Advice needed for non co2 20 gallon work aquarium

Hi All

just a little bit of background
I'm pretty experienced and succeasful with growing plants but my usual setup is high light high co2

for my office aquarium I would like to set up a 20 gallon aquarium without the use of co2

the substrate will be fluval stratnum

lighting will be 2x t5ho fixtures

probably use bn plecos red ramshorn snails and endlers as my cleanup crew

the plants I'm thinking of using is probably blyxa japonica and e tenellus for a simple scape

would these two plants do well without co2

thx
Ray

I haven't had a non co2 tank for over 20 years so I don't know if these two plants will be ok without co2

The plants would be fine without CO2 but would do a lot better with a dirt substrate. Your light intensity is too much unless you can suspend the fixture at least 12" above the water surface. You are using 2 bulbs T5HO light fixture here. They are generally in the medium to medium high lighting.

You should stride for medium to medium low light. Dirt substrate. Some liquid ferts dosing. Dosing excel is optional but would help the plants a lot. If you really going after the low tech, maintenance free setup, switch your light to a T5 or t8 fixtures, 2 bulbs. Or putting a screen over the tank for your t5ho light fixture. And plants some ferns and crypts and anaubis. Dirt substrate may not be necessary as long as you can provide some root tabs.
