So the is high,what do i do about bring it down,thanks |
Here's what I recommend.
1. Leave the tank water completely alone. The Alk and Mg will come down on their own just from the Coralline Algae and the animals using it;
3. Reduce the MH lighting. For example, set the MH timer to come on at 4PM and go off at 8PM, the hours when most people are home and viewing the tank. Leave the t-5 lights coming on and off as usual and when it's time to replace the 6500 Kelvin MH bulb, check if the ballast will handle a 150 Watt and make it a 10,000 K or 14,000 K bulb;
4. Unplug and remove the chiller because with less MH lighting and a lower baseline temperature, it will no longer be needed;
5. Remove and replace the API Bio-chem-zorb with ordinary AC, that resin is not so good for a reef;
6 When the the Poly Filter is spent, do not replace it, but keep any unused pads for special needs.
Aloha,

As promised, below are Jacques Cousteau pics of the predominant blue lighting provided by the sun in the depths of the ocean. LPS and Soft Coral are normally found living at 10-60 ft. Clams have even been found at 60 ft. because they need food as much as they need light. Under the 250 W MH more phytoplanton grew which fed the clam. I suggest
Brine Shrimp Direct(BSD) Tahitian Blend Algae Paste for feeding clams. We are so lucky that BSD is in Ogden.
