If it worked for two years, it should continue. You should clean it of excess film and then open the pump motor and inspect the impeller. Make sure the air passages are open and not clogged with calcium deposits. Although the SeaClone may not be the greatest, I remember the manufacturer has...

At the lowest tube where the pump pushes in water, lies the venturi. When bought new, they include a plastic key to unscrew it. A wide & dull butter knife is also the correct size tool.

If that actually is a MyReef sump, Andy is fixing to start using a CNC for cutting. That will definately put him in the powertool category. William Fisher

I owned the Berlin and had a terribly difficult time tuning it. The venturi can clog at the airway juncture. Drain the water out & try a pipecleaner in the airway or take out the venturi and soak it in vinegar if there is a calcium buildup. William Fisher

External pumps are available more powerful, transfer less heat to the water, take up less valuable real estate, and when they fail they do not pollute the water. However you usually need the sumptank drilled and a bulkhead installed. I really like the Blueline pumps at Champion Lighting or the...

Try grinding between two concrete blocks. Use gloves.

Halimedia is for the display tank as it is a calcium skeleton and needs the same environment as your corals. Chaeto brillopad algae is the favorite for the sump, can be fish food, seems stable, but is hard to anchor. I wrap it around dead acro branches to steady it in the water flow. I have not...

To help with C->F conversions: 30 degrees C. is 85 F. and just about too high for anything in a reef tank. Usally 27 C. or 80 F. is preferred. Atlanta's summers run 35 C. / 95 F. all day and 40 C. / 104 F. in the sun or under glass windows. Fortunately nearly everywhere is air-conditioned to a...

I live slightly more South and even though I tried using fans, it simply will not work when the room temperature exceeds the desired tank temperature. I do run my lamps starting at night when I come home and keep them off during the daytime heat. If you live in Singapore, I hope your home is...

My local lamp expert "Reeftanklighting" uses tempered glass in his fixture to attenuate the UV radiation. It really needs to be part of the hood. If I understand your question, you would not have the glass protection during tank service or feeding and would sunburn your arm. Actually any glass...

I have a unit from AquaSafe and the three years may be about right for replacing the RO membrane, but... It is really gallons of flow and how dirty the water has been, not time. The cheapest correct answer comes by using a TDS meter [total dissolved solids] and referencing the filter now to when...

I thought LA was always summer. When my Atlanta GA gas heat comes on it is still occasionally necessary to use the chiller to remove the heat from my halide lamps. If I lived North, I probably would disconnect to save pump energy and prevent stagnant water in the lines [which would happen if I...

Quite a few things make skimmers crazy. Any of the water conditioners that add the protective fish coat will, too high a pH as from a Kalkwasser overload, and of course any protein film. Just a guess but the sponges may have a manufacturing substance that needed to be rinsed out before use...

I am skeptical that a skimmer will fit into a 10 gallon with room for the main pump and the refugium as shown in your diagram, although the diagram does illustrate a proper sump. In the diagram, you would have all the tank's flow through the refugium and this might be excessive. Using a gravity...

Dosing pumps are designed to deliver set amounts of fluid over time, they are not made to run from a float switch. You adjust the milliliters being pumped to equal your 1-1/2 gallon evaporation. An electronic float switch could be wired as a fail-safe to cut power to the pump under the unusual...
