Couldn't you just add a gate or ball valve?
You have 2 drain lines I would add a valve on one of them!kinda like the Herbie overflow
From what I've read the higher the water falls in your overflow box the noisier it gets.

I have a gate valve on the main drain, just under the tank
Problem I'm finding is, with the design of this overflow setup, the back box sits lower than the front, so the water falling through the weir teeth 'falls' down to the level of the 1-1/2" through-the-glass bulkheads. Unless you run the back box nearly full, you get water falling.

Gate valve see pic #4 on page 1
First few pics also show the difference in height between the front and back boxes

Looks good Greg, really like the cleanup process and attention to detail, very neat.

How many gph are you running to the display?
The emergency overflow pipe should be able to handle quite a bit, so i suggest bringing the water up as much as possible to the teeth, like 1/4" or even less.

On my old 120 running a Eheim 1262 full blast i had to have the main drain pipe closed about 95% with the gate valve on a 1" drain, so I don't see how a second emergency pipe can not take all the flow if something were to happen...

You have too much spare time on your hands my friend.....when you coming over to do my wiring? :mrgreen:

Wasn't spare time per se, I was laid off for 2 months.
LMK what wiring you want to do, if you're serious :biggrin:

Thanks Chris
As for the overflow - the emerg is a straight standpipe so it won't go into full siphon, and I'm not comfortable having a 1" pipe closer than 1" from the top. I'd rather hear a little trickle through the teeth than trickling on the floor :wink:

Acquired a bunch of new frags last night
Stay tuned for pics

Long overdue update

Bought some more fishies

A Coral Beauty and 6 Lyretail Anthias'
Still trying to get the anthias' to eat pellets, but the angel is good to go.
Hoping it will teach the anthias' about pellets, but not holding my breath
I've just recently started soaking pellets in frozen food ... any tips would be appreciated

Really, please help me get these anthias' eating anything other than frozen :smile:

Tank is doing well, still balancing PO4 with NO3. Nothing major

Transferred the remaining fish from the original tank that were stuffed into a 36g holding tank for 4 months ... poor guys
They all made it
Had to sell 1 though ...
Started off with a male Lubbok's a couple years ago, and added a female 1-1/2 years ago. They got along fubulously for the last year and a bit until the tank failed.
Once they were trapped in the 36g the little female decided to become a 'hell on wheels' male and drove my original male to the point of starvation with him hiding.
Thanks to Chris for taking the wrasse from hell, and good luck to you sir :surprise:

Thanks to Catalin for hooking me up with a few corals I lost while they were in a crappy backup tank

Yup, my camera skills suck
I will get better pics up soon as I think my camera can do it :wink:

A BIG thanks to Warren and the Illuminati crew for getting me into the next stage of corals
These are some of the most awesome corals I've ever seen, and hope to have them look as good in my tank as they do online.
Pays to have friends, and I can't thank you guys enough :biggrin:

I always got mine eating pellets by starting on frozen cyclopeeze(sp?) and when offering that id offer pellets for the other fish. I was using Omega One micro marine pellets. (At the time my clowns mouths were too small for the 1mm pellets so i kept the micro on hand and fed that daily.) Both the cyclop and pellets would blow around the tank and the fish would just start grbbing whatever went past, after a few days they stopped spitting out the pellets.
Never bothered offering frozen to the group of red fairy anthias i recently purchased. They went right onto 1mm pellets. Pigs....
The lyretail group i had learned to eat pellets really quick. Less then a week i want to say...

Tanks looking good Greg! Well corals... need fts! And some wavey coral like euphyllia ;)

Grow fuzzy sticks, grow!

Thanks Gina. I've been crushing 1mm pellets. Tonight I'm trying a soak in some fish oil and garlic. Then I mixed them into the frozen stuff I make.
Just waiting a few more minutes for it to soak really well.
Fingers crossed.
