Water change/Evaporation

JackJake · 02/28/2008, 11:31 AM

I have a 29 galllon. The water evaporates at least 10% every week and a half. my question is do I still need to do water changes or just replace the water that has evaporated. also, I was told that when replacing the water, that I dont have to mix salt with it. because the water that evaporates has no salt in it, there is no need to add salt mixed water, just freshwater. is that true?

Replacing evaporated water with pure fresh water is necessary, but does not alter the need for water changes where you swap clean salt water for tank salt water. Water changes import and export things that adding fresh water does not.

true..

Still do water changes though

Salt stays in, water needs to be rodi fresh water for top offs.

Yes you still need waterchanges, they remove excess nutrients and replace used up trace elements.

JackJake · 02/28/2008, 11:36 AM

also another little question. If I were to get a new light that put out 130 watts, would that be sufficient to keep certain corals and anenomies. Or maybe, what is the recommended wattage to keep these creatures? if i got the 130 watt, i could possible also use the light that I currently have on it(Reef Sun 50/50) and possible be efficient. Thanks

I have a BioCube 14....I do top offs every day......however I also do a 20% water change every week. Thats how it stays looking like this

rodi? does that stand for something or was it a typo?

Revese Osmosis De-Ionized water, its the pure water that most of us use in our tanks

JackJake · 02/28/2008, 12:01 PM

its all good newfish. just gonna attract more people to answer my questions. nothin but love. your tank is nice though, prestine conditions

an411 · 02/28/2008, 12:11 PM

I do not think that you can compare what an ro/di does to a brita filter. I mean I guess its better then straight tap water. But if money allows I would recommend getting even the cheapest ro/di the budget allows.

Jackjake,

You need to get some photos in your gallery so we can see them.

Happy reefin

JackJake · 02/28/2008, 12:34 PM

that's about it. sorry the pics are a little blurry, makes my tank look cloudy. but thats all I have so far, only had the fish in there about 4 weeks. plan on getting a better lighting system next week, and more LR in the future. I just got a emerald crab and he's takin host to the condy already. I know I have alot of work to do. i'm in the process of getting rid of my freshwater oscar tank so i can dedicate more time and money to my salt water. any comments or suggestions are welcome. thanks for looking

The inlet to the ro/di unit is tap water, it can be hoocked up a # of ways, from the faucet with an adapter, a pierce valve on a cold water copper line after the water softner if you have one, a unit consist of a sediment prefilter to get small particles out, then a carbon block filter to get out clorine/chlorimine and a few other things, then the water goes thru a reverse osmosis membrane, at that point it should almost pure, about 3 total dissovled solids, TDS for short, then it goes thru the DI, it is a resin that attaches the rest of the ions in the water too, after that the water should have 0 TDS, I for got what DI stands for. No impurities, chlorine, phosphates, ect, use it for top off/make up water from evaperation and to mix with your salt for water changes.
