Water change how often?

[Rusty91]

Hi,
I‘ve read that fish will grow better if you perform a lot of water changes. Currently I have a 4 inch red devil solo in a 107 gallons. At the moment i change about 60% a week. Sometimes twice a week if I have the time. I think that should be fine to get a good growth on my cichlid. What are your opinions of that? How often do you change?
Would appreciate some experience from you guys….

When I had my red devil in a 75 gallon I was doing 80% water changes every 3 days,granted i only had it for a very short period of time but it grew quite a bit during that time. It's all about dilution IMO.

Some members do fin level weekly wc's but 60% a week is good.

Also keep filter, sump and substrate free of waste. Feed high quality food.

Thanks for the advice.?
I feed hikari and nls, because it seems like many of you guys use that.

IMO, A solo juvenile Red Devil kept in a 100 + gal. tank, should do fine with one weekly 50% WC as long as appropriate filtration is provided, no overfeeding is occurring & a deep gravel substrate is present.

50% weekly should suffice, assuming that you’re not over-feeding and/or have adequate filtration.

For optimum growth rate you need to tick three basic boxes...

1. Suitably sized tank to start off with, which for a 4" fish, I think you've got your first tick.

2. Quality varied diet. Hikari and NLS aren't a bad starting point, second tick.

3. Keep your nitrate as low as possible, and I mean low, no greater than 5ppm. I doubt very much, unless you are overfeeding or are very lazy at maintenance time, that your bio load is high with that lone fish anyway. So for tick number 3 you need to establish your nitrate creep, and perform water changes to keep it very low.

Genes may also play a part, but there's little you can do about that.

i have multi test strips and use them on my 55 gallon, they always say its clean but gunk still builds up at the bottom
for me the water changes are mostly to make it look nicer
