I am gonna go with the bottles! Now I have to start collecting a few...or I can start with the beer bottles and replace them if I find more interesting ones!
Took a while to clean everything and fill it it with water...hubby decided to haul city water for the tank instead of using our well water...
...I plugged the 2 Emperor 280s in and that was interesting! The first one wouldn't prime and was making an awful racket...so I fiddled and fiddled and finally got it going...
...the second one wouldn't even start...but I managed to 'unstick' the impellor and it's running...but it's still too noisy.
I don't know how long the filters were unused before I got them (not THAT long, because they still had water in them

)...
I'll let them run for a while and see if they 'settle in'.
I only used half the gravel I bought too...25 lbs covers the bottom completely and will be easier to vacuum then twice the amount...
