how much does roll does your reefmat use per day (you can see in the app). As long as its not a tiny amount you're still better off with the reefmat then filter socks. Mine uses ~30 inches per day which i feel like is a full cycle of fresh material. Basically like changing filter socks everyday. I think your advance length is way too long.Yeah you said it. So here's my issue, if you set the reefmat to the slowest advance setting, then youight as well not be using a Reefmat because the dirty water flowing through the dirty fleece will cause nutrients and decaying food to increase greatly.
I have a full Acropora system and can't have that situation. I have it set to advance 1.2 to 1.4 inches. I completely get what you're saying and you may very well be right. My complaint is having to bandaid issues from a poorly designed system.
Yes, my flow is very high. I have 4 Nero 7s and they are set to basically Reef Crest mode, two on the back wall and two in the sides of the tank.
They run in steady mode at night and I still have issues. It's the craziest thing I've ever seen. The return chamber is the only one that drains. The Reefmat area and the Skimmer chamber are full. I have to tell you, if I knew this was an issue before hand, I would have went with another system. It's no joke, every hour or two I'm having to adjust and re-adjust that stupid valve.
Yeah, I'm a bit frustrated at this point. I appreciate your help and support.
I would also try changing your nero settings to be the same mode as during the day since your problems seem to be at night.
