![]() The warranty and remedies set forth above are exclusive and in lieu of all others, whether oral or written, express or implied. Warranty is limited to repair or replacement, and does not cover fish loss, personal injury, property loss, or direct, incidental or consequential damage arising from the use of it. In either case, you will need to ship the entire unit back to us before we can ship a replacement. Costs for shipping back to us are not covered if you are not in the U.S., however we will pay for shipping back to you. Costs for shipping back to us are covered if you are in the U.S. The SURF2 and SURF2x come with a 6 month warranty: Warranty is for replacement or repair only not a refund. So while you may hear very muffled bubbling if the filter were next to your bed at night, you will hear nothing if there is any other activity occurring in your house. Lastly the path that air has to take to get out of the top requires the air to first go sideways towards the foam, and then upwards along the foam this allows the foam to absorb any remaining sound exactly the way foam absorbs sound in a studio. And the 1/2" (12 mm) thick LED lid is filled with super dense but flexible polyurethane, which absorbs more sound than a rigid structure would, and much more than a non-sealed structure would. This stops virtually all sound from going sideways. The thick and heavy gauge plastic growth container is coated internally by even thicker and heaver Green-Grabber textures, and is surrounded on the outside by 1" (2.5 cm) of closed cell polyethylene foam. As a matter of fact it's almost silent (the air pump is usually louder). Since the SURF2 and SURF2x do not touch the aquarium glass or sump glass, and since it's made of heavy material surrounded by foam, it is by far the quietest algae scrubber ever made. Sounds a bit backwards, but in the long term, you'll get a mature and stable tank faster if you manage it rather than putting a flamethrower on it.Īlso, see #15 here: Mything the Point, Part Three: Conclusion - Reefkeeping.Another feature which was highly requested was quiet operation. So in essence, you actually want the algae to grow in the tank somewhat. Many times the bacteria that are colonizing are also liberating the bound phosphates and then the algae grows from that (that's a simplified explanation but essentially that's the mechanism, at least in theory) If you scrub, you remove the periphyton and this delays your tank maturation as this has to rebuild. ![]() ![]() Use fingers if you can, then a toothbrush but you're not wanting to scrub - it's just that a toothbrush can snag algae and hang on to it better, so you're really just dragging it over the algae to pull it off without disturbing the surface of the rock where the bacteria is colonized (referred to as the periphyton) You can do this in the tank using a soft toothbrush, but take it one step at a time. To start off, you will want to pull the algae off the rocks. With reef tanks, there is a longer cycle of maturation so often techniques like this just push off the maturity of the tank.ĭepending on how old the tank is, this might just be a phase that will pass with time (and the scrubber will help). Click to expand.That works to an extent, but you're also going to eliminate the bacteria and essentially start over. ![]()
