Hello last week I joined the forum and I have been keeping a 10 gallon for about 4 months with no problems till last week I took some pics and posted them here, my tank was lookin great (so I think) but the very next day I woke up to find red cyano on the sand bed, battle it for a few days but it kept getting biger and bigger and I decided siphoned it out. after that my BTA STARTED to show his mouth open so I quickly check the water to find very high NITRATES and proceeded to changed 50% of the water Sunday a week and half ago then it went down to about 20 and I thought it was gonna b fine so I let it sit. On wensday check water again to find NITRATES at 40 so I proceeded to change 20% of the water and let it Si till this pass Sunday check the water again and it was at 20 so I didn't change the water but I checked it yesterday and they were back at 40 so I change 10% again . I have a black and white stripe damsel 2 oscelaris 7 hermits 1 peppermint a Mexican turbo and 4 nassarius there is also a turbain but i think the nitrates r stressing it out and probably is not going to make it but all the rest o the inhabitants r doing ok considering(except BTA and snail).
I don't wanna change too much water to quick coz I don't want the tank to go into cycle again, that said how much more can I do water changes w/o risking the tank ???
