Well that was fast & simple Never thought about testing it first. Thank you.
I have something else to bring up. & the plastic igloo will continue below.. I have a 30 tall freshwater for 3 yr. having a few giant danios, barbs, tetras & a clawed frog. the frog has been in there for 3 yr. since it was tiny & has not eaten any of my fish. only the red roseys that I put in there for her to eat. it`s quite shocking actually on how she is with my fish, but that`s another story
Now a few mo. ago I was having a water issue with high pH. someone told me with having white gravel in there that it causes high pH. soooo I changed the gravel. I also was told to change the filter too, & by doing that it would lower the pH. & would be safer then putting pH down in it. well of course a cycling issue started.
after a couple months.everything got perfect except the ni-trAtes. no matter the % of water changes & vacuuming & making sure not to over feed that I done
they lowered down to 40ppm but only for a day & shot right back up to 80 & 160ppm. My trAtes was sky high for a long time. I used prime to make it safer for the fish. & had my stress coat & stress zyme.
I did not lose any fish in the time. I noticed 2 weeks ago I had black hair growing on a couple live plants that I have in there, so I plucked the leaves off. anyways I noticed a couple days ago my water smelled fishie. & yesterday I noticed one of my Giant danios had no interest in eating & was turning red from his tail fin up about a inch. I took him out & gave him a salt soak then I `d just go to the next step from there by searching online & seeing what it may be & what I might need to buy.
While he was soaking I rubbed him as he swam threw my fingers( not hard ) just enough to feel him. I put him back in the tank and noticed that the only parts that was red anymore was his bottom fin lining part on his body & the top fin linking on his back.
his tail body was very light compared to the rest of his normal body color.
he started swimming differently staying at the top or down at the bottom & soon after that the other danios was aggravating him so I took him out. I put him in another tank but he did not survive the night.
I have had the igoo in my tank for a long time for the frog. It came to mind that maybe it`s what is making the nitrAtes. Last night I done a very big water change.this morning I just tested the water & my pH is 7.6 I have 0.25 ppm
of ammonia 0ppm ni-trites & 0ppm of ni-trAtes. I have NEVER seen 0 nitrAtes with any of my water changes large or small.
the igloo is still in the tank. so maybe this last water change is what finally took the ni-trAtes out & I am back to a normal tank? & it was not the igloos fault.
what do you think was wrong with my fish? the others are all looking good
