So I have a 135 gallon reef tank been going for about 1 year now with a trigger sapphire 26 sump that I had on my previous tank so decided to just use it until I had enough saved for a bigger sump. Was thinking of upgrading my sump now to something larger and maybe more "appropriately sized" for my tank. Just wondering if I'll really see any benefit from it as so far the tank is doing fine. In the sump I have a protein skimmer in the first section with the filter sock then a refugium in the middle which seems to be doing quite well so far. Just wondering if I'll encounter any problems in the future without going to a larger sump now. I should mention the sump does hold enough water if the power goes out so that's not an issue.
