Water Bath Circulation

Recommended Posts

I am thinking about installing a water bath in my 6ft greenhouse to house my Sarracenia and VFT, so the water doesn't become stagnant and to reduce algae. Is it worth putting in a small water circulation pump to gently move the water or will Sphagnum moss stop the algae and keep the water clean. Any help and advice would be appreciated.

How are you replenishing the water in the bath?

They'll be fine in stagnant water. Algae on the surface isn't an issue.

I currently have a grow bag tray which I replenish the water level manually. This tray will be too small very soon as my collection increases, so I was going to build a bigger tray/bath so that I can utilise the whole side of one side of the greenhouse. The the new bath would have a overflow into a holding tank underneath the bath. The water being pumped back up and utilising an aquarium spray bar to create a gentle flow.

Is Sphagnum happier with a slight water flow or still?

It's fine with either option. Sometimes people have a moving water setup for darlingtonia and sphagnum moss

I think it's a positive concept. 

I've also considered growing something vigorous in the sump (water hyacinth?) to reduce nutrient levels, and having an in line UV steriliser to reduce pathogen levels in the water. 

If the sump was large enough it might also provide some temperature buffering. 

And you would probably grow some great Disa orchids
