I added 1 bushy nose, and 2 flying fox last night. Within 10mins the bushy nose was on his back at the bottom and the flying fox were at the top gasping. All of my other 10 or so fish were fine! I tested the water to discover

2+ phos
normal nitrate
16 kH
25gH
Ph on the probe was reading 7, but I recalibrated to find it drifted and was actually at 6.

This gave me an aprox ppm of co2 @ 250ppm Extreamly high. A 60% water change saved my new fish, but I am wondering why the old fish were not affected?

Also I had a huge BBA "bloom" in the last 2 days, I'm sure its due to the 2+ phos. but I always hear that you need to increase co2 to help, but with the co2 at 250ppm how could the bba have gotten so bad.

I had done my last water change right about a week ago, so I dont understand how things could have gotten so bad so quick.

Please help me figure out whats going on.

Are you sure about the pH and KH readings?

Your water sounds like liquid rock.

I show 480 ppm of CO2 with a KH of 16 and a pH of 6.0.

And what are "normal" nitrates?

2 ppm of phosphate in a balanced planted tank will not cause a "huge bba bloom".

yeah i understand that... but how did it all goto hell so quick.

Tank lvls measured last night.
Phos-2+ ppm
nitrate 20ppm
Kh15 dergees
gh24 degrees
ph was around 6.2

my tap water.
phos-0ppm
nitrate-2.5ppm
kh-5 degrees
gh 9 degrees

I just got home today, and my water is real cloudy.

what color is your cloudiness? white or green?? also u didnt say what your ammonia tested at .. sounds like over loaded biofilter.. try & test ammonia & if high do small wc & get some bio-spira to help reseed your benafical bacteria:icon_idea

its hard to tell. prob like a white. looks like a bad 80's porno, haha its hazy.
i just did a 60% water change last night. I dont have an ammonia test. overloaded biofilter? with the co2?

just thought about it. Are you saying that the co2 spike killed the biofilter, which in turned made everything go nuts?

some times to big of a WC to often or not enough, can really screw up ur biological equlibrium. been there done that!! especally when fish are concerned always test ammonia frequently ,whats your water temp? also those gh & kh are really high u should try & add some distiled or ro/di water to soften it up distilled waater is completly void of anything so 50% cut with tap water should do nice did u have an end of tank {co2} dump or what? sometimes adding 1 fish can overload maxxed out biofilter with low o2 levels also white haze means high ammonia= bacterial bloom they need ample amout of o2 to survive

If your tap water has a KH of 5° how come your tank is at 15°?

ok todays levels are.
nitrate 0
phos .2
gh 15degrees
kh 11 degrees
ph 7

all that i have added since WC yesterday is a double dose of excel.

Do you have a lot of evaporation in the tank? If so do you top off with tap water?

What's the substrate? Any rocks in the tank?

hmm its been in for a while with no effect. I'm gonna do more reasearch to verify if this the problem. This stuff doesn't look like the pics that come up when I search it. And its extremely hard, hard rocks usally dont disolve much, right?

Trust us. Look at the water chemistry. Something is making the tank water harder. It's not the Flourite. And unless you have Aquarium Faeries coming by at night and doing something to harden the water then it's the rocks.

Dolomite = limestone.

I don't understand how you think it has had no effect. Hard rocks dissolve. Face it, something is messing with the water chemistry.

If you don't believe us then take a piece of that rock, if you have some that's dry then use it otherwise remove some from the aquarium and let it dry throughly, now once you have this piece of dry rock drip some acid on it. Vinegar may work. I prefer muriatic acid. Notice that reaction? That's because it's a carbonate containing rock. And it is affecting your water chemistry.

the rock might have been fine for a while but when natural acids in the tank build up (CO2, humic etc..), it starts to dissolve the rock. Water doesn't dissolve rocks. It's the acids.

co2 can start the reaction? the co2 is new. I would take it out in an instant, but there is around 200lbs of it in the tank, and I'm not 100% sure it is dolomite, so I'll test it first.


Rex- water won't get hard typically? If its 5 from the tap, it will stay 5 in the tank unless you have a rock or something disolving?



you can't even see 1/2 of it. If in fact it is the problem, I've got to tear down my tank.

If your tap water is 5 it will stay at five or slowly decrease. If there is something leaching into the water it will get harder.

And you don't need CO2 to have it happen. Water is the universal solvent.
