Miracles 144/125 Rimless

[Floyd R Turbo]

Been a while since I updated this thread. I have a backlog of pictures and videos to post and I'll get to them when I can. It is rather satisfying, because in the month since I posted last the L2 is growing consistently and today I tested the water pulled from the tank before cleaning the screen and N=0 on Salifert and P=0.00 on Hanna Phosphate Checker. The water in this tank has only tested 0.00 on P 2 other times since I got the checker - one week after putting the old scrubber back on after setting the tank up again in December, and one other time but I can't recall when that was.

Well here's a very long overdue update covering several cleanings since the last set of videos posted on 7/8....

Tested water today - cleaned screen 5 days ago

P=0.03
N~0.5

So there is a slight rise. Going to continue testing at mid-week and end of week before cleaning.

You have the screen way up into the tube feeding water. I only have a small amount into the tube. Does it make a difference how much screen goes up in the tube?

I hope I'm explaining that good enough.

Smitty - shove it all the way in, then it don't flop about too much.

[Floyd R Turbo]

smitty, it doesn't matter how you do it, if you do it like you are (I did it that way on my larger old scrubber) then you just support it by the edges of the screen. If you only use one tie, you have to put it in the middle and then the screen is kept "square" by the top of the screen holding against the inside of the top of the slot pipe, that's all. IMO either way is fine and doesn't affect flow, but I have noticed that the in-tube screen tends to be a home for crustaceans. If you are feeding via overflow, I would choose the 2-tie method like you are using for the reason that if something were to make it down the overflow and into the pipe, it might snag on the screen if it were inserted all the way into the pipe, whereas if it is not, then water pressure would push it to the end of the slot pipe.

Obviously Floyd is vastly more experienced than me in this. I find that shoving the screen all the way in, held semi tight with 3 ties allows for adjustment. When the screen grows heavy green it can buckle. Subtle movement of the ties can redistribute even flow to both sides of the screen ( my screen is 13 inch wide though ). I see you crustacean point Floyd. I got extra folded screen in mine to even out flow and not had and problem yet though but saying that, mine is not overflow fed directly.

Do you have a pic of this folded screen thing? Didn't understand that the first time I saw you mention that

A couple videos that I took yesterday, the first one is a overall tour of the tank and system



Second is a beginning-to-end cleaning video

Cleaning after 10 days since last cleaning. This is still running a Rev 1 L2.
