Need input on remineralizing RODI water for planted aquarium

I have very funky water where I live, and this has prevented me from having a successful planted aquarium in the past. My LFS recommends using RODI water and remineralizing, this is what they have to do in order to keep plants alive in our area. The combination of products they suggested I use was (all Seachem):

Equilibrium
Acid Buffer
Alkaline Buffer

And then Flourish and Trace fertilizers for the plants

This seems to work for them but it also seems less complex than other remineralizing plans for planted tanks that Ive seen. Simply put, does this combination of products seem sufficient to you or should I figure out a different regimen? Is it missing anything?

Also for reference I am aiming for soft water with a ph of 6.5-7 for specific killifish and plants.

Just use RODI and Seachem equilibrium. Don't need those other buffers, they're just trying to make a buck off you. If it makes you feel better you can add a sodium (baking soda) or potassium bicarbonate at a rate of 1/16-1/8 tsp per 5 gallons of water to raise dKH by ~1. For killifish you should add only a very small pinch of bicarb to the water in order to feed your bacteria.

Fluval Spec V
7x Microsynodontis sp (1)

10g Terrarium
1x Cranwelli Horned Frog

I'm with @Jeffww on this one. Equilibrium is fine without the rest.

And if you want to get really technical with baking soda, you can do some gram/milligram measuring to dial things in.

I recently tested a box of baking soda from Kroger and found that 1 gram per gallon raises KH about 8. Which obviously means 0.5g raises a gallon to KH 4 and 0.25g to KH 2ish. This particular variety of baking soda increases TDS about 33-35 for 2ish degrees of KH.

Define planted tank? Low tech or high tech with co2?

Define specific killi and plants?

But agree with all you really need is equilibrium.

Niloc Thrive is a good AIO fert option and way better price to dosing ratio if your just keeping plants in a low tech, no need for 2 part solution really, just dose usually 1/3 to 1/2 strength on daily or every other day schedule. KISS philosophy dosing.
