penguinexdeus Posted October 13, 2020 Share Posted October 13, 2020 Set up a 40 breeder a few days ago using the 300W Fluval E Heater and two of the Hygger double sponge filters (fine sponge). I don't seem to be getting a lot of flow placing the heater next to the sponge filters (never had a problem with a more coarse sponge). Kept getting the low flow alarm on the heater when it was vertical next to a filter. I put the heater at a 45 degree angle now between the two filters and directed the 90 degree filter tube output towards the heater. I don't have the low flow alarm anymore but the tank is struggling to get to temperature. Can't seem to get it above 76F and I want it around 78F. Any suggestions? I want to use these filters since they suction to the back wall and leave me some floor space & i plan on breeding a few things in the tank. Filters aren't dirty since nothing in tank at the moment except substrate and some plants. Link to comment Share on other sites More sharing options...
