I had initially thought so until you said the particles are 'sand'. BUT - I would think that pointing the flow more upward would be helpful.This is interesting. Will positioning half the pumps lower pointing up be the solution?

I used to have this tank (or a very similar one) - the second weir is generally used the way it is designed - and doesnt need to be modified. There are also usually 2 returns (from my tank - I had a T off my return pump to pump into both of the returns that were provided with the tank plumbing.i could be wrong but it is almost like the weir on the right is used as a secondary overflow if the water level goes up. how much flow do you have through that hose? the thing i would wonder about increasing the gpm of the return is whether the pump would empty the sump and suck air when it is started? would your ATO misinterpret the drop in level and add too much water?
I do not see any reason for the right side to drain more slowly than the other one. To me it does not make sense. The water will only drain from the left and right as quickly as its being put into the tank by the return pump. Having both sides draining 'the same' will improve flow/oxygenation and filtration in your tank, IMHO. Did whoever set up your tank do something to the interior of th e overflow? I would try doing what you're doing with the pump, try removing the silicone from the right side (unless there is a reason its there) - and also being careful by removing some water before you remove it as it could result in more water in the sump.The overflow on the right drains VERY slowly compared to the left side. I could potentially remove that acrylic/silicone and increase the return pump…is the juice worth the squeeze? Seems like the main problem was my particles weren’t making it towards to surface. I think I should be good now with my new powerhead position.
Do I need to upgrade the return?
That’s silicone that got peeled off. The tiny particles…whatever. I ordered an internal diatom filter that will take care of it.I can only see the big pieces
Necking down a pressurized system with decrease volume and increase velocity. The issue I think initially is can the overflow keep up with a larger pump. If the new pump is adjustable you can adjust down if not. But a sub 1k per hour pump on a 250g tank isn't enough and may explain the particulates. If the pump is brand new at 1k per hour, age or wear on the impeller as well as head height further reduce this.I would aim for a 10x capable return pump and throttle back to your desired circulation. I also agree with making adjustments to your in tank flow to maybe help get the particulates moving a different way and not be trapped. I also could have totally missed the point and of so my apologies.A diatom filter should take care of your problem with particular issues however I did notice in your videos that you step your return plumbing down to what looks like 1” . When you step the pipes down you create a bottle neck there. If you are still considering a new return pump replace your smaller pipes so they are all the same size. Also go with a dc pump you can contr the outflow from them

I have no idea why he blocked off the tank. This older guy that used to work with aquariums did this. I was not involved with the tank at the time. It was 5 years ago.Saw a couple of the videos. So to summarize you want to get rid of the suspended particles? Change the flow inside the tank first but also drain things properly.
Why do you have the overflow blocked off? Is your tank not level or something?
Are those elbows in those drain pipes?

I just called the guy. He said if he remembers correctly it wasn’t leveled. But he wasn’t 100% sure.Saw a couple of the videos. So to summarize you want to get rid of the suspended particles? Change the flow inside the tank first but also drain things properly.

PS - to help peel the silicone away (not to cut the acrylic). Also just for discussion - what was the reason for the silicone in the first place?I would use s sharp razor knife
What happens if the reason that’s there is because the tank “wasn’t leveled”?I would use s sharp razor knife
The flow has a MAJOR difference. The one blocked comes off 80% less.Did you transport the tank to your place? What may have been not level before is unknown now. So whether or not you need that overflow blocked off slightly is also unknown. How’s the flow between the two overflows?
