I hear ya, that's why mine sits on the shelf....

I understand it's not a cure. But would the benefits of decreasing the chances of an outbreak outweigh the killing of some microscopic foods?

Maybe running it off of a separate, slower pump instead of a return.

There's gotta be a good reason so many large and successful reef tanks run 1 or multiple sterilizers

hey man shoot it on the bus for me to use. i dont have one
:cry:

i used to always use Ozone in my beckett skimmer and and always never had any issues with water clarity and ick. However i may go back to either Ozone or UV since i have a smaller tank and things always change rarely fast as I'm seeing.

From what I observed with MV, no, it wouldn't help. The outbreak has already happened, so adding anything at this point isn't going to prevent an outbreak. If it's MV, the only viable option to save fish is to catch them, put them in a treatment tank and treat aggressively for the pathogen. Or let it run it's course and see what's left on the other side. However, fish can build an immunity to MV, so while you may feel some fish are safe at the end, adding a new fish could set it all off again, with the old but infected immune fish infecting a healthy new fish.

Up date to the mv lost the baby clown.

prawn Goby, mystery Wrasse , yellow wrasse, zebra dart fish, have not been hit with it.

the other clown, female , bangii, female Labouti wrasse are fighting it off pretty good so far.

keeping the temp stable so far still think that a chiller is in hand.

Mike how many fish have you lost in total?

Sorry to hear about your losses. That's awful.

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.

Hmmm! Kinda thinking the same thing here. I started with a 72 gal and the summer heat never affected it in the slightest. No sump either. That is a lot of fish in there. Not sure how big your sump is but I am leaning towards it being due to stress like lee9 said.

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.
