HI everyone. I may be showing my ignorance so feel free to correct me! I work at a local pet store and had a customer tell me that some other fish person told him that in order to get his Common Oscar to grow faster he needs to do 25% water changes every other day :WHOA: . Is this true? I told him that He shouldn't change anymore then 20% once a week unless he was trying to induce breeding or giving birth. but had never heard of water changes speeding up the growth proccess, and only frekwent feedings of hi protein foods 2 or more times a day would slightly increase his growth rate. NOW! What do you guys think? Was I wrong in my advice and or have you ever heard anything like this before? Thanks for you guys feed back in advance.

THE MORE THE BETTER :grinyes:

i do 50% on my tank once a week

sometimes twice :grinyes:
 
But wouldnt that much and frequent of water changes remove a lot of the beneficial bacteria in the tank? and what about the tempature fluctuation?
 
I always thought the most you could do would be combined about 30 or 40 percent a week. If not, I will start doing 50% twice a week. I don't mind water changes, and if it helps the fish I would like to do it more than usually. I am pretty new to aquarium maintenance but water changes don't seem like so much 'work'. But I do only have a single 55 gallon.

there is no benificial bacteria it the water column

thats a myth, the good bacteria stay clung to things such as your bio media, gravel, sand driftwood, etc, etc.

bacteria in the water column is not a good thing becasue that bacteria is the BAD kind, that can affect the health and well being of the fish.


most fish can take temp fluctuation easily

its the extreme that will kill them.


but say you only do a water change of 20% once a week and then you all of a sudden do a 50% water change, the parameters between the tank and tap water and very differnet to the almost extreme, and that why you get fish that die of shock.

best to keep up on adaquate water change percentages so the parameters are not so different. so you get cleaner water and healthier fishes :thumbsup: :grinyes:

unless the fish is a slow grower, wc goes with feeding. Especially if its the only fish in the tank.

water changes will increase the growth rate of slow growers :grinyes:

i was experimenting with water changes during my winter break and i notice an increase in size of my clown loaches :drool:

along with heavy feeding of coarse
 
Clean water means better growth, every other day seems excessive but I am lazy.
