Rare earth magnets

Are they ok inside the reef? Like if I wanted to glue some to my powerheads and then make a magnet mount.

Any issues there?

Thanks!

 

I dont see why not. Maybe you can seal them in some acrylic or something?

 

Like an acrylic paint?

 

No, more like casting/coating resin...we've coated magnets in resin in the past for keeping SH feeding stations in place.

Do be mindful that your PH may impart vibration into the tank panel.

 

Is this something that can be found in hardware stores?

What concerns are there with vibrations? I can think of some, but I don't know how much of an impact it would have.

Backstory, I have 2 maxis w/ eco mods and I hate suction cups. I woke up this morning to one sitting on a rock. suction cups

 

I've had a P. volitans that didn't settle down in a new system, and traced it down to vibration. Once the vibe was removed, the fish was fine. Think about how you'd feel if the walls of your house constantly vibrated.

I agree...suction cups often don't work well. We build closed-loops into our systems, and are much happier with the results. Of course, that's easy in a new system...

 

How do you build your closed loops? That's something I want to do on my next build down the road.

 

hmmmmmmm, I see your point. What if, (thinking...... might be here for a while) there was some sort of rubber gasket that would reduce vibrations into the glass. I'm no vibrations expert and just looking for something/anything better than suction cups.

closed loops? I'm a newb, so I don't know what this mean. :-[

 

A closed-loop (CL) is a way to add additional flow to your tank without using PH's. It is a completely closed circuit (no sump) that entails adding a drain (I use a spa screen in the tank wall) which is connected directly to the intake of a secondary pump. The returns for this pump can be added anywhere a hole/bulkhead can be put in the tank, and you can split the return to have multiple areas of flow.

I have used anywhere from two to four returns on our systems, and I generally run them thru a SCWD or Ocean's Motion alternator.

Here's how a couple of our tanks are setup:

48" 100 gal (this one has a "static"/laminar CL):



The green pump in the back is the CL pump:



Here's the schematic for our 210:

and now I'm drooling! That is a fancy setup!! Very well done.

Thank you for the fantastic explanation as well.
