I was just wondering if it would be ok if I didn't add any CO2 or fertilizers in my aquarium. I will be heavily planting it with low light requirment plants. These are the plants:

- Jungle Vals
- Water Sprites
- Java Ferns
- Java Moss
- amazon sword
- pennywort
- brazilian frogbits

I was thinking of using Flourish Excel, but I've read that Excel melts or kills Jungle vals. And I most of the plants will be jungle vals. But I think I may add some Seachem Flourish Supplement. Would that be ok?

I have 2 hagen's Life Glo T5 46". They're 54 W's each so I have 108 Watts. The tank is a 75 gallon. The substrate is sand.

Thank you.

I'm planning to do a "silent cycle" too. So I'll buy more plants

Co2 and ferts are good for all plants. Low light or not. You are correct though about Vals and Excel. Remember....liquid ferts for water column feeders and Root tabs for root feeders.

its hard to say for sure but it certainly is possible and alot of folks keep beautifull low tech/low light tanks. some of it depends on the density of your fish/plant stock. tap water condition, substrate etc.....theres a good possibility you could be fine without adding any ferts. not adding co2 shouldn't be an issue, it probably would be best not to mess with it. in a worse case scenario you might have to dose a tad of macros or add a few root tabs.

You can add them, and it might help them a bit, but low light plants use less CO2 and less nutrients, so they likely wouldn't benefit too much.
Slow-release root tabs are always a good idea for rooted plants. For floating plants, I rely on Vitachem to provide the trace nutrients needed, and the fish food (processed by the fish, of course) to provide the nitrogen and phosphorous.
