Welcome to our forum.
Well for one Sundance is not on the verge of going under,and neither is Jacuzzi considering they own Sundance. Both the spas you mentioned are very nice and each have different features I like the jets in the Jacuzzi better from a feel standpoint also the 24hrs of filtration is nice compared to a main pump kicking off and on 50+ times a day when calling for heat.
lol not a fair or accurate statement 50 times a day to call for heat... NO...... ....it has 3 settings one of which will monitor the spa and SHOULD it call for heat will than heat however rarely will it need to do so.
One more question, the Jacuzzi dealer said he likes the 300 series better than the 400, thought the filtering was actually better. Any thoughts from the Jacuzzi people here?
Have there been many discussion here aboit maintaining tubs without chlorine?
