i answered you again in another web and copy one more time la
浪 - created by resonance(共鳴).......7091 cannot do it, as need to control the pump start /stop alternately (交替地 開/關)........you need to use 7092 or wavebox to create 浪
水流 - can use 7091
your tank is just 40" FOT, if you like the wave effect very much....just buy one more tunze wavebox (already included controller), then you can hv 流+浪 effect
you try try first la.....if you dont understand the theory of resonance(共鳴).......then you may need to read some high school physics book la.....
sorry galaxy ching, my one should be 7092 instead of 7091.....7091 cannot be used for WAVE control, which can control the CURRENT only.
but as far as i know tunze stop the 7091 model for long time and replace with 7092 (even do not hv 7091 in their website)
ching just buy it??.....should not be the old model??
but my suggestion is still okay...as you need to buy one more set for wave in any case.
i am using 7091 and two 6105 on my tank, also one tunze wavebox........
for me 7091 and 6105 are great......if you do not hv wavebox then 7091 can fine tune your 6105 for wave without any problem......but once you use yr 6105 for wave that means you need to buy one more 6105 for current (and one more 7091)......like other ching said 7096 should be a better choice as it can control upto 4 tunze pump
7091 - can use as wave control OR current control (it cannot produce current and wave at the same time
also you only hv one 6105 so you can either use it for "wave" or "current"
setting - actually tunze menu is very clear for both wave control OR current control (also another ching hv explained to you la.....) in detail fine tune...you can only do it by yourself....as all the tank is unique and also depend on the effect that u like....
if your tank is big, i would suggest you to buy one more (pump or wavebox) as the effect will be better....if u buy pump then remember to buy one more 7091 or 7096..........if u buy 7096 then you can sell the old 7091 in 2nd hand market.......
u said u wanted to buy 6095 on your 40", that's fine, at last u bought 6105, that may be even better
for the controller u bought 7091, not smart this time, I have 2 7091, I can only control pulse or not pulse with it, not even very successful in controlling the size of the wave, 7096/7095 are far better
