Hello everyone. I really need some advice for my new set up tank 2 weeks ago. For the substrates, I used Fluval Stratum substrate but I was curious and did a stupid thing. I add some of fertilizer under the substrate https://www.amazon.com/gp/product/B01MF77OID/
. My logic was that fertilizer was advertised as organic, so it wouldn't hurt if I have some under the substrate? Plants in my tank: Ludwigia repen, ludwigia mini, pearl grass, dwarf hair grass, coontail, guppy grass and elodea anacharis.
And now I'm facing a real trouble, as the title, the water is smelly, not that I can smell from across the room but still notice if I come close to the tank. Water is also turning cloudy and I notice biofilm everywhere, on the surface of water, glass and any objects in the tank.
The weird thing is my ludwigia repen and ludwigia mini are still growing new leaves. My pearl grass stems now look longer than before. Guppy grass and elodea grow new roots. I'm not sure about dwarf hairgrass since I'm scared to disturb the substrate to check now. https://imgur.com/FUERAAN https://imgur.com/3MlSWOI https://imgur.com/MMKlLps https://imgur.com/yI4ZzBw https://imgur.com/nNRXI83
I tested the water with teststrips:
PH: 6.8 https://imgur.com/8sQTYHW
My other fish tanks with 1+ year old show the same GH so I thought GH alone wouldn't be a problem.
I really don't know what I should do to treat this tank, or just rebuild it from scratch. The plants may look not dying but I have a feeling if I don't do something, it will affect my plants soon.
I also have a question, my albino cories just laid some eggs this morning. I have no experience how to raise cory fries, should I just leave the eggs there? The cory tank also has some kuhli loaches, ghost shrimps and snails.https://imgur.com/UePTDT6
Thank you in advance for your time
