I was once a huge fan....

Used to love the Hydor Koralia pumps and the new evolutions seemed just freaking awesome when I got them. The freaking screen on one of my bigger evo pumps broke off and the pump seemed to be pulling water into the front of it! Seeing this right after looking at Bill’s MP40 on his big tank and then helping someone else hook up a MP40 on his. Really thinking I am done playing with these little made in china POS and ready to get something a lot better.(not that I have the $ just laying around, but man these dinky little toys are ticking me off)

I have three of them still working fine, so they aren’t all bad, at least so far. They only came out what 8-9 months ago?

well, my 2 are fine. as are the 4 older models.

Jon - it’s a known bug for the evo pumps on a controller.

You just have to take it off the wavemaker for a little while and turn it to “on” and remind it which way it’s supposed to run.

I’ve never personally had the issue but remember reading about it when they first came out.

They are supposed to work with wave makers fine, but obviously not all of them do forever. Solid on all the time is just crappy.

Only for a little while. I think it was only like a couple hours.

I sent them an e-mail about it and also reminded them about the other parts they were going to send me a couple months ago for some of there older pumps. Hopefully I hear back from them soon. :frowning: Last thing my tank needs is to become low flow.

Get a five gallon bucket, some 1 1/4 inch pipe and fittings and bulkhead and build a Carlson Surge Devise. and then sit back and enjoy the regular WHOOSHING sound. but you better set your water level a little lower to hande the surge. all it takes is a maxijet pump to feed it. or larger if you want to flush more frequently.

like Atlantis uses with barrels on some of its display tanks. Or how Pocono Coral farms feeds their frag tanks…

I thought it was how they fed their tanks… I thought you said they went out of biz.
I am actually thinking of setting up a surge device soon as I have never done one. Just a fun DIYS project I don’t have hands on experience with yet.

Pocono does use them as overflows cascading down fom the high tank to the low tanks. one return pump fillsthe upper tank and they surge about 20 gallons to the next tank. so 4 cascding frag tanks, one return pump and no power heads . pretty good. i guess they are still in business. website is still up and frags for sale.
