Is it necessary to do water change after cycling?

[abflug22]

Cycled my 4ft x 2 x 2.5 for abt 6wks with abt 80kg cured LR, 100kg cured sand. Din put in the mkt prawn.

started RM beckette and FR from 2nd wk onwards.

Tested zero for ammonia after wk3, no nitrite test kit so waited for 1-2wks, approx 7th wk, tested nitrate mabbe <3-5ppm (apologies if wrong unit of measurement) using salifert kit. started RM beckette and FR from 2nd wk onwards.

now contemplating to do a water change. how many % change? subsequent changes how many %?

Pls advise

no harm doing a water change for u right now before u add any LS

frequent changing of water is good.

about 10% weekly

about 10-15% fortnightly

about 15-25% a month.

these are the recommended values.

its actually up to a person's preference.

for me, 25% per month.

I prefer to do some amounts, maybe 10% per week rather than 40% every month...

Water changes is always good provided the new salt mix is the same parameters.

Regular water changes is liken to opening a window and bringing fresh air into a stale room.

No harm but good (provided you don't change the water parameters drastically).
