So I found a 10 gallon with light hood on craigslist for $15 and it is in pretty good condition, no cracks and might or might not need a new bulb. The fish these people had did not die of disease but of old age or getting caught in the filter they had for it.
Can I just rinse and scrape with hot water since diseases usually die out of water?
Or should I use vinegar or bleach to be sure?
Do I NEED to have a filter in a 10 gallon or is it just recommended?
If it is a NEED can I wait a month or two until I can afford a nice one?
Do you HAVE to cycle a 10 gallon? or is it just helpful?
