300 gallon setup/sump build

  • We are currently upgrading MFK. thanks! -neo
Got the tank side of the returns mocked up. Already happy that i had chris move the bulkhead towads the middle of the tank.

Both nozzles at an even length from the tee.

I like this better just not sure how far i want the nizzle furthest from the overflow to extend from the tee.

This is witha 2 inch length of pipe (not two inches from the tee)

3inch length of pipe

4inch length

White pvc with be painted. Not sure the length of the loclines but i can always just unscrew them after its up and running to add/remove.

Another option is to extend both loclines rather than having the 90. This way no need for the pvc to extend.

I personally would like to keep as much of the plumbing away from the front viewing pane as possible. What if you turn the T sideways and then run one loc-line out the side towards the back and then the other out the bottom. It should keep the second loc-line about 4" further back away from the front pane. Again, that's just my preference, it will look good either way.

Also, for the fittings inside the tank, I recommend you not glue those. Worst that could happen is part or all of the return falls off in the tank and no harm done. I mention this because I know I ended up changing my returns inside the tank many times before settling on my current setup, and they might still change again.
 
To raise the tank and stand all together just use 2 car jacks.. no pain or break a tail bone while lifting off the floor. Like other mentioned screw down the 4x4 to the stand so it won't slide off. I only have the 4x4 on the full length of the stand and not the sides since my sump are almost the tank length. GL keep up the pics n Qs.. LoL

Thats a good idea. If the plumbing get to screwy i may do that.

That was the initial thought but will the polys coming up for air ad getting spooked i was worried that they would move arond the loc lines and potentially move them towards the top of the tank. I think im going to use the least amount of loc line hose as possible

I'll try it. But i think more would be visible that way it would further extend donw into the tank ? But will take a look.

Have the return lines almost done. Going to install the check valves on the sump side.
I forgot why i only got the fittings in black was either too cheap or he only had black flex pipe. Gonna spray paint them today.
I feel like i could get most of the plumbing done if the two gates were here. Smh

jvc66 jvc66 not sure if you knew this but i didnt when i did my first sump. After press fitting and getting everything lineed up the lines ensure that it will still be lined up after gluing. Using a dry erase marker so it looks neat afterwards

Got a question guys. I was thinking if i staggered the nozzles that it would cover more area of the substrate. Everything is glued except to the bulkhead.

Do you guys think this makes sense ? Would the return on the left somehow impede the overflow from caprturing gunk because its too close ?

Left side nozzle closer to overflow.

Right side nozzles further away from overflow.

I don't think you will have an issue. My return is between the overflow box and the wall. I can tell you that even with the strong current from the Hammerhead pump, floating food made its way into the overflow box. We went from floating food to exclusively feeding sinking food. With your ability to adjust the return nozzle, I don't think you will have any problems.

I know you already know this, but just make sure you've accounted for any back flow when the return pumps are off. Either breaking siphon, check valve, your sump can take on all the back flow given the depth if returns/drains or all of the above ;-)

Going to use both siphon breaks and checks
