SRC Member DUCADOS Posted April 22, 2010 SRC Member Share Posted April 22, 2010 Just check with the expert here. If I need top up water every alternate day due to evaporation,is water change still a must? I always top up around 40% of freshwater into my 3feet sump.

SRC Member tian1974 Posted April 22, 2010 SRC Member Share Posted April 22, 2010 since i dun do water change, i also topup with filtered water but i check my salinity and keep within the range of 1.024-1.026. edit: i dun topup 40% so much btw, hahaha Quote God Blessed all who appreciate His wonderful and beautiful creations. ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ my first reef aquarium 15jan2010 3x2x2ft EOS 10mm tank with sump//deltec sc2060 skimmer//arctica 1/10hp chiller maxpect g2 170w led//vortech mp40w wavemaker//eheim 1262 universal pump eheim compact+ 3000 chiller pump//caribsea ocean direct live sands 40lbs and other misc...

I always top up around 40% of freshwater into my 3feet sump. yes....top up water is to bring the salinity level back to normal as a result of evaporation. water change is to reduce nutrients and replenish vital trace elements Quote Link to comment Share on other sites More sharing options...

Water change and freshwater top up are two different things. Both have to be done. By the way, what do you mean by top up 40% of freshwater?

If that 40% is due to evaporation, then freshwater would be fine but I find that amount excessive. However, as Peter has mentioned, you will need to reduce excess nutrients from the water and putting back trace elements (from your saltwater mixture). So a water change would still be necessary to keep the tank running in good order (unless you are certain that tank conditions are excellent and you dose trace elements) Quote FOWLR Tank : 48"x24"x30" Sump: 36"x18"x20" Return Pump : Rio 32HF Skimmer: Reef Octopus DNW-110 Lighting: 150W MH Link to comment Share on other sites More sharing options...
SRC Member raydiative Posted April 22, 2010 SRC Member Share Posted April 22, 2010 as long as you are topping up the same amount of water that has evaporated from your tank it should not be any issue. You have to ensure that even after topping up your fresh water, you salinity is still relatively the same. Quote A man with a reef tank is a man with an empty wallet...

SRC Member LaW Posted April 22, 2010 SRC Member Share Posted April 22, 2010 topping up water is NOT changing water. sooner or later by doing that, ur salinity will be lower. and elements are not replenish. and i meant elements that are not measurable and you are not diluting whats bad in the water.

SRC Member teebs Posted April 22, 2010 SRC Member Share Posted April 22, 2010 Changing water means siphoning away your current tank water and replacing it with new NSW or salt mix. Topping up means water level drops due to evaporation and you add distilled or DI water to make up for the water lost through evaporation. I do have 1 question, how do you get 40% water loss in your sump tank through evaporation?

Lost by half is 50% ma so slightly lesser than half will be 40% lo if not mean lagi less which is 30% probably. Quote Some1 doesn't 1 2 do anything find an excuse,some1 1 2 do something find a mean!

xaine Posted April 22, 2010 Share Posted April 22, 2010 For a 3ft sump, that's alot of water even for 30%, unless you haven't topped up for a long duration. In that case, your tank's SG would have increased by quite a bit.

Changing will required discharging of old water then replenished new right? yeah you are right already. just think it this way, top-up water ==> maintaing water level and salinit. changing water: ==> diluting waste and replenishing whats good.

I'm very sure that even without a chiller, there couldn't be that much evaporation from your sump.
