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. Costs for shipping back to us are not covered you will need to ship the entire unit back to us before we can ship a replacement. This RAIN4 comes with a 1 year warranty: Warranty is for replacement or repair only not a refund. Freshwater aquariums, which may only need alkalinity (hardness) to be maintained, may get enough alkalinity from just doing evaporation top-offs with tap water from your sink. So if you wish to reduce or eliminate water changes, and have stoney corals, you will need to supplement any calcium, alkalinity, magnesium or strontium that you were depending on water changes for. However, this filter (and algae in general) do not supply calcium, alkalinity, magnesium or strontium. When algae grow in the filter, they consume nitrate, nitrite, phosphate, ammonia/ammonium, metals, CO2, and some toxins so it’s just a matter of growing enough algae inside the filter to do the filtering you need, compared to how many nutrients you are putting into the tank with the food you feed (that is why the RAIN filter is sized for a certain amount of feeding per day). * Water Changes: If you have been doing water changes to reduce nitrate, phosphate, or nuisance algae, then an algae scrubber filter will greatly reduce the need for them and may possibly eliminate them. But generally, algae need dark time to rest, so plan on getting a timer, especially on a new tank with low nutrients. However you can try 24 hours of light (no timer) if you like because sometimes it does work well in saltwater with high measured nutrients such as more than 1.0 ppm phosphate. The GEM5 lights can be put on a timer so that they stay on for part of the day, and off for the rest of the day, to possibly improve growth and filtering. Do not ever try this technique with other waterfall algae scrubbers because it would be a serious electrical hazard. With the screen submerged like this, it can last for several days with no flow or light. The GEM5 lights will not be harmed at all because they are designed for underwater use. If you commonly have power outages, all other waterfall scrubbers will dry out after a few hours, but you can prepare for and prevent this with your RAIN4 scrubber by placing it low enough in your sump (even slightly underwater if needed) so that when the power goes out the water level in the sump will rise up high enough to keep the screen under water.
