And honestly if anyone experiences chemistry swings i'd think it would be you since you change your water like once in a blue moon then do 80% . But your fish have always seemed healthy and well kept. Only out of curiosity would i bother checking when years of experience preceed any testing.
I do love that toy. But as Rickey said I did drop half of a C note on it however I never claimed to be tight or even responsible with money. I like buying stuff out of pure curiosity instead of *need*
as I stated in my reply I've got the same "toy"... sometimes ( not always)you get what you pay for... people spend alot of money on more useless items than a aquarium vac... running hoses across the house and down into the slop sink in my shop is not my idea of fun... that little "toy" makes short work of what otherwise would be a messy time consuming job..
Wise men speak when they have something to say...fools speak because they have to say something.
