I have made the decision that I want to turn my 75 gallon into a coldwater tank for goldfish. Don't ask me why but it's mainly because I need to restock and just don't want to spend the money right now. I can easily move the current inhabitants to my 29 gallon which is also understocked. In any case, I want to keep it planted and have a good start with plenty of stem plants like Java Fern, Val Grass, Amazon Sword and Anubius Nana.
The question is, what substrate would give me the best results with very little maintenance? I have plenty of lighting with 4x65 watts of power compacts (too much maybe). I know I will need to do gravel vacs as normal because the goldies are pooping machines. The main thing is I want something that will provide the plants with all the nutrients they need without having to add ferts of any kind.
As for stocking, I only plan to have 5 -7 in the tank. I will pull them from my small back yard pond (about 150 gallon) and they will be about 3-5 inches from the start.
Thanks in advance for the help.
