MY 75 Gallon RR project and soon to be "former setup" DIAL UP BEWARE!

83078Overflow_modification.jpg

I used a dremel (that I haven't returned yet...LOL....sorry Fred! Almost done with it!) with a conical bit. This picture is pretty bad, my hand was shaky cause I just got done halfway.


83078mega_flow_modification.jpg

Here's a better shot. I might keep on going until I feel like the holes are wide enough. I might even make them taller. Hope this accomodates for all the flow.


83078hood_back_with_fan_install.jpg

I also play with my hood back and cut some holes for the fan. I'm gonna go two fans blowing in from behind the halides, and two sucking upward out (heat rises....no?!?), this way, I can turn on the top fans if the water temperature gets way too hot, even without the halides on...

Megaflow finally finished and ready for another re-run tomorrow. Let's see if she works! Post more until then..........
 
it does look good :) are u going to make the ones on the bottom wider 2?
when i first set up my tank the water was going in through the teeth real fast i had no durso's in there just the 2 bulk heads open & the water stoped about 3/4 of the way up, so i dint have to make the teeth wider but i was ready with my dremmel.

here are a couple of pics to give u an idea.

Steve, looks like your getting no surface skimming, though (water level ABOVE the teeth...or am I wrong?

Ideally, the water level should not extend above the teeth. This would provide max skimming of surface film.

Nice pics, though! :)
 
i guess because its so much turn over the surface is allways clean
i know it sounds weird but it skims the top of the water
u know what they say if it aint broke dont fix it
 
You know it!
Looks sweeeeeet to me. No film...No problem :)

Don't touch it. ;)

btw...I like your acrylic brace... I gotta keep that in mind.

yeap it works good i also have one that goes on top of the overflows so snails dont make their way in & over.
 
I'll be adding more slots when I get home tonight, to go around the Megaflow. The slots look like they will handle more flow, if that's the case, I might keep the Iwaki 40, but since I now have an Iwaki 20, I might use that as a closed loop pump, I don't know yet. I'll also be enlarging the slots in the bottom as well, just to make sure I get adequate water flow........we'll see when I get home, Thanks for all the info/support!
 
hey merv i got my pump to haldle the 1200gph with out a problem with only the 1 inch drain and without moding the overflow i just got rid of the durso and bam instant flow look great also now i'm thinking or using both as drains 1 inch and 3/4 inch and maybe get a bigger pump
 
IME when u plum a tank with the right pump & flow u can get away with out using dorsos but it's a guessing game, it depends on the tank,elbows,head loss,overflow teeth & bulkhead size to handle the flow & if u get it right u get zero bubbles in ur sump,
reeftreasures when i had my 125 i had a mag 24 on it & after i did a head loss count i figure i was getting around 1500 GPH, well someone pointed out to me that i was getting a lot less because the they saw a picture of my set up & noticed i was using 3/4 inch pipe to return the flow back to the tank, i was like yeah right well i replumed that pump with 1 1/4 pipe came up over the back & my overflows coulnt keep up with the amount of flow, that sold me on using the right PVC size for the right pump.
if u want to use the 3/4 inch as a drain put a 1 inch adapter after the 3/4 & run 1 inch all the way to ur sump it works great.
how is ur pump set up?

This is an awsome thread...keep this one going I'm learning alot about how I'll let up my next tank based on this threads information!
 
Quick question ~ you guys who use PVC pipes to run your tanks, do you attach the pipes with the same 2 part adhesive stuff plumbers use? or is there some more aquarium friendly PVC adhesive I should know about?
 
from my understanding... the clear cleaner is the same as the purple primer....only clear so you only actually need the two parts. I'm just using the cleaner and solvent. Joints are tight, strong and not all ugly with purple all over. I was told the purple dye was an aid to the plumbers to easily confirm they had primed the joint. The main ingredient of the cleaner/primer is Acetone.You could actually use acetone if you wanted but you have to go sparingly. Straight Acetone has a tendency to over soften the PVC. I got all this information from a professional pipefitter/plumber, so I belive it to be reliable.
 
Pump should be in as we speak, I'm getting it delivered to my girl's workplace.....Tonight, I'll run my system with the Iwaki 40 first and see how that works with the enlarged megaflow slots, then I'll test run the Iwaki 20 and see how that works. I'll probably take a few pics later and post them up tomorrow since I won't be home until 11:30 pm'ish tonight. Keep you guys updated!

Rich, as far as your question about the Concept1, 2 and 3:
