Top-up Question

[Omega]

Hi there guys,

Ok I have seen that some of my water has evaporated, I do have clean water to top-up with and the question is-

Do I have to add the water over a certain period of time like on cup every ten minutes or can i just fill it to the old level

TIA

I top off once a day. My sump is clear plastic and I used a black Sharpie pen to mark a line where the proper level should be. I just add water to that line every day.

HTH.

But I dont have a sump I have a main tank with a canister filter so how do I do this now?

Same method applies. I would decide where your ideal level is and mark it. Depending on how bg your tank is, you can still top off once a day. The smaller the tank, the more often I would add water.

In my 120, I lose 1-2 gallons of water a day. Seems like alot, but not that significant in relation to the total water volume (120 galllons in the main tank and 15 gallons in the sump.)

So if you had a smaller tank, you may want to do it twice a day.

Just my $ .02 cents.

Thanks for all the quick advice

The main issue is rapid change in salinity. It depends on what you're keeping, but a rough guideline I've read is to avoid decreasing the salinity more than 0.001 with each addition of freshwater. So if you notice a significant drop in water level, it's a good idea to add a portion, check salinity, repeat... I usually check the water level of my 20g 3x a day (before I leave for work, when I get home, and before I go to bed), and I pour the top-off in a slow stream into my HOB. A cup every 10 minutes is unnecessay and would be a huge pain.
