any ideas about my tank?

Post by lesleyanndunn »

since my fahaka died, i wanted to make sure my tank was fully cycled and safe before adding another one
i replaced the heater with a new one, couldnt regulate the temp properly for a couple of days, and the temp soared to above 30 and looked like cooked most of my ramshorns :?
my pond snails had went up out of the water and were above the water line and so they survived.
one of my shrimp also survived 2 days in cold water when no heater was on, and the 2-3 days when new heater put the temp up.

the temp has now stabilised at 25, and has been this way for 4 days. :)
i removed the dead snails, and did a wc and params were amm 0 nitrite 0 nitrate 5 :D

so i went and bought 5 guppies yesterday to keep the tank cycled until i got a fahaka in the near future
this morning, 2 guppies dead. no marks on then? :(
my params are the same 0,0,5, ph 7.6 using api test kit
is there something else in my tank thats causing the deaths? the shrimp is fine. been in there about 2 weeks, the pond snails are in the snail breeding tank now, and are in that water looking better.

other 3 guppies seem ok, only time will tell?
my tank doesnt smell weird or anything, the water is clear etc
only thing i can think of, is that something is leeching out of the rocks i got from the beach? same rocks are in my bw tank, and fish are all great.

I don't suppose you can borrow a hydrometer? That would check the SG level is there were any salts that dissolved into the water from the rocks.

Also closely inspect the rocks for little brown patched that look like rust. Some rocks contain variations of iron that are not good for the tank.
if you follow me, you avoid stepping in the crap that I just did...

Why would there be salt from a fakaka tank? Unless your new purchase is going to be a tiny one, I don't believe the guppies will put out enough bioload to support a fahaka. I'd remove everything live & either add ammonia (as per the fishless cycling article) or a piece of shrimp in a stocking.

Just a thought, but if the rocks were from the beach wouldn't they retain some salts?

I'm not saying it is indeed the rocks but there are a couple things in the rocks to be careful of.

In the below 2 pics you see 2 rocks. The one on the left is tank safe, the one on the right is not. The one on the right contains traces of iron in the glittery "pyrite"

"Unfortunately, pyrite does not seem to be very good for the fish tank. This article at cichlid-forum.com states that it's reactive enough to acidify water, and potentially release more iron than is good for one's tank, which is bad for fish and terrible for inverts, and I'm finding enough consensus searching on "pyrite aquarium" to back it up. (The problem being that the "sulfide" turns to "oxide" over time, releasing sulfur, which reacts in water into sulfuric acid, and then you've got iron oxides, which can release their iron, especially in low-pH water, and ugh."
