55 gallon purchased used. 1 or 2' of crushed coral substrate (I didn't clean as tank was running) added 40 pounds of sand on top. 3 months later everything checks fine except nitrates 40 ppm. I removed bioballs from wet dry a month ago and at least 10 12 gallon or more water changes. Is it the old dirty crushed coral I need to get rid of?
Lost 2 clownfish 4 days apart. tore aquarium down today, removed live rock etc. they are nowhere to be found and dont see4 them on our floor? Ideas? they had been in tank for over 2 months and seemed fine. My blue and yellow tang seem fine. Could a clean up crew eat them that fast?
Thanks,
Gary
