Hi so a year ago I was given a 5 gallon Eclipse corner 5 fish tank and I have 2 clownfish inside along with 2
live rock. I mostly do weekend trips which is no big deal but I am going for a week this time. So the problem is I do have an auto feeder but because of the style of tank it is, When it is sitting up there the lid is really open and the evaporation rate is obviously really fast. For a weekend alone i will lose say a finger thickness of water. Earlier this year I did a week trip and I put the auto feeder as always and once I got home the water was literally close to half way down which also now meant the built in filter system etc also stopped working. Luckily the fish made it I just do not want to go through this again. So here are my options now..
a) I can top it up normal before but prior to doing that I can remove some water from it and keep it in a jug as is beside the tank and maybe ask somebody to show up once or twice throughout the week to top it up and that way the auto feeder can do its thing but I am a little worried about how good it is to keep the fish water aside for a few days. Im not sure if it can go bad before someone comes and tops it for me
b) I put the feeder and i maybe duct tape the huge opening of the lid being open. Would that slow down the evaporation rate drastically where I wouldnt need to pull water and keep it aside to have it refilled midway through the week? Because with me home and the lid closed normally the evaporation rate is very slow and barely moves as long as its closed
Any advice is greatly appreciated and also should I reduce the number of hours the light turns on?
