I am just checking with you here for my understanding
... You want the baffles set a few inches higher then the optimal skimmer height? Is this just for extra water volume in the sump?? For extra stability?
So you will use a stand for the skimmer to get to the 9-10" (optimal operating height per Shawn on your already purchased skimmer)?
Not a bad idea to add extra water volume... As long as the sump will still handle the DT drainage and back siphon. Shoot, you paid for a 75g sump why not get all you can out of it.
With the stand for the skimmer and your new DT stand will that give you all the room you need for maintenance on the sump and skimmer??
Sorry didn't mean to come off as snappy......Rather hard to explain in text.....I tried explaining to Bob a bit my reasoning or rationale......I wouldn't go extremely crazy with making the baffles high.......Thinking being 2 reasons....1 the methods or what not that are out there are rather proven....We can always tweak and adjust, but lets keep it close to the "box" per say......
That said I don't see any reason to make the skimmer intake area 16".....Yes you can build a skimmer stand to get the skimmer into operating range......Then again you suck up "head space" inside the stand.....For what....Nothing really gained IMHO.....Ok so you make the skimmer baffle 16" tall.......Ok.....He has a plan to run 2,000gph through his sump.....Think about the water level in the return side......I've seen and done this exact thing and what happens is that the return pump will pump all the water out of the return section to the tank.....in the meantime the intake/skimmer is filling with water and watch the return section get sucked dry of water......as the water overflows the skimmer section the return pump slowly picks up the water, but will still suck it faster than the return section is being filled.......
With that said what the next course of action would be is to add water to the return section of the sump till the pump stops sucking it dry......Guess what you just did now.....Your running a good risk of overflowing the sump in the event of a power outage.......Trust me I've been there and went back and made the change and cut the baffles down.....Why most people don't know my sump is 21" high.....Equivalent to roughly 150 gallon filled......
Extra water volume is great, but what real volume are you gaining.....Not much at those heights.....He might even go so far as to throttling back the return pump to keep it from sucking the return area dry.....Then he's negating away from his original plan......I'm not saying my theory is totally correct, but I did make my baffles at 15" and cut them back to 10" after the fact.....
Again I'd suggest tops 13" on intake/skimmer section.......Still would need to adjust the height on the skimmer, but very minimal. Plus another thing to look at is the distance the water will fall from the top of the baffle to the water surface inside the sump.....Again another noise issue that can be negated with properly set baffles.....The fuge I don't see an issue with running at 16", but would still try to minimize the drop distance to the return section.....Again this IMO still doesn't warrant running water depth that deep, but as long as you have "head room" for any back siphoning you can go as deep as you choose.....
