One of the first pieces of advice to be offered is this: have a back up supply of everything you may need to keep your hot tub well maintained and healthy. There are sometimes when you'll need to add chemicals or shock the water that if you were out of the supply, you may not be able to get to a dealership, and will have to forfeit a soak in the tub.
Thinking about a "shock treatment" when describing how it fits in with a hot tub may sound counter-productive and even dangerous but rest assured, if you have a hot tub, a shock treatment is a must-have. No matter how diligent you are about keeping your hot tub cleaned, everyone gets a little side-tracked every once in a while, and when your cleaning schedule is a little off, it will lead to a build-up of organic materials in the water. When you encounter the effects of material build-up, you will be thankful to have one or two shock treatments on hand, because by adding these will usually clear up any problems immediately. Again, I stress having one or two on hand at all times, so you don't have to post-pone a relaxing time in the hot tub because you need to run out to the store for the shock treatment products.
One feature on a hot tub that needs your attention is the safety cover. An inspection each month of the cover will ensure that you are aware of any wear and tear that may need to be addressed, which is a big safety issue, especially if there are children around. The other maintenance required of the safety cover is to be sure to wash it down, at least, once a month. Again, the longer your hot tub lasts, the more you'll get out of it and by these few ideas of cleaning and maintenance, you can be sure that it will be around for a long time.
Finally, when addressing hot tub maintenance to promote healthy clear water, clean the filter cartridge often, even if it is just by removing the cartridge and hosing it down with a garden hose; by doing this you will cut down on the maintenance needed to run an efficient hot tub. Hot tub maintenance would not be complete without some understanding of the need to completely drain the hot tub every three to four months.
Upgrading your hot tub
There is always the reason for changing your hot tub because you've changed your lifestyle or your decorating style has changed. There is no reason to have a gorgeous room that is modern-looking and beautiful only to have an out-of-date, out-of-style hot tub lurking in the corner. The hot tub addition to a room should always be to enhance the room, no detract from it. Meaning that if your style has changed, why not change your hot tub in order to continue the improvements?
Probably the best reason for upgrading your hot tub is that when the new models come out, there is almost always a form of energy savings and efficiency that has been addressed and improved. If you're finding that as the years pass it is costing more and more to keep the hot tub at a maintained temperature then it is definitely time to investigate the cost savings to compare to the upgrade cost and determine if the upgrade makes the most sense.
