Hello all was not sure if this should go in the sps discussion or not but here we are. How does everyone dose is it bad to just dose as needed or is it necessary to add stuff to your top up. My tank is 6 months old and up till now it seem water changes were enough. I do weekly water changes and test weekly but saw a decline after double checking the test so i added some trace elements. Is it bad to add as needed do i need to add something to the ato reservoir to increase it. I will try to attach the weekly number and a photo of the tank. It currently doesn’t have any acros thats why i didnt know if it could go in the sps discussion but it has 3 montis 1 encrusting 2 branching 1 stylo frag and another bigger stylo frag along with 2 torches, lobo and few more lps with 2 nems a bta and a rfn. So i dont want swings to affect them ideally.
