i use one of these monsters for my sump to scavage around and i was wanting to put in a few peppermint shrimps for some mewly discovered aiptasia's, can this be done or will they fight?

 

[trottman]

you would be better off leaving the aptasias in your sump and putting in a UV sterilizer between the fuge and the return pump.

that is what i am doing.

i am using aptasia, sponges, feather dusters, many different worm looking things, tunicates, scallops, and other detrits feeding water filtering organisms to naturally filter my water. i have all of this stuff located in my ""fuge"". i built a rack out of egg creat, that fit in my sump. i then piled all my lr rubble on that, which created an open barebottem dark area below that. this are is where are these organisms are located. (it is not black there, some light does still get down.

then i have my uv between that and my return pump to make sure that none of these organisms can reproduce via releasing eggs or whatever into my display.

i have way too many pods that would die due to this,

 

[trottman]

if you have way to many pods then you dont need all of them

I think he meant he had a good population he didn't want to start killing with a UV filter.

levon15
exactly, i have a good population the most i have ever had in any of my past setups.

Dr. Rhodes of Oceanpods.com says UV sterilizers will kill very few pods as they are highly protected against UV.

 

[Indermark]

how would the pods be highly protected against UV rays? Just wondering not saying your wrong. I would imagine when the UV light gets older its not going to work as efficient or if you use a lower wattage bulb.

It has been demonstrated in arctic pods (think of how red Cyclopeeze is) that they can change coloration to combat the oxidation effects of UV radiation. I have recently helped out in a marine lab near my place in Santa Cruz and I placed a filter on the outflow of water which was passed through 2 sand bed filters, 3 canister filters in size ranges from 100 microns to 5 microns, and UV filter - guess what - there were still copepods coming through. We figured there was a leak in the canister filters, and the UV bulb was replaced, I believe to increase the chances of removing any remaining pods. These guys are tough!

thats really interesting, I may consider getting a UV and see for myself but thats something I really don't need right now. Thanks for the info.

i have had one NIB for 4months and have been undecided to use it because of the loss i could suffer from the UV,if it does kill the pods maybe when i see more in the display not just in the sump.
