The Miracle Tank

[Katrina71]

Spray bars work great if u dont mind the view. Lemme know when ur ready to start picking out zoas for an island or whatever. @thejuice24 and I are gonna start prying his wife into letting me slide over for a frag fest saw marathon. No rush, and tbh I dont even know if u want zoas in there?

Lmk

You pick. It makes it more special.

Good Morning.

Love seeing the progress happening in this thread.

For the first time in months (and more like a year) the tank is looking like a tank again and not a glass coffin of coral death.

Typical. I gotta pick what u order for dinner too then?

 

[RichtheReefer21]

:p


At least gimme some colors... throw me a bone here..

So typically you install a check valve on your return line as close to the pump as possible and when the flow is shut off, the check valve closes and it stops the back flow. HOWEVER, check valves are notoriously unreliable at sealing properly and preventing flow from making its way back to the sump.

Melves Reef came up with sort of a backwards check valve setup that Fin has implemented. In this setup the check valve is installed backwards, above the return height. When the return is running it presses water up against the check valve keeping it closed. The second you turn the return pump off, the pressure drop allows the check valve to open and this lets air into the return breaking the siphon and preventing water from draining back into the sump.

The method I use is a little simpler in that I have my return line and instead of a 90° elbow to tie the return line into the retun bulkhead, I will use a T. The top of the T has a slip to thread reducer to reduce the top of the return T down to 1/4". From the top of the T coming out of the reducer I'll have a threaded elbow to RODI fitting. From there it's a simple straight RODI line with a 1/4" valve and then another 90° elbow to bring the line down into the overflow. Once the return is up and running water will flow out of this line and back into the overflow, you can tune the flow to almost a trickle and when you turn the return off, it will instantly allow air into the line breaking the siphon. Here's a very crude drawing of how it's setup.....

Both of these methods are essentially just siphon breaks to prevent excessive back flow into the sump from the Display. You can also drill a hole into your return line itself however these need frequent attention and can be tricky to get right as you need the proper size hole to let enough air in to break the siphon but you don't want too much of a hole that you're letting too much flow out of the hole. Hense the route I took, which takes a 1/4" hole in the line and let's you easily adjust it to match the size you actually need to break the siphon without having to drill multiple holes.

My overflow is completely covered with the one-piece magnetic wier. I couldn't use that method without drilling a hole in the top, which I can't do because the top is very close to the rear Euro-brace. I definitely wouldn't want to block any opening in the wier. I think my application is the best for my system. Just depends on what you have to work with.

I did find white locline. @najer I'd love a spraybar on each side of the weir with 3 RFGs. That would be sweet. You know I've been thinking about that since day one.

Keep in mind that it takes a bit of flow to make those RFGs work right. I think that six of them on a spray bar in a 90 would be excessive and you might not get the result you are considering. One on each side should be sufficient. With DIY spraybars, you have to be careful of the angle of the holes you drill. You might end up with 10 spraying where you want them and one spraying up into your lights. Ask me how I know. :P

:p

This reminds me of my wife going out to pick up some crappy fast food for dinner. She asks me what I want and I say it doesn't really matter, chicken or burgers, whichever you prefer. Of course, she then says, "Which one??!!!" She can't narrow it down out of two choices. :-)

Well, I missed the early morning shift. I was at the grocery store. We can now buy four packs of toilet paper, but only two packs of hamburger meat. :(

Without one you might not need the other! ;Blackeye Silver lining?

This whole situation is out of control.
Numbers are completely skewed. Tell me how there has been 0 flu or pneumonia deaths the last 2 months. I have family working in hospitals and medical fields and the hospitals are getting a bunch of money for each covid death. If u cough they will claim u had covid so they get the money

good point. I have a whole new world to explore with this tank

 

[najer]

The tank is sulking, well mostly, there are odd signs of joy, if anyone has Murphy visiting a bit please can you not aim him at @Raege or myself?! ;)

 

[Katrina71]

Send him my way. It's ok.

 

[najer]

So you want Murphy at your place whilst you plump the miracle, you're more weird than I thought! ;)

The CDC needs to parse the numbers but as of now it's hard to with everything going on.
This isn't fake or made up, my cousin is a dr in MN, my aunt works at Mayo in MN and I have a family member in ohio with covid in critical condition right now.
Numbers are just numbers, why would anyone deny the fact there's a really bad virus going around and not want to stay safe because of skewed numbers? (That's like arguing with a cop that you were only speeding 20 over instead of the 23 over he claims he clocked you at.)
At this point if people wanna go out and risk it that's their choice and I'm done feeling bad for those that may contract it whom feel this is faked or made up. Darwin Award winners entered here!!
But I do feel bad for those trying to stay as safe as possible and the people who go out carelessly endangering their lives.
And that whole claiming extras for more money due to covid is just a certain side's political talking point right now and that's all it is.
Also the hospitals and clinics aren't accepting most normal issues that go away at home, they are doing facetime appointments to not risk infecting those who have no covid symptoms!
So most people in the clinics or hospitals who are coughing probably have covid or are there for covid symptoms.
Rant Over I'm outta here, see y'all later!

Spraybar back in, the front holes have holes drilled at approx 90 degrees to shoot flow down the back of the scape, every other hole to the front, I have a vectra M1 for flow ramped down, I figure using rfgs can let me push the flow harder!
I also put this together wrong after a clean and nearly washed my lights! ;)

There was a long post about my spraybar, not typing all that again!

That was my immediate thought and why I only bought two packages of toilet paper instead of four. :)

I am in agreement with you. I believe that the virus is real, but there is a lot going on behind the scenes that we will not hear about. I just typed a long response but deleted it. We aren't supposed to discuss this on R2R. I do question how is it being handled and who is calling the shots. Newly discovered medical treatments can now be patented. I know that whoever ends up with the patent for the vaccine is going to make an insane amount of money.

When I lost my job last year we mothballed 12 labs and a research small scale production facility, I wish I could click my fingers and get those functional again!

good morning all.. :)
