SunSun HW-303B First Impressions

This thing is a beast.

The bacteria eats the nitrates in the water to help keep it clean. I had to lower the surface by 3 inches to get sufficient agitation. Lift the sticking wheel outuse a Q-tip to clean the slots where the wheel rests. Just rinse them out once a month, don't throw that beneficial bacteria away. BUT after some YouTube research I was able to fix the noise issue. I wasn't able to fill my tank fully because there was little to no surface agitation. This is a good choice if you're tired of cleaning your turtle tank all the time.

SunSun HW-303B Final Thoughts

I was to tire to fix it.

I returned the Aqua Clear 70 and promptly received a replacement. The bacteria eats the nitrates in the water to help keep it clean. Therefore, you wouldnt have 2 filters running. Following morning it was running quietly. All in all, I highly recommend this filter and I'm a extremely happy customer! I'm currently in the process of receiving another replacement on that model. I have always used Marineland filters and been happy with them and their quality.
