thanks for your advice, I know I should do RO, but im kind of lazy about that mess, for now levels are fine. Maybe ill end up selling it. The home depot flourescent has not done anything regarding temp fluctuations, also the chaeto is groing well. At the beggining I added a whole bunch maybe it died off or something, but the clove polyps died 2 days after adding the bunch of chaeto so im making them guilty, I should just have added a little and wait for it to grow.
I dont have any filter sponge at the back I took them out since the beggining, I hate them. I only add a little charcoal once in a while. Maybe trying to make up for not having a skimmer, I also do water changes once a week.
