replacing overflow help

[dutchbro14]

i recently picked up a 90 gallon and its needed work to say the least. scraped off the coraline, redid the silicone, buffed out the scratches...but this damn overflow is an eye sore in the tank. calcium buildup that still wont come off after 2 days and a wierd design are also pushing me toward wanting to replace it. is it possible? what site sells internal overflows?

in this pic you can see how to water flows over the lip into this funky cave slit area? found alot of gunk down there....took a fair amount of power washing and still couldnt remove all of it. is this common on other overflows? really just wanna rip this thing out.

Did you soak with vinegar prior? Should let it wash right off.

soaked it for 12 hours. it helped, but only a little. i even let it dry after an took an electric sander to it to no avail

use muriatic acid (diluted) and it will come right off

Those lower slits defeat the purpose of an overflow for surface skimming. Terrible design, I don't know why they keep making them!

I would remove the overflow completely, put in a coast to coast, plug the bottom holes and drill it for a bean overflow

theres alot of disadvantages i know, but does anyone know a place that sells top to bottom overflows? the coast to coast idea is intresting, but i think the glass was tempered after it was drilled.

How is that? I have these in my 125 and I think they are a good design. I get a lot of surface skimming from the top slits and the middle ones provide additional water flow. I don't see a down to this design.

I would not remove these are even worry about cleaning them. One thing I suggest is to glue rock to them to both hide them and cover up the coraline. Even if you did end up getting them clean they'd look like they do now in a few years anyway.

I seriously would just reuse it as is. No need to replace it at all. If you want to replace it then I would do as sleepy suggested and remove it. Plug the bottom holes and drill the back for a superior beananimal coast to coast overflow.
