Top off

I just started topping off because i had to get rid of my glass top. How do other people top off. I am afraid of killing corals because of the mixing water in the tank. If you dont have a sump where would you top off in the tank?

As long as you top off frequently, it shouldn't be too big of a concern. Do it away from corals and and fish. As a general rule, the more a solute is like a solvent, the quicker it dissolves. Since fresh water is very similar to salt water, it dissolves very quickly.

I top off in the sump.. About 5 gallons a day or so.. Its added slowly though so there is little chance of shock, even with the temp being so different..

just to be sure...you only top off with fresh RO water, not saltwater. Pour water right in the top of the tank...if you have MH lights be careful, a tiny drop of water will burst the bulb.

I have a container of RO water on the second floor with a drip line running to the tank. It just takes a little time to get the drip equal to the evaporation rate.

Do you have a skimmer or anything? If so I would suggest putting the water in at that point to help with the mixing.

Top off frequently and you won't have a problem with overwhelming your system with too much fresh water at one time.

You should put an float valve on that

Why? With float valve mortality rates being what they are, I run a geater risk of flooding my living room. I good drip valve is a couple bucks and only allows "X" amount of fluid to pass through. If I wanted to add a float valve, I would just use a PH and place it in a 10 gal bucket beside the tank. Plumbing from an RO unit is not feasible in my house. My method is cheap as dirt and practically fail safe.
