Very disapointed in comline 6208

[hounddog01]

I bought this for its size and everything I read was it would work with a 200 gallon tank. I have a 180 72x24x24 and can not even generate a small wave. I was able to generate a small wave with one mp 40 so thought the wave box would do a good job. I even turned off all other pumps and moved the wave box up and down so the water line was where it is marked and above and below it. no matter what I tried I can not generate a wave. I put in in the back first then in the front corner of the tank, both had a direct line to the opposite end of the tank. I have purchased tunze products for over 10 years, this is my first disappointment. I was so excited to get this hooked up and now well just disappointed. if there are any suggestions I have not heard I am all ears. I cant believe this was not tested on a 6 foot tank when it is rated for 200 gallons. :headwally::headwalls:

Something has to be wrong, it will definitely make a wave in a 180 that should be about 1/2"-3/4" high and in some cases 1" will be possible. Let's start with the basics.

1) Do you have the wavebox installed so the top 3/4-1" is out of the water (marked line)? This is very important, the wave will be very short if it is fully submerged, the box is supposed to empty and the displacement adds to the wave. It cannot empty and displace water if it is fully submerged. Again, I know you mentioned this but to be thorough, please double check this.

2) Did you set the power supply to 24V? In general the power supply comes set to 20V and you had a bag of jumpers that came with it, 12, 15, 18, 22 and 24V, the higher the voltage the bigger the wave.

3) Is it positioned so it is aimed down the length of the tank with a minimum of obstacles in the way of the pump output? I know you mentioned this was checked, but it is important.

4) Is the frequency properly tuned? The range is .30- 2.00 seconds and only one exact frequency setting will produce a wave, you have to get this dead on and auto tune should make that fairly easy, on a 6ft tank it is usually between .50-.75 seconds. Once you get close with auto tune, fine tune with the + and - buttons to maximize the wave.

5) Have you verified the pump is fully assembled? The front housing can come off in shipping and the pump will be very weak in that case.

6) Keep in mind that end overflows reduce wave height, the wave will spill over and lose height, damning them up to barely below the tank level with Durso or stockman pipes will help.

7) Some rock layouts, especially a wall of rock along the far wall opposite the wavebox will dramatically reduce the performance.

I retried all of this and with no results. The pump is pumping and I even turned the pumps off again. I have an acrylic tank so the water level at the line is almost impossible with the pumps on. I put it back in the front of the tank where there is no obstructions on the other end. I tried auto tune to no avail. I used each of the tuning times for 10 minutes each with no wave. I would not think a person would have to go thru this much to get a product to work.

I am sorry you have had a rough time, the waveboxes have never been an easy product to set up. They are intended for more advanced aquarists and setting the resonance frequency correctly, while much easier with the 7092, does take some patience. I can promise though that it will work in a 6ft 180 tank and quite well, I think the main issue is likely that the tank is acrylic and setting the box height is difficult, this is an issue on occasion as acrylic tanks tend to have very little space from the water line to the top frame. I don't really have any further suggestions, but setting up a wavebox does generally take some hours of tuning and it is not a quick drop it in and go and it may just not work well with your tank due to the water level/bracing.
