CT_ Posted January 19, 2021 Share Posted January 19, 2021 How much lid ventilation is necessary? My toddler has been putting stuff in the hood gap so I covered it but that only leaves a little bit of space around the HOB and some holes on either side for the heater wire. Is that sufficient ventilation? Link to comment Share on other sites More sharing options...
Brandy Posted January 19, 2021 Share Posted January 19, 2021 Yes. If you are ever concerned, you can always add an airstone. The HOB will likely do the aeration for you tho. You are in far greater danger of poisioning your fish due to toddler, than suffocating them. 1 3 Link to comment Share on other sites More sharing options...
Maggie Posted January 19, 2021 Share Posted January 19, 2021 It just occurred to me why I never gave a single thought to having an aquarium back in the late 80s through the early 2000s. Three kids. 😃 2 Link to comment Share on other sites More sharing options...
lefty o Posted January 19, 2021 Share Posted January 19, 2021 it doesnt need much. bonus, tighter the lid, the slower the evaporation. Link to comment Share on other sites More sharing options...
