| My plan of day (for 90gal) is two tunze stream 1650gph (I think) on alternating 15min periods. Plus the return ~500+gph. That alone is over 20x volume but I think I need a little more for some variation. Maybe a small Seio or somehting that could be directed in the rear of the tank to avoid any dead spots. Or maybe a cheap zoomed powersweep in the corner next to the overflow. Its less than 300gph but does sweep the stream back and forth and woudl probably help avoid a dead spot there.
Any input is appreciated. Are the tunzes too much from a single source for a 90g? Would this create a good environment with enough variation? |
