Grech Sun Sun Wave Maker JVP 130

Is very quiet used it for my marine tank easy to install and moves the water around well

Good flow output, low cost and easy to use magnets. These make the grech a cheap option for flow, however does make a small buzzing noise. So not entirely silent however not unbearable.

Before I start complaining, - this is a great value product and I recommend it, but read on!Pros:- Very strong magnet - sticks in place easily and holds securely, even through my 12mm glass.- Silent in operation.- Adjustable flow options using the sliding nozzle.- Power cable is long enough to be useful! No extension needed.- Power cable has preinstalled suction cups to stick to glass.Cons:- The power cable is really stiff and exits the device at an awkward angle.- The actual wavemaker is simply a friction fit into its mount. There are no screws to tighten it into position.The two cons combined mean it's difficult to get this to stay pointing where you want it. The stiff power cable kept pushing against the glass, turning the spherical wavemaker in its mount until it pointed down and forwards in my tank. This was annoying as I wanted it to point along the length of the tank. I eventually got around it by soaking the cable in boiling water for a few minutes to soften it up. I then held it in the shape I wanted it and put it into cold water, where it stiffened and held the shape I wanted.An easy, if annoying, problem to have to overcome.

I bought this wavemaker for my marine tank it’s very good and powerful and does the job.

Early days but seems to do the job intended

Great product if I could give 4.5 stars I would. The only negative with this so far is the power cable is a bit short at around 1m, limiting positioning within the aquarium. For my situation I could do with 2m power cable minimum. Otherwise I'm really impressed with it.

Fully recommend

Terrible product ive used it for a month and a half and the wire has came loose inside of the wave maker giving my water a stray electrical current. Doesent look like i can have it changed as the warrenty only last 30 days fair to say i wont buy anouther
