Marine Velvet, I can't believe its happening to me.

It was probably more due to introducing something in the tank without quarantine than anything to do with temperature rising.

Temperature cannot create a parasite, it has to come from somewhere and MV does not stay latent for months, it just strike. It would not be on the fish for months without any effect and then poof one day it goes on, it does not work that way, it just strike fast.

It could have come from a coral, from contaminated water, anything that has saltwatre could be contaminated.

If there are no parasite in the tank, then there won't be any outburst of anything. If it's not there, you wont see it, thus the importance of a proper quarantine.

My temperature rise, drop and everything and there is no ick or MV attacking my fish because there are none in my tank. The best defense against parasites is a proper quarantine, at least 4 weeks, better 6 weeks.

I'm curious to know if you think the underlying cause of this was due to the temperature swings? I have a similar situation. I also have a RSM250 (sumpless though) and now that it's warming up this summer finally the temperature is getting a bit warm. Normally sits a bit warm around 79 - 80. It's warming up to 81 - 82 now though. My fish have stayed healthy so far (knock on wood).

You have a lot of fish in a small space (16 if I counted correctly). Isn't marine velvet similar to other diseases where stress increases the chances of it occuring? You don't think this may have contributed?

The previous comment isn't meant to be rude or anything either I'm still fairly new to this and just appreciate the knowledge of experienced reefers in the learning process.

I hope things turn around for you.
