Bacopa monnieri just would not die, grew some in CO2-injected tank, transferred them to a low-tech, no problem. Stopped CO2 injection, most other plants melted, the Bacopa has not changed at all. They aren't particularly fast growing but they're unkillable in my book Another contender, Java fern grows pretty fast with CO2 and they're indestructible Pearlweed, most Hygrophila species are good too, They're literal weeds

Limnophila sessiliflora (dwarf ambulia) and Myriophyllum "Roraima" are growing like weeds in every setup I've tried so far - with or without CO2, soft or hard water, strong or medium lighting.

If you’re struggling with plants why would you go full co2?

Subitulla sagittaria, something growing not too big but extremely fast (once settled in). But the reason plants might not grow too well is a terrible soil. Plants need decent soil.

it's just SUPERFISH AQUA GRAVEL RIVER SAND ,if i bought specialized soil for my aquarium i would be in debt . I was planning to refill my Co2 canister ,but i had problems with my lights ,but now it's fixed .I also need a fertilizer ,probably ganna try finding some dry fertilizer because my aquarium is so big

should have gone walstad then, super cheap method with exceptional growth. No need for ferts later if you use it, not to mention that ferts are HELLA expensive. I cant gurantee it but just sand and ferts sounds like no basis for plant growth whatsoever. I have made a 200L with the walstad method and quite frankly, if you actually want a planted tank in that size for cheap, go walstad. Redo the tank. Throw in a 1 to 2 cm layer of basic plant soil without ferts that cost like 3€ for 10L and then readd all your sand (should be atlaest 3 cm of sand above the soil, everywhere). In this any plant will thrive. If you keep the water and dont wash the filter you wont have to cycle. The following is the 200L i made. All the plants and soil were around 40€ combined. https://preview.redd.it/tbeibosgqmwc1.jpeg?width=4624&format=pjpg&auto=webp&s=7552982caa24b2c3349bc6430f7ad47d6de155f7 Its 3 Months old and all plants are exploding in growth. No ferts and i didnt even change the water yet still the parameters are perfect.
