I purchased a 660gph submersible pump to make water changes easier. This baby is too powerful for my preferences, do any of you have experience with using a dimmer to restrict power? Apparently restricting the output flow is another option. I’m thinking that $15 for a smaller pump is the sanest alternative.
I use submersible pumps to drain my tanks. I have a few different sizes that all have the Python quick connect ends attached. Having different size pumps is nice so if you want to just water change a 10g your don’t have to use the same as the one you use on your 125g.
I most likely will opt for a 90gph in the near future. Although the good news is that I made a hose to 3/4 PVC connection with an elbow that sits nicely on the aquarium lip and a Tee connector at the bottom to slow the output, just did a water change and it works great!
