Downgrading from MHs to VHOs

[brewercm]

I like that idea as you can always use your existing VHO actinics just for that purpose and with the others you give yourself some bulb play to see what you like. If you'ld like you are welcome to come by and see what my 58 looks like with the 5 bulb system over it. Quite a bit brighter than I figured it was going to be.

After talkig with Barry from Clams Direct a few months back he had told me clams would do fine under the system I bought. I'm not planning SPS but wanted to keep clams this time so I just wanted to make sure the lighting would be adequate.

You are correct about the 430. Here is a quote from icecap, ""With the 430 ballast it will run 2 T5's only regardless of wattage. It will not overdrive them to the levels of a 660 ballast. It will be minimal at best. Will overdrive them by approximately 10%."

Thanks for making this simple. folks.

Thanks for the fixture recommendation - I have plenty of room to mount, so I don't need one. I also like the ability to fix components when they break. As well, I mount my ballasts outside (protected from rain), so they don't get salt creep and don't put heat into my tank/room.
