Figured some may appreciate the newly tossed together frag tank...
(Ignore the cup - did you know eggcrate floats?)
Not much to look at just yet - 23g tank, quietone 1200 pump, 3 hydor flo's built into a calfo manifold.
Flow is very random as one might expect, the hydor's do a darn fine job. FWIW, before I believed that hydors clipped right into a 1/2" FPT, but that's not quite true, they clip right into 1/2" bulkheads. So for this project I used marine goop to glue the included adapters to the 1/2" slip x fpt T's.
And just for some useful information...
1/2" 90 - adds 3/4"
1/2" T - adds 1 1/4"
In other words, if you have a T, 2 90s with 2 5" pieces of PVC - total length will be 12 3/4"
