Brand New 8 gallon bio cube

[Why-Me]

There's a slip topside of bulkheads in the overflow box, those won't get any glue or anything.
Then there's slip on the bottom of those overflow bulkheads and there's slip going into the return bulkheads.
The only threads are inside the tank, bulkhead and locline.

Daddy said that I am looking particularly lovely today, see pick attached!

Where are the slip portions of the bulkheads? For inside the overflow box?

Here's a shot showing the only threaded parts of the entire build and the slip on the backside of the return bulkheads.

Looks good, I'd definitely use transition cement as mentioned earlier (Although I used regular pvc cement for my abs fittings originally and they held up for the few years the tank was up anyway) for the slip but you already addressed my one concern by saying you weren't going to glue the slip fittings inside the overflow box :)

If those are the only screw in connections, I wouldn't put anything on the threads. That is all inside the tank.

@crusso1993 so this article says not to mix sch 40/80 fittings? Can you mix for the total build?

It is okay to mix and match slip x slip fittings but not threaded fittings. The OD of schedule 40 and 80 is the same with the difference in wall thickness coming from the ID.

Very interesting that Lasco and Spears have two incredibly different opinions on what's okay for PVC threaded fittings...



As @Fin Mentioned above, lots of people mix and match sch80 fittings with 40 pipe. I think the key message here is certain fittings can not be mixed and matched with each other (Think Schedule 40 Male threaded into schedule 80 female threaded fittings).



Bulk reef supply has a decent sch80 supply but a horrible sch40 supply. Lots of other places to order schedule 40 fittings and pipe. You should post a list of everything you think you might need and the quantity of each and I'm sure we can come up with a solid supplier or two. I've used a few different suppliers over the years and I'm still trying new ones except for coloured schedule 40 pipe and regular fittings. I won't order from anyone other than Formufit.

Oh and I might have missed it, but what wouldn't match if he got colored PVC?

I cannot say for certain but that Spears video looks to have been made quite some time ago. I'd recommend checking with Spears to see if using teflon tape is still acceptable to them. However, even if it were, I still would never use it.

Yeah I'm not sure either and its certainly something I won't use again myself.

The Spears video was published March 15, 2012, so not exactly ancient. The key to the whole issue is to simply not over-tighten the fitting, no matter what you use, IMHO.

Trip to lfs was good. Andrew got a porcelain crab. Prices there are MUCH higher. Yasha goby 79.99.

Things in our area are very pricey. We need more competition.

Wanna see him? He's acclimating.

Wanna see him? He's acclimating.

YES!

 

[JoshH]

ABSOLUTELY!

 

[Katrina71]

YES!

Just for you. He's white with blue spots.

 

[Katrina71]

Andrew is a crab whisperer. He's gonna put him on the nem by hand. Fingers crossed.

 

[Katrina71]

He's pretty small.

 

[NY_Caveman]

Beautiful!

@najer there was a baby scopas that looked thin today. I wanted her. If the new tank was done, she'd have gotten me arrested. I just wanted to feed her!

 

[Katrina71]

@sfin52 you need a crab for yours now.
