1. I did not use ro/di water for the cycle and had crazy algae issues to deal with.
2. getting Cheato in my sump has been great, params are perfect, and i still have to rip some out every month or so.
3. I use phosguard and chemi pure elite.
Kwik, take your time, get everything you need, and go for it.
What are you still getting?
I've upgraded my list by replacing my two 6045's with 2 Vortech MP40w's; love 'em.
