I'm up for any adjustments to my set up as i'm new and only looking to learn and keep the best atmosphere as possible for my betta fish. I absolutely have learning intentions here. I've owned 3 betta in the past and am new to aquatic plants.
My first intitial thoughts:
set-up...
3-5 gal. tank
Possible plants
Lucky bamboo.
Pink water lily.
Anacharis.
Fissidens splachnobryoides.
Cryptocoryne Wendtii.
Gigantea (Anubias gigantea)
Anubias, Petite Nana
Aponogeton, crispus
APONOGETON ULVACEUS
*My water might have a bit more iron in it than usual I think. Any good plants not requiring CO2 for this?
*Will I need CO2? Can I take out some plants (which ones) to avoid needing CO2? [[[If you have decided not to add CO2 to your tank you may need to add it later on. The best way to tell if you will have to is to do daily testing of your water parameters and keeping an eye out for the tell tale signs of "white powder" forming on the leaves.]]]
*I ordered 100% Blackwater Extract Catappa Indian Almond Leaf and Catappa Indian Almond Leafs to go with it. These are good for mixing into conditioner, correct? :)
*You need water conditioner AND to let the tap water sit out- both are required? Will these affect the plants?
*What conditioner will be best for my set up?
Lighting: 10 watts. A little less if smaller tank- *is it better to go over or under with wattage?
Substrates I like: Turface or Seachem Flourite or CaribSea Eco-Complete [2-4" in depth]
*Are there any subrates that are NOT good for betta fish or plants mentioned (toxic, etc).
*Washing hands before messing with inside the tank: Is it okay to wash your hands before cleaning and such- washing hands and fish items in tap water and drying (do you need to wait for two hours with objects, and why not hands?)- i'd like to know ;D
*I always wondered if its possible to have the right set plant-wise up to not require chemicals such as water conditioners, is a curiousity only.
3.69 gal tank (how do you do good measurements with .69?)



*I pulled out this tank I acquired over the years from a garage sale and cleaned it out best I can with hot/warm water. But.... I am not going to try it until I know well it's perfectly safe. On the outside there is metal, but only on the top part does it seem to be closer to contact. Is this tank safe????
* I should probably use a toothbrush to brush off the gunk as well, but I thought chemicals or toothpaste would not be good even if rinsed out really well?
I will do my best to update what questions have and have not been answered on the original right here, thank you for all your help!!!!!
