Thanks a bunch! I do what I can. I am really happy I decided to take the tank down and re-do the plumbing and stand and everything. I'll be much happier with it in the long run.

I have corals in and growing nicely now, I guess its time for an update. I'll do that shortly.
Yes update, I was wandering where those were (coral).
EDIT:
Tank looks really swell! The w must have been goofing off when I hit it.

With the Herbie, have you noticed it fluctuating with the barometric pressure?
You have the best set up for Herb straight and vertical.

Did you do the siphon break you mentioned earlier on?

Your tanks looking really nice Sean.

If I could do it again I would raise the backup about a quarter inch so that it's very slightly higher, but it works very well as is.

The only thing that's difficult to quiet down is the weir with the new MP10, every time it goes from surge to wave it takes a couple of minutes before the water level in the inner box stabilizes and you stop getting that falling water noise over the weir.

Sure makes a check valve seem like a dumb idea.
Not an issue. Just add an elbow inside.
If that's too high or too long to fit...
Snug the elbow into a length of PVC, slice off at least half of the would be otherwise cemented joint.
If you have to run both ends in a power saw, make the 1st cut the longest for purchase on the 2nd cut.
Now, is the bulkhead slip on the inside or threaded?
If threaded, 1st screw on a conduit nut that fits before cutting length down
and don't cut as much off since the threads are tapered I believe.
Then when you remove the nut, it fixes the screwed up threads somewhat
and a couple wraps of Teflon tape will facilitate a more smooth task.

You should try lowering the MP10 to accommodate your weirs operation or noise.

Check valves are dumb. They foul so they fail.

Yeh if you can use a regular elbow it will allow more back up buffer
to the main drain if it's not a street elbow, though a street is plug n play ready
and you can remove some of the male end to tidy up and increase room if necessary.
A reg elbow in 1" would need about a 1-3/8" length of PVC for no cement
and no modifying of the elbow to fit.

Anyway your coral all look super. I be jealous bout now :)

You guys are funny :)
Nice work Sean, aside from the green guy
(Elf, Peter Pan, The Green Lantern, the list goes on…)
it really looks very professional! I need a skinny one
and don't care about evaporation really, other than making up for it in the tank.

These videos should be 1080p but the max it gives for an option is 360p for some reason
You're good. They always take a few minutes to go HD for some reason.
Haven't watched them yet...

Yeah it is quite a bit of flow. Sure works well though.

Yeah mp20s would be useful. I'd like an mp40 eventually for my 75 build but really something in between the 10 and 40 would be great.
You did not read that wrong or I did not leave a zero out :) MP 2

The thought crossed my mind you might have meant that but I figured it was a typo lol.

So how much flow are we talking here? like 350 gph?
Why not 250? MP 2.5's :thumbup: 3's do sound better though.
My bubble coral could not survive in my 5' long tank with more than
one MP40 thrusting a little above idle. 2 MP40's at the minimum thrust
was too much for it.

Well you could turn down the flow to 250 lol.

MP-3, that would catch on.

Was the glass/acrylic too thick to use mp10s?

I need to get me an MP40 for the 75 gallon lol.
Not too thick no, the pr of MP40's were basically free :biggrin::bln-wow:

With a MP10 yes but not on the 40's I had.
Those you can turn down to 1,000 gph each and that's just not enough for me.
Plus at 250 gph you'd be idling with no thrust, so a fixed prop
would be more money wise.
