All aquatic life are healthy & thriving.
3 Albino Plecos, 3 ghost shrimps (Riceland Prawn) & 10+ mosquito fish.
Little bit of green algae on the driftwood & green spot algae on the glass which indicate phosphorus deficiency if I'm not mistaken.
Driftwood position changed during yesterday cleaning & water change.
Around a week ago one & only one Albino Pleco went missing. Nothing left from it to indicate it died. Maybe my cat ate it, I don't know.
There's a lot of organic materials on the gravel that I have tried to remove many times.
Have BBA problem in the past. GHA recently until I trimmed all Bacopa & Ludwigia plants & then did water change. There is still green algae on the glass & on the gravel.
Unfortunately, during big water change yesterday, when I syphon 90% of the water & also removing a lot of organic mater, I think there's ammonia spike because the guppies & ghost shrimp looks agitated. I thought when I refilled with dechlorinated water, all will be well but no. All 4 guppies are dead in the morning & the ghost shrimp is dead this morning. As of now, it doesn't have any aquatic life in it.
I used to have a small filter in this tank with activated charcoal but it is old activated charcoal. I removed it a week ago. Maybe when I removed the filter, it change the balance in this tank. Should I put the filter back & with new activated charcoal?
Anacharis frequently in & out in this tank because of the GHA. Now I put them back in to help filtering the water.
I also have problem with water lettuce keep dying. They used to be OK before but not anymore since a couple of months. I keep taking several from Tank #1 & put it in this tank.
Bacopa caroliniana, Ludwigia sp dark orange & Cryptocoryne Wendtii are growing well but looks dirty. Java fern windelov looks OK but dirty as well. For eleocharis grass, I can see few strands survive.
The dechlorinated water that I use for both tanks is filtered water - mechanical filter & carbon block (around almost 2 years old I think).
