so i got my 75 gallon tank with a magnum 350 canster filter. So i just got this bass i used 95% lake water and 5% clean water. I was wonder if i still need the air bubbles for the bass. Also when should i do a water change i want to do 20% everyday, is that too much? Because the water yellow and smells kinda. Since i have go the water from the lake does it contain the bateria i need to eat the waste? So could i just put the fish in the power the filter and be good. I want to do water changes fast but i understand i shouldnt do them to quick. Whats the best do you think. Or would the over flow work better?
That smell is excess Ammonia. That's a bad sign. In all likelyhood, the lake water is filled with bacteria or algae that is now dieing and producing extra ammonia. I would definately do some water changes, and use fresh water, 10% every 2 days for the first 3 water changes, then cut back to 10% per week for the next 4 water changes. After that, as long as your filtration is adequite, you should have enough good bacteria in the filters to remove the waste and convert ammonia and nitrite into less harmful nitrate. You should still do a 10% water change every month though, just to keep your nitrate levels within reason.
PS - hope your bass is young, because a 75g tank won't be big enough for it for too many years. You'll probably want to step it up to a 125g or even a 300g tank where they will have plenty of room to swim.
For bass the bigger the better. I think you should do a 50% and the follow up with a 20% every other day. Its what I did whe I had stripped bass i an 180. I had them untill the got to 18" and were banging against the tank cover when they were fed.
You shouldn't have used any lake water in your tank. As long as you do the drip method it should adjust to your water ok.
If you want one your going to need good filtration and a very large tank. They eat a lot and are very greedy (i've had a small 2 inch one take a 3 inch piece of krill out of my 10 inch needlenose fishes mouth).
Large plant thickets at each ends of the tank help out greatly, it makes them more secure and are more likely to eat right away. Straight vallisneria is THE BEST plant to do this with. It's what all the bass here hide in and it's what I use in all of my freshwater tanks.
If you need any specific help just ask, i've raised plenty of smallmouth and largemouth bass in tank settings. I currently have one right now hitting the 3.5 inch mark destined for my future indoor pond.
As a note, it will need about a 200 gallon tank to be happy when it grows.
