Is it bad to prefilter before going into the skimmer?
Not “bad” but possibly less desirable not detrimental though. Also — instead of holding the prefilter up with PVC, I am going to glue it to the corner of the sump a couple of inches above water level. Uh hmmmm I dont know if thats a good idea? You want to have everything removable so when you perform maintenance it all comes apart easily. I dont want to appear dogmatic 😉 but I would try to implement the PVC stands, with eggcrate/ prefilter/driplate, its very inexpensive you can even use the common white in the sump. I really just want to force the water to flow through the prefilter material. Not forcing, solely by gravity. the water gets collected in this DP and then *drips* through evenly depending on your holes.As the drip holes are fairly even this disperses the water evenly through the PF Material.
