Who rates skimmers

Like I already stated, it takes more experience to run higher flows through overflows properly, it's not for everyone and it's not necessarily better than lower flow. That article is for beginners, which you would have noticed if you read the title rather than immediately trying to find something to argue with. I would never tell a beginner to use 10x turnover just like I wouldn't tell one to use a herbie overflow either.

You quoted the article to back up your statement, I am arguing no more than you are.

I have always promoted low flow, and have used syphon systems for many years, I have never advocated a Durso, a Durso is for people that have incorrectly sized their drains.

Please refrain from accusing me of making this a personal issue.

Perhaps you could read things properly before making your arguments, if you did you would realize that quote had very little to do with my points. It was only intended to show that 10x is a general rule of thumb for total flow, nothing more.

What has 10x total flow got to do with 10x sump rates? they ask for 3x sump rates and 10x total flow, not your 10x sump recommendation, trust me I read it properly, I think you were the one that used it to prove your point, but had not read it properly.

Interesting, did you notice that repeatably mentioned the 10x flow is general guideline tank flow but obviously some tanks require more. I just think it's easier to run 10x through the sump and then add extra if it's needed with power heads. I also mentioned time after time that I'm not arguing for 10x sump turnover nor am I recommending it. My point has always been that people have options, and just because some choose to produce there tank flow differently than others doesn't mean they are wrong.

I never took a side and said what was wrong and what was right. Simply put, people think differently and have different priorities, low flow or high flow, it makes little difference.

Unfortunately if you had made this statement 50 posts ago we wouldn't be still posting back and forth, the fact is in general you feel 10x is the acceptable rate and I believe the slower rate to be better and I will explain.

Really? I'm pretty sure I made it clear from the start, even in the thread this discussion started in.....

Honestly you can use pretty much whatever flow you want for a sump turnover and my argument is that it doesn’t matter. Yes lower turnover rates are quieter and for this reason more common because higher flow rates require more experience to achieve quieter results. In addition lower flow rates require cheaper internal pumps; high flow pumps are more expensive and for the most part louder.

I’ve said it over and over again and feel now that I’m really beating it too death but a flow rate of 3-5x will produce success and so will 10-15x there really isn’t much of a difference. Skimmers are independent and other parts of the sump filtration need to be designed for a certain flow rate. What that flow rate is, is completely up to the owner’s or maintainer’s preference and there is no real scientific evidence to support either option.
