New sump issues....
I have a 15x15x30 tank which I know is small to have a sump I have been told.
I have a problem with either the return flow of water into the tank is so powerful that my tank has a mini storm going on inside it, or with a smaller pump the flow is not fast enough, so that the heated water is cool b4 it hits the tank. Any idea's on how to diffuse the water's power into the tank with the more powerful pump, without using rocks to diffuse it, as it will mean remodeling my whole tank.. Hoping this is written clearly, my terminology is not that good! |

I would use modular hose aka loc-line. Before it entered the tank I would split it into two lines each with a ball valve then once the loc-line goes into the tank split both lines into 2 for a total of 4 returns. It will slow the velocity down and the ball valves will let you dial it in.

First of all, that tank is not too small to have a sump. Here's my 14x14x14 cube that I built:
In the stand I have a sump that holds about 4 or 5 gallons and only has a filter sock, heater, and an eheim 1250 return pump. The 1/2" return line is split with a locline "y" fitting (not shown in the picture). The flow is enough to ripple the surface but not cause a sand storm. You may need a smaller pump or put a "t" fitting on the return line and let some flow go back to the sump.

I'm a bit confused by both your answers, I'm no engineer:-)
How will that help the circulation if not enough water is pumped into the tank if I use a more powerful pump? The water level is also not very high in my tank, due to a low amount of water being pumped into it.. |
