yes, i believe it shouls lower ur chiller efficiency. thus takes longer time to chill to meet your desired temperature.

If a man could beat his own fantasy. Then to only breed in captivity. Then its pointless.

Genesis 1:20

And God said, Let the waters bring forth abundantly the moving creature that has life, and fowl that may fly above the earth in the open firmament of heaven. And God created great whales, and every living creature that moves, which the waters brought forth abundantly, after their kind, and every winged fowl after his kind: and God saw that it was good. And God blessed them, saying, Be fruitful, and multiply, and fill the waters in the seas, and let fowl multiply in the earth. And the evening and the morning were the fifth day.

Does this reduce chiller efficiency?

For example. Arctica 1/3 DBE-250 is rated 480 - 2400 GPH. What happens if I run an Eheim 1250 connected to it, which is rated at 320 GPH?

I am using 1/4 HP (Model DBE-200) with Eheim 1250 for my 3ft tank.. So far look ok... except need to clean the pump every 3 to 4 month.. cause I am using the eheim filter at pump inlet.. I found the chiller efficiency drop via debris build up trapping in filter wool... my temperature set to 26C... otherwise so be safe... In other words depend to our tank sizes and heat induce in our tank also critical...

try to calculate using chiller calculator supply by JBJ... Add more buffer to your input so that we will not under estimate the chiller output..

for eg.,

Cheers..
