I just Received my new Coralvue power yesterday from Aquacave in the past I have Vortechs so I am had expensive and now inexpensive power heads.
Aqua Cave had these on sale so I order the 3000 gph 24w pump regular price $45 it was on sale 20% off $36 for a 3000 gph power head how could I say no!
1st you need to know this thing is big! Dimensions: 6.5"x4.5" so you need room for them. they are duel shafts they also come with separate nozzle pieces. this is nice as you can adjust the flow in a couple directions. it's Magnet mount and goes though my 3/4 acrylic no issues. something the Vortechs have struggled with from time to time. also these are dead quite again something I can't always say about my vortechs. CoralVue claims 360 degrees rotation. I think that's pushing it but there is allot. the power cord is short maybe 5 or 6' there is no speed control so the pumps are either on or off! personally I wouldn't use these on a wave maker I just don't think they last. the flow over all is VG very gentle but it move a ton of water. maybe better then the vortechs. I am not saying in any way these are better we are comparing $40 vs $400 power heads so even if they burn out in a year still a good deal. I not saying these are for everybody but those on a budget might look at these I would love to compare these to the new Koralia 8 power head based on what I have seen I think I am ordering a couple more of these. they come in the fallowing 750GPH 1250 GPH single heads 1500 and 3000 GPH are duel head. Aqua cave still has them on sale not sure how much longer today or tomorrow I think code is HIGHSEAS20 http://www.aquacave.com/SearchResult...CategoryID=752
if not maybe we can talk Aqua Cave into becoming a sponsor I think Aqua Cave and CR would benefit! You know I always prefer to support sponsors as well. I would be happy to try to talk to them on the sites behalf. please pm with the latest sponsor prices and I will try to get Aqua Cave on CR!
I've used these for a while now. I have four of the sunsun, which is the same thing, just rebranded. They put out good wide flow. Yes, they are kinda large but they seem to work well. Wattage is 24w on the 3k flow and they are as quiet as the koralia. My only dislike is the cord is 5' so it doesn't reach very far, but for 20bux off ebay how can you complain : ) And they use a ceramic shaft. The stainless steel shaft was gen 1 and some had leaky voltage.
Does anyone know if any of our sponsors carry these?
I know that kee's has them. I've seen them on the shelves there several times. Good review labman! I have witnessed them in action on a few different tanks and I am impressed given the price you pay for them.
I agree that it's hard to compare these to a vortech being that they're designed differently, however, next to the Koralias I think it's a pretty even match. Having not owned the Coralvue PH's myself I can't make an accurate comparison but as for the koralias I can say that they do move quite a bit of water and it's a fairly wide flow. The nice part is the ability to adjust them directionally. That's just my two cents.
i have 2 1350gph cheaper ebay ones. they have the double and these are single. mine dont have magnets which i would probably get if/when i do it again but they work well. no noise at all, which is a complaint i hear others talking about with ph's. i will probably use these in various ways when i need them but i am about to put on a closed loop with a 1"scwd along with the return for movement.
