Test the well water.
We use only well water now.
Filter the water with a filter sock contraption.
We catch the water before it hits the softener.
The Bubble bee gobies like the hardness of the water with fresh water changes.
The fat supposed females are usually colorful, but the thinner bodied bumblebee gobies get more color back from the fresh well water for sure. The fresh minerals have to have salts as well. I need to find out where I'm at as for salts in the well water for curiousity's sake and the gobies. We've had them for about 2 years now with well water.
Sooo, In the Johnny-rigged contraption-
An old pump pumping water over a big clean Brute trash can.
Garbage can and a sock basically.
Our well water stained orange filter sock cleans out in the wash machine.
We tried using foam hydro sponges to clean up the orange grit, but the gritty orange stuff (possibly iron) was getting iffy to deal with in comparison to the sock.
A simple sock holder will work, but our stronger pump blasted the sock too much.
Lots of clean water for the tanks required a double stuffed sock and a pvc end cap in the bottom of the sock to help with the harsh blasting water for a quick fix.
The socks were getting a white unused section from the pump.
As stated before the socks do get orange where they are doing the job filtering well water.
Some reef sumps have a great 1st section called a Berlin method I believe.
The idea is to get the water to fill up a small flooded section first and passively pour into the socks next (see pics).
We were so tired of going to the 5gal jug fill up at the store, well water was a must win operation.
If the Berlin method as I think they call it, can be rigged, the sock extraction is done in seconds.
I like it.
I need this little 1st box in my sump as well.
