4. Turnover rate: 29x/hr according to the head loss calculator on RC

1. Please give your type of tank: frag trough

3. Pumps and GPH rating: Reeflo Dart (3600gph), Mag 3 (300gph), Koralia 4 x2 (1400gph), Koralia 1 x2 (400gph), Iwaki 70 (1500gph @4')
4. Turnover rate... ~60x/hr? after head loss

2. 300g
3. 2xTunze 6205, 2xVorTech MP60, 1xTunze Wavebox, 2xEheim 1262 (returns)
4. With all of the pumps running at Maximum flow, the turnover is over 100X

It's always interesting to see what other reefers do
here's what i run on my home tank
1) mostly sps tank
2) tank volume is around 440 ish
3.1) reeflo sapper for return(1800 ish after head lost)
3.2) reeflo hammer head for close loop(5900 gph)
3.3) 6 mp40w (19200 gph)
3.4) 8 tunze 6055(11624 gph)
3.5) 2 tunze wave boxes(i think it's around 6400 gph)
4) at max flow about 102x hour

i would think average is around 70x hour:biggrin:

Oh sure - your flow has to be 2 more than mine. :smile:

Having seen your tank, whatever you are doing seems to be working. Maybe I should add another powerhead to get my flow up to 102X? :razz:

i am waiting to see how the mp60 works for you first lol, i may end up pulling all of my tunzes out and run 4 mp60's with my other mp40's. Just not sure yet, lot of money to do that change:cry:

LOL dude ur gonna have to cement all your rocks down :lol:

40g cube
will be mixed reef
2x Koralia 3= 1700
1x sedra 5000= 400 after headloss
2100 gph = 52.5 x turnover.

200 gallon DD

4 mp40's in master/slave reef crest setup = 12800 gph
water blaster 5000 with head loss = 800 gph

total = 13600 gph or 68x
