good day to all!!
@vaughnh
wassup? how are your tanks doing? thank you for being a light to my path.

and thank you for always responding to my inquiries, i will be forever grateful.
before anything else, its been cloudy and raining for 5 days now so my aquarium which is situated outside the house and exposed to natures fury is somewhat lacking in light because the sun is on vacation but my plants are i guess still the same nothing much have changed though my annubias are sending out flower stalks, a noticealbe new leaf from my java fern, my cabomba is alive and kicking, my indian fern is growing crazy, my amazon swords have new leaves

, my bacopa seems to be at a standstill, oh my fishes are i guess happy for now.
I would just like to ask by what do you mean ?"It might be possible to use such fertilizers under the substrate, without causing algae" can i still do it? i've read also in the past, i already lost the website, ferts sticks (things that you insert in the soil) that most people use to feed their indoor plants can be used for aquatic plants just by using a bit of it and inserting it in the substrate, is this what you mean by it?
And just like what i mentioned before, since i dont have the luxury to buy pressurized CO2 etc. would it be logical and possible to just use for the meantime a DIY-CO2 for my soon to have 75 gallon tank?
thank you so much in advance for any response
Godbless
