honestly i dont understand how you have so little algae with using tap water.

Using RODI gives you so much control over your chemistry, the only things that go into your tank are what you desire to put in there. It will cut down on that mysterious x factor. Do it, you know you wanna.

true to mystery factor, not sold yet though.

[i have crabs]

calgary uses alot of silicate in the tap water which is a big factor in diatoms, other than that there is a high tds so plenty o gunk in there, using zeo probably counters the alge by using up the bad stuff but im just guessin
i used tap water for years and battled algae and cyano non stop, within weeks of ro/di water it stopped and never happened again,
in a fish only tank i wouldnt stress to much but in a reef i thinks is a bad choice

Doesn't look you you have a problem just using tap water. Would say unless you're having a problem with algea or cyano why bother?

^ My thoughts exactly, and I'm a RO/DI fanatic. What you're doing is working, so don't mess with it!
