Chewy is very easy to use for prescription drugs. We used it a lot for our dog. Finding a vet that will both give you the prescription for your fish and not require you to fill the prescription at their pharmacy usually requires a good vet/client relationship. Or maybe bribes.
0.68 is higher than most people like to keep their tanks but there are a lot of highly successful reefers that have higher levels than that. Every tank is different so it is hard to say 'lower this' or 'raise that'. Your tank is a unique ecosystem. What matters is how the livestock look and behave and how your rock/substrate is handling the bioload. If you sand is clean, you're not getting algae or bacterial outbreaks, and your livestock looks healthy, I wouldn't mess with it other than maybe make sure you aren't overfeeding..68just wasnt sure if that was a sign of a potential catastrophe
High PO4 is blamed sometimes for slow coral growth, which is probably true but I personally don't think high PO4 causes coral loss, at least not by itself, but then again I'm no expert so maybe someone else can chime in. I'd just watch my nutrient import, maybe increase nutrient export if it is easy to do but whatever you do, do it slowly. Rapid parameter changes are rarely good for a tank.
Bingo.
Yes I have. I like it a lot. I had it connected to the return pump for a month or so and tested it several times. It worked great. I've been doing some equipment changes on my tank so it is on a shelf at the moment.
