whats you flow?

Says a lot about flow...less but more random has been very good for this acro. Same thing with the digis I have all over the tank. Ones in low flow grow much faster and higher while the ones in high flow grow thicker and diagonally almost.

as you both have seen there is a lot more to flow than just the amount, you also have to achieve a masive water movment with out blasting with a slight up welling. I had to fiddle with mine for about 2 months to get the growth and shape I wanted and if you have sane forget it as now you are putting that flow in the top 1/2 of the tank so you are realy doubling it in that area.

even with a 144X turnover in my tank, you could put your had anywhere (aside from directly infront of the pumps) and only feel a gentle current anywhere in the tank.

Tunze 6100 (~3,000 gph) alternating with a modified Tunze 6055 (~1,800+ gph)
Eheim 1260 return (~250 gph after head loss etc).
Wavebox

So at most about 3,250 gph of "primary" flow at any one time.

120 gallon display = ~27 times turnover.

Mixed reef on a Gyre flow pattern.

total of 400 gal
pumps add up to 18950gph
= aprox 47.375

33g LPS only. No sump.

Koralia 2 (600 gph)
MJ1200 (300 gph)

A couple small pumps running hob filter for carbon and PhosBan reactor which according to manufacturer's ratings adds another 300 gph to my tank, but I won't add them in because their flow is very indirect.

900 gph total = 27x turnover.

It's kinda tough to compare turnover and flow because the pumps are rated so differently especially when you compare impeller driven to propeller driven. So it's good everyone is listing the brand and model names. My MJ1200 puts out more "flow" than the Koralia 2 even though the Koralia is rated as having double the output of the MJ.

It would be tough to get two MJ1200s in my tank and not have my LPS freak out, which would only be 600 gph total going by manufacturer's rating and only 18x turnover. If I had two Koralia 2s I wouldn't get enough flow, and that would be 1200 gph total or 36x turnover.

200 gal SPS

2xTunze 6100 = 6800 gph
2xK4 = 2400 gph
1000 gph return

10,200/200 = 51x turnover per hr

Will be adding wavebox
