    This new install of a RAIN4 in a saltwater sump, with the LED light dome lid removed, shows:

    o Good flow of water across the whole bottom of the screen; less is ok but the whole bottom of the screen should have water flowing off of it.

    o The black tray is level with the sump waterline; this eliminates all sound when the dome lid in put back on. The tray can be lowered even further so the screen is below the waterline, so that the water does not fall off the screen and instead flows smoothly downwards.

    o The screen can be slid forward (after removing the red cap) and out of the sump with the water still flowing, and without disassembling anything.

    o Growth can be seen easily, and hand-removed easily, without disassembling anything.

    o The black tray can be easily lifted up off the pole mount and taken to a sink for brushing.

    o If power goes out for a few days, the black tray can be lifted up and set down in the water, to keep the algae alive for over a week.

    Happy Scrubbing

    This RAIN4 is ready for a cleaning/harvesting, and shows how low it can go in the sump water, in this case the tray is all under water. This can be done to save vertical space, or to make it dead silent, since the water draining from the tray does not fall at all and thus does not need a drain pipe attached to it.

    Another RAIN4 filling in, with the tray under water (see the right side) which allows dead silent operation safely because the GEM5 lights are submersible. This particular RAIN4 needs the screen and tray brushed clean.

    New air cooling vents on the sides of the RAIN4. The waterfalling water does a lot of the cooling inside the dome cover, but if the water is turned off these vents take over and allow cool air to enter the dome at the bottom and flow upwards over the GEM5 lights. The shape of the vent covers also blocks almost all red light from getting out.

    The RAIN4 (tm) goes down down down into the sump, saving lots of space, and can go down under water if needed.

    This RAIN4 (tm) Green Grabber® screen is almost filled in. Note the coralline on the bottom tray, which is not a problem to clean because of how much open space you have when the LED dome lid is removed. And it might look like the tray is setting on a table, but it's actually still in the sump, sitting at water level which makes zero sound.

    This RAIN4 is getting started, and looks like it has 1 light running in the middle. The dark slime (from high nutrients in the water) is holding on to the Green Grabber screen as best it can, but still needs cleaning/harvesting every 3 or 4 days until lighter green hair growth can get rooted in the screen. Waterfalls are no match with bubble upflows when dealing with slippery dark slime, but the porous 3D printed screen will hold more of the growth than the old style knitting canvas screens will. This slime situation is a great application for our new Slime and Heavy Growth screens.

    This is an established RAIN4 standard stock flat screen, showing the newer hang-tabs at the top, ready to drop into the display to feed the fish.
