Are 100% water changes safe to do? I've read that it's safe for the bacteria given the substrate stays wet. I think one of my tanks has a bacteria bloom sbs the cloudiness won't go away after 50-75% changes. Also, will 100% changes lower ammonia levels or is it better to just do two 50% changes every week?
100% changes are only for non-filtered tanks.. Your tank is filtered, correct? You stated a bacterial bloom has occurred so that really happens to filters. It's really bad to do 100% changes when cycling tanks as the beneficial bacteria will all die of the chlorine. :\ Water changes will make the bloom worse so don't do them... 100% changes are safe and will take out all ammonia in the tank
Lebron, yes! Both of my tanks are filtered. My 5 gallon is super cloudy, but I guess I'll just keep with my normal water schedule and hope it goes away with time. The ammonia question is for my filtered 10 gallon tank. Both are still cycling so it looks like 100% water changes are out of the picture lol. For my 10 gallon should I just continue with two 50% changes a week?
The plants will help at the end.. Lol. Yep, still do 2 50% water changes per week. 1 with a siphon, and 1 just water. The BB (beneficial bacteria) live in the gravel too, so you don't want to disturb their "reproductive stage".
I forgot to mention that my 10 gallon currently houses 6 harlequin rasbora. I jumped the gun and got a full school instead of getting 3, and then slowly introducing more over time. So that was my bad and now I think I have to do extra maintenance to make sure these little dudes and dudettes don't die. I've only had them for 5 days now, they SEEM fine but time will tell. I love feeding them, they're like little piranhas.
