Yeah I just re read my post, I should have specified that I meant I wouldn't need to vacuum (possibly). I do water changes every week. I used to do them on Saturday, but we changed the substrate (from gravel to sand) mid week, along with about 60-70% of the water that day. So I am going to do a small one today, and then a larger one on Saturday again to get back on schedule.
Thanks for watching out for me though.
