Absolutely. keep the gravel fine, as in small pieces. I have Eco Complete in both of my tanks, but you don't need it. You can just get fine gravel and you are all set. Heavy root feeding plants like Swords might need added root tabs but most will just benefit from a dose of Seachems flourish comprehensive fertilizer weekly.
- What kind of filter is recommended for this size tank? same as the small tank, you could use a HOB, SPONGES or my choice for a 125 would be a canister filter. There are many kinds to chose from. It will really depend on who will be housed in the tank.
- What are some combinations of fish I can put in it? So many choices but it would be hard to help you chose until we know more about your water parameters. You could start by testing your source water (the water from your tap)
- How long would you recommend cycling a tank of this magnitude before putting fish in? That depends again. If you truly have it heavily planted, you can add a few fish right away (3-4) You would want to make sure the first fish are hardy fish. Keep an eye on the water parameters and keep it clean. If you do not add plants, You will need to wait through a full cycle and that usually takes several weeks.
- Are salt-water tanks hard to manage? Would it be better to do a fresh-water? I think it all depends on what you want to put into it. I prefer fresh as I find the salt water tanks a bit more hassle but each of us has different things we consider worth the effort or not.
- Any other advice? Make sure you put the tank in a room where the floor can with stand the weight. A 125 gallon tank weight a LOT with the water, fish and everything else. Salt water is heavier yet with all the live rock in it.
Good luck, and hang around there is a ton to learn here and some wonderful people willing to share their ups and downs of the fish hobby.
