So I don't have any clean 5 gallon buckets since we used all of ours to haul bricks after tearing down our fireplace and carrying dirt to fill in the garden, so I'm wondering if there is a way I can make a couple of them aquarium safe for water changes. Secondly, when I did my last water change, I had to use a pitcher that was either 1 quart or half a gallon and it doesn't say on it, so I just added probably more than enough water conditioner to the water each time before pouring it in just to be sure. It's been about a week and due for a another water change and it didn't seem to have affected the fish at all. The 4 harlequin rasboras I have at the moment are doing really well, although I will be getting 4 more to complete the school this weekend or early next week (I didn't want to overload the bio filter at once since I had just finished cycling). It is stress coat+ by the way. I just used a turkey baster to get the water conditioner since the cap only has 1ml, 5ml, and 10ml and 1ml would treat 2 gallons so I just guessed with the turkey baster and ended up probably putting more than I needed just to be safe. I assume it's safe, but if I repeat this in my upcoming water change since I don't have clean 5 gallon buckets to measure more accurately yet, could this be bad for my fish? I probably ended up putting more than 1ml in each 1q-2q bucket each time because I didn't want to undershoot it and kill the bacteria or fish with chlorine.
