I had the same issue with the RO couldn't get it consistent. May of been too big and tank not old enough? The vertex has been rock steady and started working day one.I was hoping you liked the RO as i am looking at the 150 elite, i hated my vertex 150. The thing was AMAZING.... when it worked. It overflowed for no reason more often than not in my experience and had to be adjusted every few days to skim correctly. This time around i am going with nyos, deltec or RO.
Can you go into detail non how you have your siporax in there? I noticed its stacked, do you have it in a container? Do you do any maitnence with it or just let it sit?
The siporax is stacked in a container I found at bed bath and beyond with my wife one day lol. It is a shower basket had a handle but I took it off. I now have two the macro reactor is sitting on the new one but I haven't filled it with siporax yet. Maybe I will in the future. I am using the larger rings also found a deal on eBay for small bulk purchase. I have move it around a few times but haven't shaken it or anything.
