So far I collected from my RO/DI almost 100 gallons of ASW. I got to say, collecting real water is so much easier.
To do that I get in my Jeep and back up to an ocean, In my case, the Atlantic.
I sit in my car and enjoy the sounds of the seagulls as I watch the fish jump.
I stroll to the back of my car and open the hatch, remove a bilge pump on the end of a 50' hose and throw it into the water.
I take the plug and insert it into my car's power outlet and gaze at the water going into one of the 10 gallon buckets I have.
After about 2 minutes, the water stops and I pull back the pump to clear the bowling ball size of ulva seaweed that is clogging the thing.
Throw it back into a different spot and look up and down the beach as I wait.
Off in the distance I see three beautiful Ladies walking in my direction. I live near the end of Long Island where a few Supermodels live so I figure one, or all of them are some of those wanting to come up to me to learn about reef tank husbandry, how I go about changing water, asking about quarantining, medicating or what is my favorite dance move.
As they get closer I notice they are elderly (but classy looking) Ladies who just want to know what kind of toxic waste I am dumping into the sea.
I explain my water change method and how natural sea water, IMO is better than ASW. How I go about cleaning it, heating it, and transferring it to my tank all the while as one of the Ladies, the least classy looking one is calling 911 to report a "Deviant" dumping used oil into the Atlantic.
