Tridacna maxima Ultra Blue 12cm

£189.95

 

Tridacna maxima is a popular giant clam for reef aquariums. After many years of good care, they may reach sizes of 20-30 cm. Their colours are caused by refraction, similar to a butterfly’s wings, and they vary drastically with the angle of view. They look brightest when viewed from above.

In the home aquarium, the Maxima Clams require intense lighting to thrive as they contain the symbiotic algae called zooxanthellae, and receive the majority of their nutrition from the light through photosynthesis. Smaller T. maxima that are 2” or less in size are much more sensitive to very intense lighting as their membrane is much thinner than larger specimens. For this reason, care should be taken to properly photo-adapt them to the existing reef aquarium lighting in a similar manner to newly introduced stony and soft corals.

When adopting a new Maxima Clam to very intense lighting, it is ideal to set them on a small rock or in a plastic dish with the coarse substrate at the bottom of the aquarium. Over time the clam can then be slowly moved up higher in the aquarium.

Tridacna maxima Ultra + Green Acropora

Tridacna maxima clams are one of the easier clams to keep and make a great choice for a beginner. They are a good conversation piece and are sure to dazzle you with their beauty. Do not house with Triggers, Puffers, and aggressive predatory Wrasses as they cannot seem to resist picking at clams.

Place the Tridacna maxima clam in the sand, or in a rock crevice, in the lower half of the aquarium where they will receive moderate currents and moderate lighting.

Although symbiotic algae called zooxanthellae hosted within them supply most of their nutritional requirements through photosynthesis they do benefit from supplemental feedings Phytoplankton.

Target feeding gets the clam fed using less food while keeping your nitrates and phosphates lower.

Tridacna maxima clams require moderate water flow and moderate lighting (PAR 180-300). T5’s, Metal Halides, or LED’s can all grow Derasa Clams when the proper PAR levels are provided. We recommend a 14-20K colour spectrum for best colouration.

Care Level: Easy
Lighting Requirements: Moderate (PAR 180-300)
Water Flow: Moderate
Aggressiveness: Peaceful
Range: Indo Pacific
Family: Tridacna maxima
Water Conditions: 75-80° F; sg 1.024-1.026 (1.025 is ideal); pH 8.1-8.4 Ca 420-440 ppm, Alk 8-9.5 dKH, Mg 1260-1350, Nitrates <10ppm, Phosphates, < .10ppm

It is important that proper calcium (420-440 ppm), alkalinity (8-9.5 dkh – run it 7-8 if you are carbon dosing) , and magnesium levels (1260-1350 ppm) are maintained. Raising magnesium levels gradually up to 1400-1600 ppm can help to combat algae outbreaks, just keep CA and Alk in line as you raise the Mg. Nitrates should be below 10 ppm and phosphates should be below .10 ppm.

 

We recommend doing a water change when Nitrate levels rise to 10 ppm. It is important to replace your phosphate media when phosphates rise to .10 ppm. Media Reactors make the most efficient use of your phosphate media by fluidizing it.

Fraggle Reef uses and recommends dosing pumps to automate the dosing of additives and keep your levels more constant.

 

A dosing pump can alleviate the chore of manually dosing your aquarium with Ca, Alk, & Mg 2,3, or 4 times per week and will benefit your aquarium by keeping your levels constant through frequent small additions of Ca, Alk, & Mg.

 

Our tanks all progressed when we switched from 3 manual dosing per week to 70 automatic dosing per week and we got a lot more work done.
