flow for a large tank 300 gallon build HELP and advice needed trying to eliminate/reduce wave makers

[1000rrstunna]

ok guys and girls i just got my new tank in a 84x36x25 glass cages

it has :
3 - 1.5" drains
4 - 1" return bulkheads
1- 2" closed loop suction outlet
2 pcs 1" seaswirls
3x mp40
2xmp60
4 xf gyres and a wave engine

I have purchased 1" locline segments and 4x 1" vca random flow generators

I have 2 new in box vectra L2
one new in box varios 10

was considering using the vecras for the return pump/manifold and the varios for the closed loop.

I feel like I am over complicating things but this is a 10 year anniversary build and hopefully my last upgrade for a long time.

I was considering taking the 1" pipe from one bulkhead and going straight down under the sand and making a string of 3/4" nozzles to blow bottom to top and all over while running the other 3 nozzles off the two vectras. i will take 1.25" pipe straight to the 1" bulkheads as to keep restriction to a minimum. looking for suggestions on how to utilize what i have to the most of my ability.

I can also sell vectras and get another varios 10 or vice versa. i will post an amateur sketch of the closed loop idea below

thanks
Glenn

Terrible drawing of idea in my head.

Have you considered Sea Sweeps.
I run 2 with Tunze 6255 powerheads. My system is 60×30×22.
The 6255' put out some serious flow. Only 2 cords in the system and they run through the sweeps.

I have but I have a closed loop in the back panel I need to use. I have two seaswirl considering doing this with them at about 12” down with random flow generators.

The closed loop hole was poor as well I should have went with it on the right side… it’s really my nemesis right now with drains. They work like this but are ugly and I really don’t want flat runs… or am I overthinking it.

Just a suggestion, I would run hard PVC to the wall with 90 elbow. Then connect your flex PVC to those so it looks more clean. I would support the 90 elbows at the wall (i.e. pipe strap or anything to hold pipe's weight). I think it's okay to have flat runs as long as it is supported. I put my gate valve closer to the sump, but that's just personal choice.

The flat runs don’t kill the gravity drain ? I always thought we want pitch.

If you just have a little (a few degrees) pitch, that is preferable so it doesn't trap any dead water in the secondary or emergency dray. For the main drain, water will be draining from the overflow box, so it will push any water in the flat run on the main drain. It will not kill gravity drain.

You inspired me to go play… with the Random parts I threw this together to see and I kinda agree that you are right… lol
Closed loop clearance also much improved 100%

Said Yolo and went at it… this was an awful tight fit and I’m gonna add unions by the sump but holy crap this was TOUGH my mistake with the close loop hole gave a large challenge but I think I’m good to go.

Any suggestions on uv plumbing now ? Was going to run it on a stand alone pump in skimmer chamber then into return is there a chance that the uv pump and that pump could outrun another ? Then how do I balance etc. this is complicated but I think I’m overthinking. I have a lifeguard 55 watt that says I want 2100 gph my tank volume is 300 gallons
