hey
When you first introduce them to the 400 leave it up around 2 foot, then slowly over a week or so drop it down...If its vented you can get it prety close but they need time at the beginning to adjust...

Just to add... put your hand under for a full minute. If your hand is uncomfortable during the minute, than the level is too close. All the best, E4A2S |
