Planted Community Tank parameters

Hey guys,

First post.

I have a Waterbox 4820 Plus+ coming in June and am looking to keep a moderate/heavy planted tank with community fish.

I currently have a 10G that I have had for 6 months now with quite a few fish in it (21 fish), and some plants. Tank gets regular water changes, and I have enhanced biological and mechanical filtration on the tank to help with the overstock. Parameters have been perfect, and the fish are doing very well. The fish from this 10G will be getting moved over to the 4820 once it is cycled, and that led me to getting into my water parameters more in depth... so more on that below.

Tap water parameters (City water, with a whole house softener/yearly carbon block):

Tank parameters in the 10G:
500-600TDS; this was the result of using warm water to bring temp to 78F - apparently my new water heater doubles the TDS from cold, the heater also gets the softened water. This is what led me to going ham on water quality.

Fast forward to the present:

Picked up a SpectraPure MaxCap 180GPD 2:1 RODI system, an Aquatec 8800 booster pump, and a Norwesco 65G NSF storage tank to start making pure water, as I will eventually have a Waterbox Reef 130.4 running in the house as well, so eventually needed this kind of setup anyways.

So since I was planning to use better water, and control the parameters myself in the 4820 I figured it would be a good idea to slowly titrate the 10G water with my new water and acclimate the fish slowly to avoid any wild pH swings, or osmotic shock from the sudden shift in GH; this process of acclimating them is already done and current tank conditions are 7.6pH, 4GH and 4KH.

I currently take my RODI water in 5G water changes and bring it to 78F with a heater, and then add 1/2tsp Equilibrium and this raises my GH to 4, and then I add a rounded tsp of baking soda and this brings my KH to 4 as well. pH when I add it to the tank is about 7.8-8.0 and then once the tank change is done it balances out to 7.6pH and I see little to no fluctuation over the week/2weeks before a water change.

So tank chemistry at current is:

around 300TDS
~0 ammonia
~0 nitrite
~10-20ppm nitrate (between the plants and biohome pellets it seems to stay stable at this level)

I have not started dosing ferts or anything as I was dialing in my chemistry still, but I was wondering if the 4GH and 4KH with a pH of about 7.6 is reasonable - from my reading it seems like it would work for my goals, but I also find people saying I should have higher GH.

Oh yeah, the fish I currently have below, I am still learning the plant side of it - I currently have moneywort and anubias, and previously had cabomba in there but got sick of it getting leaves everywhere.

2 peacock gudgeons
4 panda corys
2 long fin blue danios
4 penguin tetras
4 harlequin raspboras
4 oto cats
1 bumblebee platy

Appreciate any feedback!

Don't use any of your softened water in your tank! Hope that's all R/O you are using now?

And yes your Gh could stand to be higher. 6dgh is preferred, if not 8 or higher depending on animal needs. Some of your fish might actually prefer that higher Gh although you have a mix.

Don't worry too much about pH. Just make sure kh/gh is stable. Kh doesn't need to be 4. Plants actually prefer lower kh. But if it makes you feel better to be at 4dKh than no worries.
