can anyone tell me or make a suggestion on water loss.I have a 155 galloon bow front that has no leaks no glass covers and seems that I am adding 15 galloons of water a week is there anyway that this can be minimized thanks
tank has only been up for 2 months no fish yet but my 75 galloon fresh has been up for 2 yrs and yes it does go through alot always but fresh is easy if the fans are the problem do I need them on 24 7 or can I shut them down in the cooler weather some said their for oxygen exchange thanks
that helps if not the water loss the electric bill lol! ok now that the tank has been up for that long would it be a good idea to start with fish or will it mess up the water also any suggestions on fish have polys doing great some sponges feather dusters and mushrooms it seems thanks
i added about 6 gallons a day to my 125 in the summer.
you said "fresh is easy" ....i think you meant to add top-off water to. saltwater tanks are exactly the same. DO NOT add salted water as topoff water. when salt water evaporates, the salt stays in the tank. just add fresh water for topoff.
I evaporate about 1 1/2 gallons a day on my 46g tank, so I think 15 per week on a 155 is actually pretty reasonable. It's well worth it for me to spend a little extra money on top-off water than the extra electrical cost of running my chiller more often.
One thing you could consider is putting some type of cover, even if partial, over the sump. Could lower your evaporation rate. If it wasn't for the added humidity in the air (being that I'm in GA, extra humidity is highly undesirable), I would not have a single problem with evaporation, though.
Evaporation will depend upon SOOOO many factors...i..e elevation of your house compared to sea level, humidity outside, humidity inside, where in the house the tank is, the amount of surface area the tank is exposing to the air, if you have a hood or not, how hot your lights make your surface.....etc.
My 75 is in my room which is on the end of our air conditioning chain. There is barely any evaporation taking place....prob a gallon every two days. My eel tank is on the porch...in Florida. Due to the humidity outside I dont think Ive ever given it topoff water...just water changes. WHere as my 10 gall tank in the Living room is at the beginning of the air conditioning chain and I CONSTANTLY add water.
All in all, evaporation IS a good thing. I take the opportunity to add calcium to the water.
