Need advice from bros... button polyps is best placed on sand or rocks? Having 34l tank buttons not fully opened so do I change water daily bit by bit until it opens? And dose good bacteria booster at the same? I often wonder how u guys managed to get softies open up big abd nice. I know water condition is key and despite having skimmer, wm, poly filter, I still have problem with mushrooms and buttons not opening. GSP is doing well. Thanks in advance for your advice.
