RO/DI top off water

[Topflight2]

Hello! I read that it is not a good idea to supply top off water directly from my RO/DI because it will cause chemistry spikes in my aquarium water. Is this true? Is there a workaround?

I have a 150 g w/ 3 250 w mh. In the process of installing a RO/DI and looking for a Calc Generator. After doing so, I will be adding corals to my current fish only reef tank.

Thanks!

Some people do hook it directly up to thier sump. The only negative I've read is the constant on/off of the system is not good for the RO membrane. I have a 15 gal bucket that is attached to the sump and tops off the water level via a Tunze top off system. My RO/DI is attached to a 25 gal drum.
