Just trying to give some perspective on water amounts and prices:Unless you're using RODI or distilled water (and if you don't know, you're not) 27 gallons a day is not much at all.
* A ten minute shower uses about 27 gallons of water with water efficient shower heads.
* Flushing the average water conserving toilet uses 1.6 gallons per flush. Old toilets use double that.
* I live in a desert, and my water prices is about $2.27 per thousand gallons. This works out to about $0.002 per 27 gallon water change. A 100% change every day would cost about six cents per month.
* Lookup the price per gallon/liter of your city's water and do the math. It's probably so cheap it's better to worry about the fish than the cost of the water.
I totally get wanting to conserve water - I live in a desert. I 'dump' my old tank water into my lawn & garden during the growing season, and use it to wash my cars.
Water changes in your 27 gallon aquarium will barely make a dent in your water use. Humans use a ton.
its not so much the water use, its the sewer use. My bill comes out to $300 every 3 months and the majority is not the water its literally the sewage/pipe use. I live in washington dc so its more expensive then the average state.which sucks, i just want to find somethin even its temporarily until i can get my 27 gal back. i also have to factor in the electricity. with the 27 gal i use two filters since its a bigger tank.I know it doesnt seem like it would affect much but it really does with all the electricity i use too connecting my filters, the air bubbles etc. Im willing to get my 27 gal back but at the moment I cant because its in my backtard and its covered with ice so i cant bring it in alone since im a small girl lol.
i was wondering if in the mean time i should use melafix?
and also i dont see cyst in his body it just looks like his scales are deteriorating and he has cotton like substance in that side of his body, I would like to add the melafix but if salt is better i would do that too. i just want to make sure the melafix wont hurt him
