Thanks for you reply OTPT and everyone’s elses help/advice
Well what I have done now is, I have removed the juwel background from the tank which has now removed maybe 99.8% of the BBA (let it try to grow now out of water..ha…ha
) and the rest can be spot treated with excel.
I loved the background and what it did to my tank looks wise. But it is just an algae magnet, and is either attracting algae with its make up or it just makes it real hard to kill it by not making it very cleanable.
I have read other forums where people are having the same problem with this background. And just thought to myself enough is enough.
With the back ground gone it has given me an extra 13% water in the tank and more swimming space for the fish, better flow and I think in the end it was going to be my only solution.
