My review of the new WaterBlaster HY7000 pump

Great thread- thinking about purchasing the 7000 for a 180 gallon with the sump in the basement = 12 foot head pressure. - chart says about 2181 L/H (575 G/H) at that height. So, not great flow by itself - will need to have a few internal flow sources. I may have to bump up to the 10000 model ( about 800 g/h) - comments?

good luck,
I tried to run externally but was unable to get 3/4" plumbing hooked to this pump in a manner that didn't create micro-bubbles
let me know if you can get it to work

I already had my sump plumbed with 3/4. So I went sump-> 3/4 ->1.25 -> pump
I think going from 3/4 to 1.25 into the pump caused it. I have it reduced down to 3/4 for the return. I now have it in the sump and its fine so I think the bubbles were being caused by the scale-up before the pump.
I would think you would be fine since you are bigger going into the pump

I don't think the 7000 will pump up one story sufficently. I am running a 10000 from a basement sump up to the 1st floor at about 14' of head pressure. 1" all the way up and then manifolded to two 3/4" Sea Swirls.
The 10000 gives me enough head pressure for this application and I also tee of at the pump to feed my needlewheel skimmer.

ya- I kinda came to the same conclusion - the flow charts are in Liters and not gallons- so I did not covert in my head correctly. I need the 10000 model for reasonable flow for a 180 gallon tank at 14 feet head pressure- no doubt about it. Anybody using this model for any length of time?

So how are these pumps still doing... are the quiet ones still running quiet after a few months of use???

I have four different sizes of these pumps and the characteristics of these pumps actually quiet down after a break in period, they do not get louder over time.

Thanks for the update! They sound like great pumps! I'm looking for some to replace my eheim 1262s.

thanks for the review garage
im doing a 225 build and was thinking of using the 5000
and also looking to save some hydro
do you think the 5000 is enough for the 225 or should i go with the 7000
thanks

Vic,
Go with the 7000. I have been following your tank on AP and strongly suggest it especially with the tank size you have.. I would respond on AP but I have been banned.
I recently set up a 225 (72x30x24). Its been set up for about 3 months. You can always throttle back, but you can't get more flow.
By the way I used about a 60% of LR to Dry rock, you should seriously think about doing the same, my Dry rock is looking more and more like LR everyday and I would imagine in 1 year you won't be able to tell the difference. If you want to check out my setup feel free to PM me, I am in Hamilton so not to far away from you.
I own 4 water blaster pumps and haven't had a single problem with any of them. As others have stated, quiet, energy efficient and 3 year warranty...how can you go wrong?? I just wish someone local would supply these!!!

I have owned both the 5000 and 7000, I personally see no reason to go with a 7000 on a 225 as the flow is pretty crazy for a return pump unless your using a sea swirl or something to that effect. The 7000 turned my sump into white water rapids lol, which is why I went with a 5000 on my new 225 build and previous build. The point is not how much flow you have from a return, it is a proper amount of smooth flow to limit turbulence, bubbles and so forth, and also to feed your skimmer or other filter devices. Leave the in-tank flow to powerheads witch do not draw very much power and their flow is more random. So in this case, more does not equal better. Just my 2 cents

Hey, Garage, you realize that your signature should probably read WB5000

A lot depends on how many outlets you will be using for the return flow and also the diameter size (3/4", 1").
Right now I have a WB5000 plumbed external to a sump below the tank and it's manifolded to three 3/4" returns (main & frag tank). It provides good return flow since there is not too much head pressure involved but if I had to add an additional 3/4" outlet, then the WB5000 would be too weak for all four outlets.

Agreed. Maybe some more info would help.
How much head?
What size sump?
What size skimmer?
How many returns (size of pipe)?
I run a blueline HD40x and a 7000 in my sump (60x30x18) and I don't have any bubbles or rapids.
.....It's not only the size of sump, the number of baffles will also play a key role in how the flow dissipates.

See... I would tend to disagree with that for the most part but every situation and use is different. In my last system, My wb5000 fed...
- display tank which was an oceanic tech 90 with 2qty of 3/4 returns
- 10G display fuge with enough water that I ran it as a silent / siphon return
- and a 30G frag tank which also ran as a siphon return.
If I had all that directed into a single tank, even my 225 with dual 1" returns, it would be PLENTY. The qty of nozzles should not matter much as the goal of a proper return system is not to generate flow within the tank (unless it is designed specifically to do so) it is simply to circulate water from the sump to the tank and back so that your skimmer or other items can clean that water. But again, maybe this person is trying to do a seaswirl or similar, maybe even a closed loop so will see what he has to say as the situation and recommendation could change drastically at that point.
Another little hint that I dropped long ago and I MAY be incorrect on it, but after owning both, the 5000 and 7000 appeared identicle. Only difference was the impeller
So one could possible make it either 
But do not quote me on it as I did not try it. I have been meaning to put a 7000 magnet and impeller on my 5000 just to see how it goes but have not had the need to do so.

I run my WB5000 off a 120g main with two 3/4" Seaswirls. If the pump was only plumbed to the 2 Seaswirls, then yes, it would be too much flow coming out of just the 2 outlets. I have a 3rd 3/4" manifolded to a 66g frag tank and this makes the overall flow to feel like something in the vicinity of about 400 gph out of each outlet which is calm and not a strong stream. If I tried to add a 2nd 3/4" outlet to the 66g frag tank, then the overall flow falls below what I would like from each outlet IMO.
I also run a WB3000, 7000 & 10000 in different applications and like everyone has said, it's a quiet trouble free pump so far.

thanks for the quick reply guys
there will be no sea swirl
tank size is 60 x 36 x 24
sump is 48 x 20 x 18
as of now it will only be circulating water
but you never know with me i may join another system like a store display raceway
5000 and 7000 are the same price for me,so price is not an issue.
skimmer should pump 1322 gph
so the 5000 matches.
i was thinkin 5000 for hydro reasons .
im now using a pcx40 genx pump which i imagine is not as effeciant
Hydrologist i may take you up on that visit,where abouts are you in hamilton
thanks
