Ahh, OK, Cool. makes sense :D

I have all my water go through the skimmer box first, before passing through the fuge & then the return pump. Just a thought.

Have read that skimmed water isnt allways best for fuge. Alot split their flow, like argan has. I have split flow as well. But, nothing in Fuge yet, need to build fuge V2.0 first.

I plan on underskimming quite a bit, so thats why i went with this plan.

and yes, the softner salt is for DIY rocks

Looking good, I tried DIY rock didn't come out as nice as yours looks

forgot to mention that batch didn't have the salt in it. will post those pics tommorow

put a salt batch in the sink This morning. I think i didn't use enough cement or make big enough pieces, cause it was very crumbly. pics soon when the salt dissoves.

the softner salt dissolved in about an hour, and looks like it worked pretty good. I just have to refine the recipe.

this one has four holes, by fluke they are equally spaced

gonna do another batch soon i hope

Sweet looking rock. I like the porosity you can get using conditioner salt. Are those little round balls perlite?
