Did you get that rock from kevins latest shipment? If so I'm experiencing the same thing. Pretty well normal with uncured rock like this. It'll just take longer with all the extra nutrients, keep at er and that algae will be gone soon enough.

Yeah it was from Kevins last shipment. No idea how the algae keeps getting longer when the lights are off... but it'll go away soon. Just did a small 15% water change as well.

So, just wondering about that overflow backup drain. Would this system work here? Or would the multiple bends not allow flow to start when needed? All made of 1" pvc. top has teeth cut into it.

I'm interested in this setup because the new 187 i'm getting only has one hole drilled in the overflow as well.

I don't think you're emergency would work. You could drill the back of the tank though to make it work.

No, that won't work. You can't have the highest point above the surface or the flow won't start on its own.

Yeah thats what I thought. I just hate drilling glass... and paying for it is even worse lol. Any other ideas?

once you get your "drillin legs" its not all that bad.......after you've drilled one or two, its all the same:wink::mrgreen:
