I seem to have started a very big discussion here
Cranberry.....if someone doesn't have an auto top off unit, as I don't, the water will fluctuate in the sump every day unless you fill it every day manually and have an effect on any skimmer, correct?
Discussions are gooood. Everyone has different opinions based on their own experiences. I'm not saying ASMs are bad, there's been a lot of good reviews, that's why we bought one. It's just giving me a hard time and I'm not a skimmer noob. I like my ER best out of the ones I have.
It all depends on how you have your sump setup as to whether or not the water will fluctuate in the area you have the skimmer. I have baffles and a pump bay, so the water flucuates there, not in the main sump area. For me, if the pump bay water drops an inch, the ATO cuts in. If you have a pump bay, your water should not flucuate, even if you do manual topoffs.
But evaporation isn't the only thing that changes water level in your sump. Even if I stick my arm in the tank, the water in the display will be displaced to the sump momentarily until I remove my arm. I can't even do this without messing up the ASM... it's THAT kind of flucuation that I'm really talking about... adding a rock... that sort of thing.
Do you have a pump bay?
