Ashurbarnipal's 80 gallon

I would think that you'd also need primer..?

Correct me if I'm wrong Cliff, but PVC needs to be primed then glued. When I built a drainage pipe for the pool I primed then glued and it still leaked, but its drainage so no big deal.

[Cliff]

You will not need primer unless you are using different types of PVC. For example, using PVC and CPVC, or scd 40 and scd 80 (regular and extra heavy) PVC. I think when you use CPVC or system 636 PVC (gas vent PVC) you have to use a primer.

I have yet to use a primer and have had no leaks. I also used PVC without any primer when I finished my basement and it passed inspection OK. I've also did not use a primer on the return lines on both my reef tanks and all is good

Thanks for the input on this. As a plumbing new, it's very appreciated.


Also, was talking to a fish guy locally and he brought up something I thought I should check. He said blue throat and niger triggerfish were potentially coral-safe. Liveaquaria seemed to think so with the Blue throat at least.


What I wonder is how true is this and how FISH safe are they? I mean, I'd love triggers, but not putting them in if they'd bother anthias basslets/dottybacks etc

Note: I'm not that seriously considering triggers, I just wondered

[Cliff]

From what I have read, the bluethroat trigger is indeed reef safe and will not outgrow youe tank. The niger trigger would outgrow your tank at some point. But that all based on what I have read. I have never kept any of those fish

Well, I just picked up the 55...though actually it may be larger than a 55, I dunno.

I'm wondering what sump config would allow for the most volume of water and in particular the most space for a refugium?


I kinda wanna do this: http://www.melevsreef.com/acrylics/sumps/f/sump_f.html

But the refugium space is lesser than I'd like.

[Cliff]

I suggest your first step would be to determine how much drain-back you would get from the main tank into the sump if the power goes out. Once you know that, you can determine the hight of your baffles to make sure your sump will hold the extra water.

That way, you will never have to worry if the power goes out

I've done that on both of my sumps and it works great

[Ashurbarnipal]

The hole is 3/4" wide and at the very top of the tank, right at where the waterline would be. I figure it'll drain at about 600 gph from that chart you posted.

[Cliff]

Is that the measurement of the hole in the glass, or the inside of the bulk head flange?

In my last post I was actually referring to the amount of extra water your sump will hold in the case of a power failure

[Ashurbarnipal]

Inside of the bulkhead flange. No idea about the hole itself. The bulkhead seems to be siliconed in.

Well, I ran the aquarium calculator dealie, and if it's right, about 5 gallons should drain when the pump stops
