Helpful plumbing tip for Dolphin AmpMaster Pumps and other low RPM pumps
2. Always us the same size or larger piping on the return line –to act as a loop distribution manifold. Add reducing tees wherever you need a smaller return line, (control each smaller line with a ball valve), (Plumb the distribution manifold keeping in mind the shorter the small return line the more efficient your system will be). Use enough small lines to equal 80 to 100% of the area of the pump discharge opening. To do this, take the inside diameter of the pump discharge, divide by two, multiply by itself (square it) and then multiply by 3.14. Do the same for the smaller line you intend to use and divide the answer for the pump discharge by the answer for the smaller line. This will give you the number of those smaller lines to use.

Helpful plumbing tip for Dolphin AmpMaster Pumps and other low RPM pumps
1. On intakes, use the same, or one size larger piping as the intake port on your pump. Install a full port ball or gate valve right before and right after the pump. If you have to use a 90 degree fitting, use a DWV sweep fitting to minimize intake turbulence. Closed loop manifolds, (a return which returns to itself) are the most efficient for maximum flow volume.

Tip #19: Maintain your reverse osmosis system by replaceing the sediment and carbon pre-filter every 6 months under normal use. Replace the membrane and carbon post-filter every other year. This will ensure optimal water quality.

Tip #15: Additives should not be dose, then test again 12-24 hours later. It is better to slowly add the correct amount then to overdose and possibly cause an algae bloom.

Catalog Tip #14
Tip #14: Over time, a light bulb’s color spectrum will degrade to a lower kelvin rating. Corals require the proper lighting spectrum to enable symbiotic algae living withing coral tissues to assimilate light into nutrients. To prevent coral die off and unwanted algae growth, replace light bulbs every 12-14 months for power compact and metal halide bulbs and every 10-12 months for flourescent and VHO bulbs. This will ensure the proper lighting spectrum is available for your corals

Catalog Tip #13
Tip #13: What is HQI? The term “HQI” has become synonymous with double ended metal halide bulbs, but is in fact a pattented method of bulb construction devoloped by a German manufacturer that can be translated to “metal halide”. In most cases, double ended bulbs are mistakenly referred to as “HQI”. A true HQI bulb is designed to be ignited by a special ballast for optimal results.

Tip #12: For optimal light distribution, place the metal halides at two foot intervals above the aquarium. For aquariums up to 24” in depth, we recommend 175 watt bulbs. For aquariums 24” thru 36” deep use 250 watt bulbs. For aquariums 36” thru 48” deep use 400 watt bulbs. For aquariums deeper than 48” use 1000 watt bulbs.
