No...external/internal is how you plumb it, submersible/dry is type of pump. Personally I run an internal config with a pump that can run dry or submerged (submersible) If I had the room id love to run external config but would likely not use a dry only pump due to noise and limited future options.Wouldn’t that be the same thing.
I use the curve 7 skimmer. Return pump is Jebao DCP-20,000. The return pump is so quiet I have to look at the clear check valve fitting to see if there is flow.which model do you use?
I am running an Iwaki external inside my cabinet. Amazing pumpI would imagine most people using external are using it in a basement sump or fish room type of application, probably not that many in cabinets. I also think those applications are where each particular pump shines, save for the real nice DC pumps made for high head pressures.
I have a backup of my external pump. I can literally disconnect 2 hoses and connect to the new pump. Easy peezy.I don't see it as a question of trust at all. I see it as how easy is it to run multiple pumps for redudnacy when one fails and how easy is it to replace when one fails. Internal pumps with flexable tubing I've found to be easier than hard plumbed external pumps even if union fittings are used.
With an internal pump I only need to disconnect one hose. And with two pumps running if one fails my systems can go days or weeks without anything dying.I have a backup of my external pump. I can literally disconnect 2 hoses and connect to the new pump. Easy peezy.
First of all the number one rule for me is; NO internal pump ever, heat, plastic DC NO WAY. The life is so, so short. Ever had a pump go down and be at the mercy of your next pay check..? Not for me period. It is nothing to plump a pump in, I have never had one leak or drip ever!. With that being said, there is ONLY one pump I would ever both buy and use. I bought a **Japanese Iwaki 100r** 25 years ago it has pumped right at 2160 gallons an hour, 36 plus gallons per min at a head height of 39ft at 25psi. I run 265 gallons plus total on my system. 2 tanks a 90 and a 110 and a 100 gallon sump of sorts, it is a 100 gallon plastic horse trough with my sump in it, I keep that down in my basement lol. Heavy duty pumps these are and with a huge head height. It went bad on me right at 4 months ago now. I bought another one from BRS ( I shopped very extensively both new and USED 1st ) for $478 dollars free freight. I would use NO OTHER PUMP PERIOD EVER ..! It lasted right at 25 years! 365 days a year, 24-7, for 25 years. That breaks down like this.. 24 hours a day, 7 days a week = 168 hours a week, 168 hours a week x 52 weeks = 8736 hours in a year, 8736 hours x 25 years = 218,400 TOTAL HOURS THIS PUMP HAS RUN NON - STOP... Now someone out there tell me, is there a better pump out there..? I have never changed any part on this pump ever, not an even the impeller. Nor ever cleaned it..! No other pump will last this long ever. They have never changed anything on these pumps at all. I did talk to the factory direct no changes ever on them. And I did get the dark gray replacement pump just like "I" had before, again bought the new one from BRS aquarium ** Japanese only. No other pump will ever last that long ever... NONE... I also after a little homework, I can replace $5.90 in bearings to rebuild my OLD Japanese Iwaki 100r pump. Again anyone tell me... Some 40+ years
