ReefMat how long does your roll last?

[FernBluffReef]

RM1200 on an RS525 averaging about 30” a day, well stocked - so just under 2 months

RM500 on an RS170 averaging about 9” a day, lightly stocked - so several months

I have a RM 500 on a Reefer 350. Averaging 160cm (62") per day. I'm sick of changing a roll every 10 days or so and thinking about going back to socks.

Go through “5 a day with my reefmat 1200 on the 235 gallon reef.

Slow your drainage it will last so much longer.

That's a lot. What is your settings at? How much do you have it set to uptake each time? On our 130g total system, our reef mat 500 is now averaging 15" a day.

Also how fast is your sump return set or how much are your filtering. All can come into play on how much it uses. But I think 62" is something in the settings probably.

How dirty are your rolls when you replace them?

This is true.
One other thing is maybe try raising it like I did mine with some cardboard. Since yours is a 500, I don’t believe you will need to worry too much about excessive force on the roll, but this can be a problem with the 1200.

Originally i had a Reefmat 500 on my 125g w ( 40g sump). Rolls would last about 3 weeks. Went to a 1200 in June and I still on my first roll ( have about 10' left on it). The 1200 roll is solid green/brown with what was filtered out. The 500 roll was always splotchy even when i had the flow low.
