Reply To: Patio Garden: How often should you add more working solution?

[Andrew Stotzer]

Basically it needs the solution all the time. The only thing to think about is when it runs out will that hurt the pump to run empty. I think the pump manual warns you about this. But I always check by feeling the bottom of the top diffuser and soil for wetness. And if I’m not sure, I keep a 5 gal paint stur stick nearby and stick it in the hole to check.

But I let mine run out of solution. The pump is only running for 2 minutes at a time, so it probably won’t get hurt if that happens a few times. I also asked about how to replace the solution and was told the ladle it into the top like when you first set it up. I do that, but if I’m in a hurry, I will pour half of it through the hole.

Hope this helps..
