am already doing a regularwater change abt 20% every two weeks or so.....lighting is 2 x 35w high lites with reflectors:
High-Lite refers to the new light technology by JUWEL Aquarium. It combines the existing tube lengths of the T8 with the new bright T5 technology.
High-Lite Light units run with unique tubes which fit the full length of the aquarium for maximum illumination.
The High-Lite light unit is 92 cm long and can be equipped with 2 Tubes 742 mm / 35 Watt. Optional special JUWEL Reflectors will double the light output of the system.
as for the rockmover wrasse....i have already been offered a swop by LFS if he causes trouble in the tank..BUT he is my favourite fish...he has so much character...YES he tosses things around and digs up the whole tank just after i set it mind you but i lie to myself saying he is actually doing me a fav by tossing the soil anyway allowing filter to work better and catches all the bugs hiding
in fact My Yello(when bought) now Choclate yellow surgeon does more damage ...nibbles on my polyps and tube worms and is a bully ,,,,,Thanks for the warning guys but surely u all have gotten a fish u know is wrong but wanna try and make it work regardless.... IF he really does cause hell i will take LFS up on their offer
BTW Polyps opened up again when placed them higher to lights with more flow ...they happy again and greener than ever...go figure
