I just bought an 80 gallon tank and it has the Marineland Jetstream overflow and return system in it. I was wondering if anyone has ever seen one of these before and if it works well or not. I have learned it is much easier to make modifications to the tank before filling it.  So if I am not going to be happy with it I would like to just put a standard overflow in it now.
It sounds good in theory but it seems pretty flimsy to me and in the brocure/manual it says the "optimum flow" for the drain is only 300-600 gph.
Here is a link to it: http://www.marineland.com/products/consumer/con_jssuper.asp - http://www.marineland.com/products/consumer/con_jssuper.asp
except I only have the two pipes (1 drain and 1 return)... not their entire setup.
One other question... the tank is drilled with 1 inch bulkheads... I was planning on using my mag7 which has a 1/2 inch outlet. Would I be ok with using that or would my flow be severely slowed by jumping from 1/2 inch to 1 inch? ------------- Immortal |

Your flow (GPH) won't be affected by going from 1/2 to 1 inch, only the velocity of the water coming out. ------------- Anthony 55 gallon reef |

If you are pumping up the weight of the volume of water being pushed will increase thus decreasing the gph. If you are pumping horizontally or down it will only change the velocity as Anthony stated. I use a Mag18 on my 72g with 3/4 out from the pump and 1" return to the sump. ------------- Kevin Kunz (Sandy, UT) 300g reef "A trade by which one gains and the other loses is a fraud." Ayn Rand |

| I would agree with Anthony. Having a larger pipe would not decrease gph if the height is the same on both pipes. The amount of head pressure is what determines how much it can pump. Head pressure is detmined by the vertical height of the water and any turns the water has to make in the pipe (90 degree turns), not by the volume of water above it. |

I don't want a large pipe sticking up in my tank. With my luck I
would snap it off the first day it was filled. In my experiece
you want the drain larger than the return. If it were me I would
put an overflow around the drain and go with a modified durso. It
return could be plumbed with flex pvc and directed to a spray bar, Sea
Swirl or any number of possibilities. JMO

I don't like these flimsy parts so I am going to just have an overflow put in on the one side and use the other hole for a drain for a closed loop.
I have never had a closed loop before, how many returns should I have in a 80g bow (basically a 72g but an inch or two taller)... Would 2 be enough or would I want more? This is going to become my reef tank so I want lots of water flow to keep the corals happy. ------------- Immortal |
