Your local health department has mandated that you have a minimum of 4 turnovers between each float. The standard is generally 3 to 5 turnovers per cleaning cycle, and this number is often dictated by local health guidelines. The answer, therefore, is to filter for a longer period of time, giving the all of the water a better chance of getting through the system at least once.įor the recirculation method to be fully effective, we need to pump and filter the volume of the tank a number of times. This means that the filtered salt solution mixes back in with the solution that is still waiting to be filtered, making it hard to know when all of it has actually gone through the system. In this method, the solution goes right back into the float tank as it’s being pumped through the filtration system. Other float tanks use the “recirculation” method, where there is no holding tank. Once 100% of the solution has emptied into the holding tank, it can be refilled into the float tank this is typically known as the “reservoir” method, and lets you confidently know that all the water has gone through the filter in a single pass. Some float tanks pump the entire volume of their solution into an external holding tank after each float, passing it through the filter and the other sanitation equipment along the way. Whatever combination of sanitation methods are used to achieve this (UV, H2O2, ozone, bromine, etc.), each tank must also be filtered between floats.įloat tanks accomplish this in one of two ways. Because the solution isn’t drained after each float, a diligent approach to ensure the highest level of water sanitation is essential. One of the foundational realities of float tank sanitation is cleaning the solution between each float. They found that the density of the solution did, in fact, make a difference, and that their standard pool flow meter was quite a bit off from the real flow rate.Īs we will explore below, this can have some ramifications for float tank sanitation, and may make you want to change how long you run your pump between clients. We’ve recently gained some insight into that question on one piece of equipment in particular: the flow meter.Ī company called H2Flow, maker of the FlowVis (a flow meter that is widely used in the float industry), recently tested their device with float water. Float tanks tend to use a lot of parts borrowed from the pool and spa industry and, whenever that happens, it’s always important to question whether that pool part works accurately with our salt water solution.
