Evaporation Top-offs

[Jasondonovan]

Top up with just water not saltwater.

bro, if you are keeping fish only tank and hardy fish (damsel, clown), i think tab water (dechlorined) is fine (in Singapore context). I have tried this and so far so good.

Newbie here too, riding on this thread and my first post too! So does it mean you mix tap water with one of those Anti Chlorine, Anti Chloramine and Anti Ammonia treatment solutions is good enough to be used for top up? How about for water changes?

There was a thread on our sg tap water before, there are phosphates and heavy metals present, apart from chlorine. In which we all try to remove as much as possible in a reef tank. Phosphates trigger algae growth. And chlorine is pretty much poisonous to anything in the water. Yes tap water is free, but at the expense of your livestock's well being. Kudos!

"i do it every day."

Normally i'll do top-ups every 2 days with distilled water bought from NTUC.

[captainaquarium]

i should be more often

[iczboi]

I am also using a fan for my tank. So it is advisable that we just use normal tap water to topup the evaporated water?

[Guest diaosinan]

once a week

[Guest diaosinan]

once a day man

[chrislwp]

Every 2 to 3 days with 1/2 pail of kalkwasser mixed water for a 150gal tank, dipping overnight.

[Guest diaosinan]

as often as possible

Topup happens every hour for me. Using dosing pump with highly diluted sodium bicarbonate. So it acts as my topup and Kh dosing.

What's wrong with tap water for reef other than the nitrate and phosphate?

[CFOh]

chlorine from tap water is more concern for fowlr... compare to silica,nitrate or phosphate.. Cheers..

Dechlorinator should easily fix that

Yes... likewise with nitrate or phosphates has their own methods. But if the question asking whats wrong or potential fish killer using tapwater.. then I will suggested Chlorine. Cheers..

Other than that, tapwater for top up is fine? Would tapwater top up add that much nitrate and phosphate into a system?

Base on WHO, Nitrate can be 50 but generally <20 & PO4 No requirement but generally <0.10. Cheers..

Singapore average? Can't seem to find publications on that. Should have grabbed boxes of newater during ndp, =(

i used tap water , drip from a bott with a pin puncture at the bottom of the bott (diy), with no problem to fish n corals. But all my stuff r hardy. If u keep sensitive stuff then u gotta consider using filtered, RO or distilled or Newater

I add cal, sodium bi, n magnesium together in the top up

cheers
