I built a salt mixer. Don't ask why. All other questions are welcome.

The cut list... well ehm, cut.

Fabrication took me a total of 9 minutes.

Fittings fitted.

Pump modified to suck air and mix. The pump sucks from the bottom of the container. I built the stand with 20mm Schedule 80 PVC.

Almost done. Added two small 6mm perspex tubes. One that my RODI outlet connects to (just makes filling easier), the other is a place for the airline tubing to connect to to make sure it's always above water line.

For the hose pipe when the salt is mixed, it is used to pump the new mix into the tank.

Dress rehearsal. I fixed the leak. It was my makeshift venturi. Nothing a little resin couldn't set right.

It worked well today. Then just connect the hose pipe, open the ball valve and let it fill the tank.

Cool, huh?

Oops, fogot to explain the idea behind it.

The outlet is pointed such that it causes a vortex. And we all know what happens with water when it runs in a circle. All the solids settles smack down in the middle. And guess what's in the middle? The pump inlet. So salt gets mixed in a jiffy because it gets sucked into the pump the whole time and goes through the impellor.

The second aspect of this contraption is the air inlet. Basically works like a skimmer. I like airating my new salt mixes for a while to help the pH settle and whatever else. So I open the air tap and let the pump suck in air. And how better to airate salt mix than with millions and millions of really fine bubbles.

And ofcourse the third convenience is the easy transfer of the new mix from the mixer to the tank with my garden hose idea thingamagick.

Naaw, I have built many things with PVC. Not least of all a bunk bed for my son.

I test everything myself when finished :) It carried my weight so 20KG's is nothing for it.

Very nice Gali, Nice to see you not wasting your weekends away
Thanks. Ya. I was pretty bored. My daughter is only two weeks old so she sleeps all the time and I can't exactly assist with breast feeding...:lol:

Plus my wife is happy that IO don't get irritated then agitated when doing water changes anymore :)

Shit, I don't remember the brand now. You can buy it from Builder's Warehouse. I suppose it's a common DIY type. It's a two part mixture.

No, I didn't use resin for the construction. Only to fit the little tube into the pump inlet. For perspex I use Methylene Choride. For PVC I use PVC weld. (This was the first time I tried the Bostic PVC Weld and quite happy with it :))

Awesome Gali, very clever idea :thumbup:

Just one thing...I was told that those green garden hoses leech out huge amounts of phosphate, apparently that could have been one of the main causes of my monstrous hair algae problem. I promptly removed all of the garden hose from my system, I was using it to feed my frag tank. Just thought I would let you know, not sure if it is true or not.

Well hang me up and spank me. The hose will promptly dissapear from my setup too. Thanks for the heads up. I have always been using them for water changes.

It might be ok for an occasional water change but I was running mine 24/7. If there is any truth to it then rather not take the chance.

You could always leave it there and run some tests for us over a couple of months :whistling:

Haha.. Thanks Punk. But this is hardly an essential piece of equipment. I would normall spend my evenings playing with my son but he's visiting his grans. So like I said, I was bored.

Plus, if you had to buy all this stuff it would work out quite expensive I think. I had almost everything lying around.
