Me also facing the same problem but I don't think they melting because of my BTA but i suspected the culprit is a crab in my tank because before they melt they look like being cut by something. But I did saw my shrooms that touch by my BTA and after that they start to bleach but still not melting.
I'm not using any calcium reactor. My tank is just a 7g nano tank. i don't know my tank kh because I don't have any kh test kit.
I will follow your advice. Thanx bro.
My Tank
2 True clown
1 Maroon clown
1 Saddleback clown
1 Green crommies
1.5kg LR
Wood airstone skimmer
Double Jebao fan
9W Boyu PL
Temp: 27-29.5
pH: 7.7
NH4: 0
NO2: 0
NH3 : 30
Maintenance: 10% water change every week and top up with alkaline water
I just check my water pH and the reading is 7.8. Before this I never bother to check it because I use alkaline water (pH 8.2) to top up my tank or make new salt water. Is this can cause my LR colour become brown?
Few days ago i put some sugar into my tank to get rid of algae problem. Yesteday i look at my skimmer and find that the wood airstone produce not so fine bubble and i tried to adjust it but does not make any change. How come? Should i replace it to a new one, i used it for only 3 weeks?
My temp. is around 28-30. I install a double Jebao fan to lower the temp and i only run the fan when i switch on the light. When i switch off the fan the tempt will rise to 30 so should i on the fan all the time?
When I add my maroon last week it looks agressive but after been attack by one of my common clown which is the biggest among them he been behave after that. I thought common clown suppost to be a peacefull fish but he is the one that try to bullies my other fish. Back to my question should i remove some of them?
