[SIZE=10.5pt]Hi all,[/SIZE]
[SIZE=10.5pt]I have had my tank setup for 3 months now and it has been fully cycled for about 6 weeks (I did a fish-in cycle as I hadn’t done my research and listened to my LFS), details of my tank/stock below:[/SIZE]
[SIZE=10.5pt]Juwel Rekord 800 110L Tank
Juwel Filter Bioflow Super
Juwel 100 Watt Heater
Tetra APS 100 Pump with 4" Air Stone
4 x Glowlight Tetras
4 x Neon Tetras
2 x Flame Red Dwarf Gouramis
1 x Lyretail Sailfin Molly
7 x Molly Fry (I will be trading these with my LFS when fully matured - they were born in my tank and i don't want it overrun with Mollies)
2 x Tiger Shrimp[/SIZE]
[SIZE=10.5pt]I am unsure as to which filter sponge does what, i have been following the instructions that came with my Juwel Bioflow Super and it advises to replace them as follows:[/SIZE]
[SIZE=10.5pt]I replaced the black carbon sponge 3 weeks ago as my LFS advised that this doesn't need replacing, but just needs a good rinse in removed tank water monthly (I was advised to wait until my tank was definitely cycled before cleaning this which is why I didn’t change it after my first month).[/SIZE]
[SIZE=10.5pt]I test my water every 2-3 days as I am a bit cautious about causing harm/killing my stock, and all the levels were fine up until 2 weeks ago (Ammonia was still being converted for a week after changing my carbon sponge), my Ammonia then started rising fairly quickly, one day it was 0, then 2 days later it was up to 0.4, I have been having to do 2 water changes a week, my usual weekly 25% when I do my gravel/glass clean and an extra 50% in the middle of the week to battle the rising Ammonia.[/SIZE]
[SIZE=10.5pt]I am no longer seeing any Nitrite as the Ammonia does not seem to be getting converted, has anyone seen this before or have any ideas as to what I can do to fix this?[/SIZE]
[SIZE=10.5pt]My LFS advised me to take a couple of bags of water from them and add this to my tank to help rebuild the good bacteria, which I can’t really see a problem with as all their fish look really healthy and their tanks are nice and clean, but it does not provide an answer as to why this has happened and how I can stop this from happening in future.[/SIZE]
[SIZE=10.5pt]Does anyone have any ideas or seen/been through something like this themselves before?[/SIZE]
[SIZE=10.5pt]Just in case anyone asks, my levels are currently:[/SIZE]
[SIZE=10.5pt]pH[/SIZE][SIZE=10.5pt] 7.6 [/SIZE]
[SIZE=10.5pt]NH3[/SIZE][SIZE=10.5pt] (Ammonia) 0.25ppm
NO2 (Nitrite) 0ppm
NO3[/SIZE] (Nitrate) 100ppm – Jersey tap water is higher than this at present so my tank is removing some of the Nitrates
[SIZE=10.5pt]Any help will be greatly appreciated as always![/SIZE]
[SIZE=10.5pt]Thanks[/SIZE]
