2262 and a 75gallon

[Robotlove]

I don't know how well a slot along the length of the spraybar will work unless it was tapered.

We built a 70" long spray bar for our 6 foot tank using 1/2" CPVC and drilled a series of holes along the length and the hole size was largest at the end of the run and smallest at the beginning of the run (closest to the output hose) in order to get an equal output at each hole. You will need to make up some kind of PVC adapter though to connect it to the Eheim 5/8" output hose.

I'd have to do a search to see if I posted on the forum though if you are interested in how we did it.

Do you think tapered even at a total length of 12-15inches?
Thought was to put in against the side of the tank not the back.
What’s the max size you’d make holes? 10 half inch holes on a 15in spray bar?

I've never tried a tapered slot so that would be an experiment you need to try but don't know if it would be worth it.

I think 1/2" diameter holes would be too big. We used a combination of 1/8", 5/32" and 3/16" on the 70" long spray bar.

Before changing the existing holes or making a new PVC/CPVC spray bar, why not just set it up normally on the short end of the tank and see how it works? If you find the flow is too strong, you can make your own spray bar and play around with the hole size until you're satisfied.

Deeda.....trial and error gets pricey ??

but I agree, I’ll just have to test it all out.
You don’t see an issue though with the filter in a 75?

The slot wouldn't be something I would try, I think the flow would be not equal down the length of the slot. For me, the return does more than just dump water back into the tank. It creates flow patterns that help keep food and waste suspended in the water until the intake can suck them in. When making a spray bar start with small holes. Holes can always be made bigger but very hard to make smaller. I doubt that you would require anything close to 1/4", probably more like 1/8 to 3/16 but like I said start small. I still say splitting the return is the best bet. You can get Y's in many different sizes and I have also used T's from the local hardware store. Later

Im not following you on why adding more filter capacity here is a “win win”.
The 2262 has a 18 liter media capacity. It’s literally the largest canister filter on the market. With a 950gph pump.

I have never seen a problem with more biological media available. I dont understand the aversion to it. Bacteria is going to occupy all the places where flow brings amonia and nitrite. Extra cycled media isnt a bad thing. I get that in your situation you dont need it but I thought the idea of dropping the flow was in deed a good one with other uses. The multiple outlets is another good option to help disperse the flow.

I wanted to leave flow and current patterns up to the eco tech mp10. Having flow rate uninterrupted but slowing down the velocity of the water entering the tank, is the goal.
Well that and one filter that can filtrate 7-9 times per hour.
