What 2 part do you use and why?

I haves used EVS, Brightwells and BRS 2 parts with good success. I switch to kalk due to cost and easy of use with my ato.

I use brs two part and am thinking about trying the me brand. I have to do some more research into it.

I've always used BRS two part.

Nice tank, beautiful aesthetic! I use BRS and ESV. Also all ATO is kalk.

Another vote for Randy's two part. I've been using it since 2008 when I came across Randy's article. It's so much cheaper on a larger sps system. I use a ghl doser 2 which keeps my levels rock solid.

I spend the money I save on better pumps, lights etc. I think it's a better return on my investment.

Hate to think about how much money I used to spend on aquarium brand supplements.

Ive been using b-ionic since 2002 and is pretty much my go-to for maintaining if not using a reactor, but I dont recommend using it to make dramatic increases of your levels as you might spike trace elements in the process.
Get close to NSW levels by doing WC or by using CaCl / NaHCO3/MgCl3 then start using b-ionic to make up for your systems daily consumption rate.

I use Randy's two-part (+ magnesium) (Recipe no 2) for just over nine years. I use this method to supplement limewater in these days though. I use Fauna Marin salts.

I've been using aquaforest comp 123 for the last year and a half. I never change a lot of water so the trace elements help in my case. I used Randy's recipe for years but I noticed a huge uptake in consumption over a 4 month period after switching to comp123.
