Will adding your base rock to my tank cause a new cycle? 

No, the rock is professionally cleaned and is devoid of any organics. Therefore, it will not cause a change in ammonia, nitrite or nitrate levels, the parameters normally associated with "the cycle". It doesn't have a bacterial population though either, and is not ready to support life by itself when it arrives, that will take some time in your aquarium for those populations to establish. In summary, it is safe to add to an established tank, just don't remove all the current rock until it has matured though; in a new tank it should be allowed to sit until a cycle has occured, you can start one by adding decaying organics to cause ammonia and kick start the process. FIsh flakes and cocktail shrimp are commonly used. 


When should I add a clean up crew to my tank? 

The tank must be cycled, and there should be some algae present for them to enjoy. Nitrates should be under 40ppm, and lower for certain inhabitants. Chitons and limpets for example should have nitrates under 10ppm consistently, as they become stressed when nitrates climb to 20ppm or greater. 


How do I request a later shipping date? 

Immediately before the "Confirm Order" button on our website you will find a comments box, you can request any shipping date you would like there and we will talk to you about it. However, weekends and holidays present some scheduling conflicts. No worries, you will receive human confirmation of all orders and a shipping day.

  • Cactus Caulerpa - #
  • Caulerpa mexicana
  • Caulerpa prolifera
  • Chaeto- # - edible, but very unlikely to be eaten if you have the chaeto we sell. Very, very, unlikely.
  • Dictyota ciliolata
  • Fern Caulerpa* - a favorite of French Angels
  • Manatee Grass #
  • Grape Caulerpa
  • Saw Blade Caulerpa
  • Heterosiphona sp*
  • Suction Cup Caulerpa
  • Oar Grass *
  • Botryocladia (Red Grape) * herbivorous fish and emerald crabs will likely eat the attractive bubbles this macro forms.
  • Green Gracilaria *
  • Halymenia *
  • Red Gracilaria*
  • Mermaid's Wine Glass*
  • Mermaid's Shot Glass*
  • Scroll Algae * - its light calcification works like fiber for tangs

Credit Card processing errors 15005, 15008 -
For security reasons, Paypal, our credit card processor, sends multiple error codes when a security feature is incorrect. If you receive one of these errors, it is because of one of 3 reasons:
  1. A 7 digit plus 4 zip code was used. It causes an error when it is security checked by our software. Please use only 7 digit zip codes. 
  2. The billing address is incorrect, or improperly formatted. Try to enter the address exactly as it appears on your credit card statement. 
  3. The credit card info, or 3 digit code was entered incorrectly.
*If you are still having trouble at this point, you can checkout using a credit still by selecting the Paypal payment method. When you get to the Paypal payment screen you will see a link that says "No Paypal account? Checkout as a guest with your credit card here".
