Rio seio

[I'm gonna take the plunge and get one of the M820s. I'll let you guys know how I like it when I get it and put it in my tank =) I plan on putting my existing powerheads on a 15 minute cycle and using the SEIO 24/7]
 
[Joe T and I ordered some last week. We'll be trying out the 620 and 820 models. Was able to get Marine Depot to match Custom Aquatic's lower prices but not able to obtain the MD free shipping promo. I stayed with MD as I have not ordered from CA before. Both CA and MD does not have any availability info on the other models of the Seio line.]

[I called MD today to verify they had the 820s in stock. She told me they had more than 50. Hopefully I'll be ordering tomorrow. It's looking like I might have to hold off. Not sure yet.]
 
[IMO they were not that great. I was able to get rid of a couple dead spots but I think a couple more maxis would have done the same thing.
THey are also very larger if you mount them horizontal without the direcional bracket.]
 
[I guess I will keep them and hope the new impellor makes a differance whenever they come out.
A lot of my problem is that I had nowhere to mount them. My tank is sooooo full and I did not want them on the front of the tank.

All told 4000 gph turnover still has not got my sand to move. Maybe I will sell them and try a tunze, but they are even LARGER.]
