  • Bakki Temp loss?

    Hi all,my first post here. :roll: Have been lurking and learning for sometime now.
    Anyhow, can anybody tell me who has a Bakki Showered system running on an outside pond please tell me what kind of temp loss you have noticed since running one? Many thanks.

      Colin, don't even dream about using an unprotected bakki Shower in the UK.
      You'll either make yourself bankrupt with heating bills or freeze the koi to death.
      An enclosure needs making.

        No worries Maurice. Wasn't intending to do so. But out of interest with all the talk about them and the posssiblity of the chilling effect I was curious. If and when I can afford mine,I shall build an enclosure with a couple of rads in there to keep it all snug for the winter. :lol:

          bcak in the good old days before heat, when I ran my trickle tower in the spring, I was alwas 5 degrees lower than my cohorts with conventional systems.

            you can have a similar system.. drill holes in a plate of plastic put it on top of the tower, check that it delivers water evenly, splash water over any media holding a decent surface area, if worried about the temp slowing down the growth then build a port hole and use a vent fan to move the co2 out and pull oxygen in.
            remember not to block up the system with feed.
            remember that a filter takes time to be effective as it takes time to colonise with the different type of bacteria. give it 8 weeks, give it a chance.
            make a mesh filter to screen particluate and set up a self cleaning system on it.
            clean it to waste to the garden. then you can enjoy.

              bacci heat loss

              Hi colin
              how's things, I might be able to give you some figures first pond single shower flow rate over shower 4000 gallons this is covered by a tiled roof construction only open at the sides. The shower has a cover around it to stop wind chill. This is heated by oil, to 18 c degress all winter and the pond has polycarbonate 10 inch above water level, but have to say at the moment not the best fit it could be. And with this mild winter so far the cost for this 4000 gallon pond is around two pound aday.
              Pond 2 is 3500 gallon double shower with a flow of 4400 gallon a hour the bacci shower is covered with polycarbonate with the standard brackets, then polycarbonate over the pond completly. Now this pond surprisingly is heated by only a 2 kw heater fed from the skimmer by a 1500 gallon an hour pump.The pond is heated at the moment to 14.5 degrees it takes several hours to drop the 0.5 degrees for the heater to re heat the water. which then only takes the heater 3/4 to a hour to achieve 14.5 degrees. so pretty effective I think. So do your most to cover everything involved with the pond and I think the bacci shower is pretty economical. hope this helps mate keep in touch.

                I had no idea that there is a temperature loss in incorporating TT. Being in Hawaii (temperate climate), I'm assuming that the temperature swings are nothing to worry about. I think our largest temperture swings each day is between 60*F-75*(winter) 72*-88*(summer). Am I wrong in assuming this? Sorry, I'm not trying to brag about our weather (For all who are raving snow now).

                  Akai-San: If those are water temp swings, I'd be concerned. But, I expect those are air temps, in which case I doubt your water temps in a deep pond are varying more than 5-6 degrees on the "worst" days.

                        Bakki and TT work well because air has 250,000 times the saturerated oxygen content of water. If one cover those design the efficiency goes down. If you expose it or even using an electrical fan the effiency goes up .... but at the price of loosing water temperature.


                        Submerged media is not as effiency in oxidization but not too sensitive to ambient temperature. Mix and match in filtration types would produce the best combination result. Donald

                          my shower works great it is not a stand alone setup at the opisite end to the shower i have a vortex and a 5 bay filter since i put the shower on touch wood i have never had a problem with amonia or nitrite or 02 and with the poly carb cover i dont have much of a problem with temp drop maybe 1deg c.

                            I think the only concern I have is the degassing when a pond and filter is covered. As long as it can vent and still only flux one or two degrees I think your system will work just fine!

                            I loose two degres during the night and by midday it's back to where i have it set.

                              Akai, the evaporative cooling can be a benefit for koi in Hawaii because it takes the edge off our sub-tropical climate. My extreme winter low water temp is about 20-21C (68-70F) and the summer extreme high is about 26-27C (79-81F) in full sun, 24C in the shade.
