Hoping someone can advise!
I've been having a ongoing issue with diatom algae now. going on 3month plus. Its a cardinal shrimp tank with blue bolts, running for around 7-8 months now. I have around 40 blue bolts in there at the moment. Its a 30 litre tank and I use RO
water with Salty Shrimp KH
+ dosed to the right parameters. I have a lot of moss in there which seems to be growing but as soon as the BA comes back its stunting its growth.
I've tried doing small water changes, physically removing the BA (Brown Algae) but it keeps returning. I've been considering getting a UV
filter to help but I am not sure if it is worth it?
Because my blue bolts are quite sensitive I'm hesitant to add any chemical/treatments
Water parameters below
PH - 6.6
AM - 0
NI - 0
Am I missing something?
