Anyone know if/when larger sizes are coming? Would love to get a 300 g version of this once we have a house to put it in.
 
Here is a question for you guys. How are you guys pumping enough volume into the 120 gallon tanks to make good use of the 1200 gph rating of the overflow? I have run a few different pump configurations using the headloss calculator and most numbers have been 700 gph or less. Considering I bought the overflow kits and am restricted to the 3/4 inch return bulkheads and pipes. I noticed alot of you guys were using eheims but I'm guessing you must be seeing low numbers as well.
 
I use 1" bulkheads with 1" pipe and they are said to carry 600 gph each for a total of 1200gph for the overflow. I have a 1080gph external return pump and I had to trottle it down because two much water was going though my Refugium.


sjediets,

Thanks for the post about making the overflow and sump quite, that's what I'm looking at doing. I will have to read up on those threads.
 
I'm running a Reeflo Barracuda on my 120 and it's running wide open. The drains are able to handle it without any problem. So 1200gph definitely isn't the maximum...
 
are you using 2 of the holes for a closed loop? I still would love to do a closed loop. Would it still be a good idea to use a durso stand pipe though? I was thinking of placing a BH in the 2 returns and then a screw in strainer. I'd do the return over the back on a sea swirl then utilize another sea swirl for the closed loop. Just an idea. Hope that makes sense. =)
 
cstires, are you using the 3/4 inch returns that come with the overflow kits? And if so how did you plumb that monster?
 
I'll post some pictures, but I built a manifold out of 1" PVC, and have 6 loc-line exits on it. See below:

The two valves you see in the first picture are used to adjust the amount of air entering the durso's. This allows me to fine tune it to keep it quite. It's pulling air in from the garage also, to try and help my PH, although it currently isn't a problem, we've had our house closed up for a while now due to the heat and rain we've been having.

Just thought I would share what that was incase some where wondering.
 
Regarding the durso valves, you might consider replacing the tapped PVC caps with capped elbows -- I had problems with salt creep gradually clogging the John Guest valve. Having the valve at the end of an elbow shields it from spray and pretty much reduces clogging to zero.
 
hey guys got another idea for you. as you know the tech tanks come with 4 1inch hole in the overflow. i know you cant use the intake from the overflow as a closed loop intake, but what if you put a 90 on the to outside holes on the overflow and put a bulkhead with a straner on the sides of the overflow. you wouldnt then have the problem of overflowing the overflow bocks with the closed loop. you would just be pulling water from the sides of the overflow box and you wouldnt have to drill a hole in the tank.


ps- if this was to confusing i will be picking up my tech 120 in the morning i will try and post some pics of what i was attempting to say.:D
 
Problem is the overflow is made from glass with black acrylic wrapping it. You'd still need to drill the glass in the overflow.
 
i did not know that! i pick my tech 120 up later today so all i was going on is that the all glass overflow were plastic.

- and guys i had the chance to talk to the rep for all-glass the other day and i was told( i know alot of people have been told alot of different things) but all tech tanks built before nov of last year were built with ultra clear glass on all three sides. and all the tanks built post that were built with starfire front glass only with regular glass on the sides. so we will see i pick my 120 up later today so i will try and post some pics.
 
why cant they just make the damn things all with ultra clear glass!? its less money than starfire and better looking than regular glass? i hate the lack of consistency
 
MarineGirl a way I have seen done with tanks that have overflows is to run a pvc pipe down in the back of the tank with a skimmer on the end. Then use a threaded tee at the top of the for the pipe going down to the external pump. The return line is then plumbed in. You then fill the entire line with water and cap off. This allows you to take apart when needed. the water will siphen down to the pump when the pump is started and it does not go anywhere when the pump is shut down.
