and stuff and the cloudy water is usually gone in the AM. I don't really measure building blocks, so no idea about that.

I imagine that this is all lunar based, but I don't have any kind of lunar stuff on my tank. I guess that it can maybe see the ambient moonlight or sense a change in pressure? I have always wondered how they come to know that it is time. I know that Knopp has written, but that was about wild clams, not the ones in my basement.

The biggest issue with spawning events is oxygen depletion... though in 400g you should be ok. Here is a good article explaining it:
