im having trouble figuring out why all of my fish are breathing very fast,the salt level was a little high and i brought that down,i had the water tested and everything was fine,the nitrates were a little high and i fixed that,there are no dead fish in the tank or anything,i have a 125gl tank and my fluval 405filter seems like its not pumping water out as fast as it was could that be the problem and if so are there any parts i can replace on it. thank you
The problem seems to be that the fish are being very stressed. This can cause major problems. This should clear up in a few hours but if it doesn't send me a Private Message and i'd be happy to help. Just be sure to provide water quality details
I highly advise against this concept. The benefit of a public forum is that you can get the advice and experience of others who are capable. Using the Private Message feature restricts your ability to learn from multiple sources.
remove the fluval. these filters are great on a freshwater setup but on a marine tank they do more harm then good.
im going to guess that the filter has built up excess nutrients which caused your high nitrate issues. i need more information on the tank, saying your water is "good" tells me nothing. what exactly is "good?" please post your exact water parameters, ammonia, nitrite, nitrate, pH, temp, salinity ( and what you used to test it ) mag, ca, and alk. if you dont have your own test kits for these i strongly suggest picking up these. liquid kits are far more accurate then strips.
what livestock, other filtration? skimmer?(brand/model) sump? flow? lights? depth of substrate? kind of substrate? how long has the tank been set up? and everything and anything else you can include.
Just a thought, is the water being aerated? Do you have a power head breaking the water surface allowing O2 to come into it? again just a thought and welcome to the forum!
