Wayne's 90 Gallon Build

[newbie2]

Nice build so far! Its making me itch to switch one of my freshwater 90's over to salt! So many options and gadgets, and then there's the livestock choices!

Alrighty! Well I added 2" of pvc to the bottom of my skimmer stand and now have it standing in about 7"-7.5" of water and it is has stopped overflowing and is producing a wet skimate! Problem solved!





I picked up some Cheato the other day and threw it in my refugium as well and while doing so, I noticed some pods in the refuge and in the DT. Life!! Score!







I also found a hitchhiker coral.. It is really tiny and im assuming bleached out if not, dead! Looks like some sort of Acan? I'm new at this so I am not really sure..



Thought I would throw in a shot of the QT tank as well for good measure.. Still empty sadly, not much longer though!!



All in all, still waiting on things to show up in the mail.

Small update:

The tank is doing awesome, it has cycled and I should be getting some fish to go into the QT tank within the next week or so. FINALLY!
Sorry for poor quality pics, lost camera charger cord so these are shots from my iPhone.



One interesting thing that has happened is the refugium has exploded with diatoms. I am assuming this means it is doing its job because the DT is still crystal clear and looking good other than some hair algae here and there. I've heard that the diatom bloom is natural in a new system so I am not worried. The cheato is also growing like mad!! I had to harvest a football sized piece and I have still got a large amount in there! Basically just waiting for some algae growth in the DT so I can get a CUC.



I have been manually dosing vinegar to promote bacteria growth as well and the now that it is tuned in, the skimmer is pulling out some really gunky nog. I had heard about how bad skimmate smells but now that I have smelled it myself, I truly understand. It is probably the worst thing I have ever smelled in my life!





I also plumbed in two Phosban 150 reactors (one for GFO & one for Carbon), they are fed off a manifold from the return pump and the effluent from these reactors goes into the return section. So far so good!

Hey,

Awesome build thread, great documentation. There is only one thing that I noticed that you might want to look into.

From what I understand ''T''n off the return with a gate and restricting flow adds stress on your return, which shorts life. If that's something you can deal with. Awesome.

Suggestion - From your Herbie, and your Emergency. Plumb your Emergency drain into your Fuge. The amount of water running through your fuge can be controlled directing from the gate valve of your main drain line.

Otherwise. Freaken awesome. can't wait to see the tank/fish/coral updates!!

I see what you are saying but my education tells me that a recirc on the outlet of the return pump into the refugium actually creates less backpressure on the pump and thus will actually prolong the life of the pump. If I had a gate valve throttling the flow directly on the outlet of the pump you would be correct, but the tee'd off line acting as slow flowing recirc line is a good thing! This is actually used in industry to prolong $$$ pump life.

Everything is working just peachy for me! So I am happy so far! Thanks for the input

Well I guess you learn something new everyday, I was under the general impression any restriction of flow would cause the back pressure on your pump. That being said it could be because of the 12 hour night shift and being up for 30 but I can't wrap my head around the physics behind it and how it doesn't create it care to explain?

Looking great Wayne, I'm jealous your stand has doors. I have yet to build mine.
Updated fish wish list?

For the sake of me explaining this I am making up some numbers..

Pressure= Force/Area
Force= Mass x Acceleration

Lets say for 1kg of water accelerates at 2m/s2.
Force= 1kg x 2m/s2
Force= 2kgm/s2= 2N

For now lets say the area of a pipe with no recirc line is 2m2

therefore, Pressure= 2N/2m2 = 1N/m2 or 1 kPa

Now lets do the same math with a recirc line, which would actually have a greater area then a pipe without it.

1kg of water accelerates at 2m/s2 again
therefore Force= 2N

This time the area will be 3m2 because we have more piping for the recirc.

therefore, Pressure= 2N/3m2 = 0.666N/m2 or 0.666 kPa

The extra area of pipe for a recirc line creates less back pressure on the pump as proven. This is such even with the valve restricting flow from the recirc line as there is still more area from the pump to that recirc valve than there would be from the pump up to an equal point in the line with no tee'd off recirc.

My explaination might be a little confusing but it works out!
