A little while ago I asked the question if anyone on the forum had used these powerheads. I decided to purchase them after no responses mainly because the RW8s I had would not link up with the bluetooth and I feel were too powerful for my tank. The Rossmont stuff turned up from charterhouse and I was keen to inspect the goods. They were well packaged and nicely presented so it looks good before opening the box. I ordered the waver and two M3400 heads. All seem well constructed although the heads seem heavy.
The waver controller is compact and would be easy to hide in the cabinet or hang on the wall. I would prefer it if the plugs from the waver were on a longer cable.
You have two channels on the waver controller and a further indicating white LED. It says that you can master/slave other wavers if you wish but I have no need for that.
As for the power heads as I said they seem a little heavy but well constructed. I like the fact that the cage around the impeller has small openings making it harder for stuff to get in. Possibly even an anemone may struggle to shred itself. The heads are provided with a concentrator to take the flow from a 120 degree spread to 60 degree. I have opted to fit the concentrator for my needs. The heads were easy to install with a good magnet mount. I would say that you can't position them at a complete 90 degrees so if you want to direct the flow along the back of the tank, if like me have a centre weir and have the heads central pointing away from the weir it is not possible to get the angle but it was not essential. For my needs it is not an issue.
On to the set up, the heads can be plugged straight in to power supplies and would then run at max flow. Hence the waver.
Now this proved interesting as the quick start guide is not necessarily easy especially for a proven technophobe such as myself. I struggled initially with the set up I thought it would be plug and play but no. I followed the instructions which tell you to type in an IP address but then switched to my wifi which couldn't recognise the IP address, I was unaware that the waver is it's own wi fi effectively. I didn't think this was made clear. However contact with the help desk and I was sorted out.
You can embed the waver in to your own wifi LAN if you wish but I have chosen to keep it separate. Once logged on you can access the help manual and guide which are clear after a read, and you can soon understand how it all works.
I really like the range of flexibility the system has, down to fractions of seconds and 1% steps. Also you can use a preset menu that allows you to work out your own program and apply it to both channels. There is also the facility to allow you to select how quickly the powerheads ramp up and down from .25 second up to what ever you choose. You can pretty much work out wave effect to suit any need you have.
Further to that you have a visible graph that you can plot your flows to individual points all the way down to 1 second. It is important to make sure you save your changes and the select the tick otherwise your set up doesn't get applied.
Once up and running initially I have set up channels 1 and 2 both alternating at 65% for 300 seconds then ramp up over 6 seconds to 85% for 120seconds then down to 65% again over 4 seconds. This is my initial set up just to see what I think.
The power heads seem smooth and they are oh so quiet unlike the RW8s which I liked but could always hear the hum from them, and I felt were too powerful for my system. To sum up I like the Rossmont stuff so far,
Dislike:
Powerheads seem heavy.
Plug length on the waver is shorter than I would have liked.
Quickstart guide needs more clarity.
Likes:
Well constructed and well presented.
Versatility of the control
Compact waver easily hidden in cabinet or placed on wall.
I think they are value for money so far.
You could sit for hours and play with the settings.

So it's only my opinion and if I get trouble I will update. I am looking forward to more messing about with settings in the future.  :grin:

Must of missed that post...just had a quick google, as a rough rule of thumb the cheaper kit is heavier with so many things. Six foot lead for a big PH is a bit mean,you could knit a jumper with the leads on Tunze stuff but you do pay masses more. Also I didnt find they went the distance good as they were.


The concentrator nozzle....do be careful where you point it as strong concentrated flow is not as good as a wider flow ,like you get from say a Gyre. The more modern PHs have these wide mouths for this reason, possibly a better idea to get a bigger PH and not need the nozzle to increase the flow/force.


Dont hold yer breath on the nem sea hare front,these are two entitys that have a very strong suicide instinct ,rather like sheep...


Having said all this its just my opinion, its great having people trying all the differing makes on the market as it does help us all.

Hi @Angrymac  , Are these the new variable AC heads ? I've been looking at a small set of these too with the variable controller to accompany my two koralia's , will be interested to see how these have gone for you after a few weeks use and what your opinion is of them then .

@Carol Just thought they looked good for the money. I am going to try them without the nozzle as well. Because of my next tank taking a large budget I wanted something that wasn't going to break the bank. The lead off the power head is at least 6 foot its the leads from the controller that are short. Got to say I do like the control side of it. It gives you a lot of scope.

Yes I do agree,PHs are a dilemma, even if you have an unlimited budget,getting the quality controlability and reliability,whatever you pay seems fraught.


Id need more than 6 foot, I had to buy an extention cable for the furthest Jeabao from the controller.


With my stupid wide end braces the lead has to come accross then up ,so you can never make them look neat.

@Gav  If by AC you mean auto clean then yes but I am not sure how it auto cleans. If by AC voltage not certain will double check.

Hi folks been a while, well having had the Rossmont powerheads in for a while I have gone back to the Jecod RWs. the Rossmont ones are nice to look at love the versatility of control but the ones I had just did not seem to create enough flow even at full power. I would advise if you are thinking of them then go up the level and turn them down. Had a few problems in the tank and finally put it down to the lack of flow and not enough surface movement.
Do I think they are worth the money? Yes but the smaller ones are for smaller tanks than advertised, just my opinion mind.
