I like to build the Geoff's skimmer but I have a mag5 instead of the mag7. How will this work,or not on the skimmer?
this is actually why i went with the rubber cap. it does not leak if tightened properly. i have tried knock out closet flanges, but they keep leaking at the knock out area. some people have had luck with these so it may be manufacturer difference problem. you can use a regular cap, but you will need to find a way to hold the skimmer upright. those caps are dommed.Little Luey said:Ok, I am looking to build the simplified skimmer and I have a few questions:
1. Instead of the 4" quickcap, can I use a solid end cap? Is the quickcap for maintenance? I am afraid it will leak.
sounds like you have schedule 26 PVC. i was using schedule 40 for everything. i am sure schedule 26 is strong enough for anything you will be pushing through the skimmer. i would use schedule 40 though if you can find it. this is what most of the places carry. it is just a bit easier to work with.Little Luey said:2. In my area there is only black PVC, is very thick, the white PVC is so thin it makes me nerveous to use it, I can deform the "T" by twisting it. Is this ok?
yes i used those two reducers. the skimmer can be as tall or as short as you need it to be.Little Luey said:3. How do you make the top of it? Looks like a reducer from 4" to 3" then anotherone from 3" to 1.5" maybe? How tall does this need to be?
i would not recommend doing this with the pumps you have listed. you need all the back pressure you can get for the venturi. if you split the outlet than all of the water will want to take the easy road up to the return. those pumps are not very pressure rated so if you were to equalize the two you would seriously hinder the water to each.Little Luey said:4. I am wondering is I could have the return pump split to feed the skimmer, I currently have a Quietone 4000 (1000gph) and a Quietone 5000(1300 gph)
that is exactly how i had it set up on the mantle it would drain directly into the tank. i had a heating/cooling area on the output, but for all intents and purposes it drained directly back into the display.Little Luey said:5. What if I want the skimmer to drain in to the tank?
