Red sea Max Nano 225 Thin-Mesh Filter Bag (x2)

I was using the 100's for the past 4 months but was getting sick of having to change them morning and night. Yes twice a day lol. Its a good job they are reusable lol. This was messing with the ATO. Where the sock chamber is the water was slowing down causing the water to use the overflow this in turn then causes the ATO to put more RO in to compensate the slow down so was making my tank have minor salinity fluctuations. I only put these 225's in yesterday, I checked last night before bed and still running through fine, I checked again this morning and still running through perfectly. The water still has perfect clarity so I'm pretty happy and it'll make my tank have better stability from here on. Fingers crossed.
