I'll keep an eye on the timer and see how it works. It did its job again today so, so far, so good. Thanks for the heads up on it though.
The water in the tank is premixed RO water from a local store. I'll check the nitrates in some of the water I have leftover and see if it registers, but it shouldn't in RO water should it?
When battling the aiptasia, do you need a needle in the syringe or can you just shoot the boiling water right at it without? Is there no adverse effect of shooting Lemon juice in the tank? Also, if no lemon juice, could I use the lime juice that comes in those little plastic limes?
