Water changes?

Hi I'm new here, I posted one thread in the intro section.

Setup:
I have a 3 gallon tank, whisper filter & air pump, LED light, whisper heater (78 degrees), and of course a male betta fish (edward).

I have had the fish and tank for 2 weeks now. I've done 2 30% water changes, and 1 90% water change. The reason I did 90% is because I didn't want completely new water for the fish and bacteria.. stuff... If I'm doing it wrong please correct me. (Water is treated before and after changes)

Question:
I'm semi lazy and have read a few things saying 100% water change every week if the fish is in less than a 5 gallon tank (yahoo answers). Wouldn't that shock the fish too much? It just seems more harmful doing a complete water change every week versus a percentage.

Thank you and any tips would be appreciated.

Don't know the answer but your tank is very, very pretty.

I, as well as many other experienced keepers would agree. That's one reason "cycling" is so often recommended. A cycled tank also consistently provides the lowest possible ammonia and nitrites for your fish's safety.

See the stickies and other tutorials on the nitrogen cycle.

Yes, a 3gal tank can be cycled safely and with stability.

Hallyx, thanks for your reply. I have read the stickies and am stuck with the fish-in-tank method. Like I said i've done partial water changes. I don't have anything to measure the ammonia, nitrite, and nitrate levels in the water. Is this neccessary?

I read the stickies, i am assuming i will not have to do a 100% water change for a long time, assuming the tank is cycled. Can i just stick to treated 25-50% weekly water changes?

It can take up to 4 weeks (sometimes longer) to get a tank properly cycled. But once it IS cycled, you rarely have to do a 100% water change (if ever).

However, since you're in the middle of cycling your tank, it would be helpful if you got the API Master Liquid Test Kit (less than $20 on Amazon) so that you can keep track of your water parameters.

Like Mr D says, a test kit is very important to keep track of your parameters. Even after the tank is cycled, it's worth it for the peace-of-mind.

You can fake it in a larger tank, but for smaller ones....

Floating plants and fast-growers will also help reduce the risk.

With no 100% changes, it's less work, yes. But more important is the health and safety of the fish.

I have a betta in a filtered 3 gallon. I do 2 50% water changes per week and substrate cleaning with one of the water changes each week. I follow oldfishlady's recommendations per the sticky on this forum.

sorry guys but i don't think that 100% water changes is unhealthy. If you acclimate your betta right way it not stressful at all. I have 4 bettas. A few of my bettas are 3.5 and about 4.5 and with 100% water changes i never had any problems nor did they got sick yet.
