300gal

if i had a bare 300 gal with an awsome filtration
with only 1 ten in silver 2 4' oscars
will i have to do alot of water changes within the first year
or maybe like once a month?

You should try to do them weekly. Change less water per week.

I would still do small water changes like 15%-20%.

well with 2 4' oscars I would be scared to put my hand in the water!!

But to the point try to do 15-25% weekly still.

still try minimum once every 10 days, with that kind of stocklist, you couldn't get away with just once a month

i would still do them once a week. some people stretch it to once every to weeks though.

The solution to polution is dilution... and that is a lot of dilution...

So yes you are correct that you will need to do less water changes... although doing a full water change schedule will not hurt anything...

The "risk" you will face is topping off evapolration. Since only pure H2O evaporates out... but you top off with tap water which contains metals & minerials... topping off with straight tap water will cause metals and minerals to increase. That's the theory, but I top off with tap water and have never had the slightest issue from doing so...

I would ask the people above to supply logical reasoning for their opinions...

I think monthly would be fine. Just remember that if you when change 25% of your water that is total system volume, so if you have a 300 gallon tank and a 100 gallon sump you would need to change 100 gallons of water. Where a 5-10% weekley water change would only be 20-40 gallons at a time.

Well depends on your feeding.... You can probably do once a month ONLY if you don't feed them often.

It may not be the 100% right way but if it were me i would watch the nitrate levels and once they hit 40ppm I would do a 50%er. It may be monthly and it may be weekly.
