A canister fitler can be just as bad as the bio wheel. I would have gone with a sump! Anything with a filter pad or is designed to trap waste will/can cause a nitrate problem.
I would empty the tank and change the substrate all at one time and use that opportunity to remove the damsels before the tank is well established and you are trying to figure out how to catch them.
I would say cheato in a sump would aid in getting rid or nitrates. I have never heard of clams having any effect on nitrates and i am not a believe in nitrate sponges.
Make sure you are using additional PHs for more circulation. As Phishface said your filter might be rated for 100 gallon but you still want your tanks water to be circulated 10-20Xs more per hour.
There are 2 things that I see right away that could be the cause of your nitrate problem The first is the crushed coral substrate and the 2nd being the 405 canister fiter. A sand substrate stays cleaner and does not harbor nitrates the way crushed coral can. I had the same thing in my 220 and...
Panther groupers grow large and they do it pretty fast. Not a reef fish by any stretch......They also get ugly when they get bigger and lose there black/white color.
you will get as many different answers as there are memers. I only use mexican turbo snails. I do have a few hermits left but once they are gone no more hermits. Hermits love to wear the turbo snail shells and pound for pound I think snails are the way to go.........
I am of the belief that ich is always present in your tank and under the right conditions fish will get ich. I understand tangs are a favorite due to there small scales. Regarding kick ick, I have used it in the past with success but it wasn't because I followed the directions. I doses at...
Everyone seem to do it a little different and as far as i can tell there are no set rules. Some people change water in large amounts once a month while other change small amounts every week. I have a 220 and change out about 10 gallons a week. I turn off the pumps, syphon water out and then...
