Rodi and dosing

[Llyod276]

I'm starting rodi in my tank. Right now it's still 95% (well) tap water. The question is do I have to dose trace elements and strontium molybdenum etc if I am using rodi water. Common sense tells me yes, and if so should I go the full monty with a dosing pump and Triton esq system? Thanks in advance.

If this is/will be a Saltwater tank, pretty much all salt mixes contain enough elements to start you off.
What you need to dose moving forward will depend on your tank inhabitants and WC regime.

The regime is about 20% per week. Until the rodi is mixed in so I'm guessing all summer. But come winter, yeah, not gonna lie prolly drop off to 20% per month if I'm lucky. Water changes are done in the basement and I have to go outside for that, brrr.
Inhabitants are well... let's just say I'm learning an expensive lesson and want to change my evil slothful ways...

There's no way without testing to know if you are getting too much or too little of any given element from the well water.

And as a side note, well water can have some weird stuff in it. RODI is just safer. With 20% water changes per week, I think those would add quite a bit of trace elements. Unless you have a very high demand coral system, I would think you are fine.
