so my 20g long has a .5g hob fuge with cheato and maybe .5 gal hob filter that’s holding biomedia. I started the tank almost a month ago. Added in a larger bottle of dr Tim’s one and only and a bottle of biospira. Ended up with spiking nitrates last week. Wondered if it had been too much bacteria added and a die off of it caused it to spike 50+ (Anyone know if that much bacteria can cause a die off that would affect your nitrate like that?) Did a 20g+ wc over the last week and I’m down to 2ppm nitrate today’s test. But I have this maybe 3 ish day old occurrence that I believe I saw last week. This algae on the glass (barebottom too) and bit on the rock. Is this just part of the cycling? Should I scrape it off the glass? Leave it? I already have a cuc in so should be ok there. Might get some more snails.
