Ok got ya.
My mesh cups I ordered come with the foam collars.
I think I will be all set then.
Thanks Blue

edit, Blue, I already have 360 watts of solar panel's for the house and I charge 8 - 6v golf cart batteries, and 45 watts of solar panels for my 12x20 barn .
We run the 2 tv's, stereo, xbox, dvr and surveillance cameras all day and night.
My electric bill for a all electric 4 bed room house has been less than $70 for the last 4 months.
It can super easy handle 20 watts from the pump. My LED I built is 200 watt 24,000 lumen and uses 188 watts.
I will be finishing a 150 watt led grow light soon using 2-50 watt warm white chips and 1 cool white 50 watt LED chip.
That should help cut power usage a wee bit more. Free power is killer, after the initial cost to set it up..
