So I’m about to do my first tank transfer I have the innovative marine 15 gallon but moving everything to a IM 20 gallon I know not a huge jump lol. I just had a few questions I plan on adding more dry rock to the main display tank besides the rock in my current tank and the seachem matrix in the sump if I add new dry rock will it cause a mini cycle or anything bad? Plan on adding new sand I have too many spaghetti worms in my current sand and just want to start fresh so I can maintain them. Also have a question about the flow the IM 20 tank came with two 130gph pumps while I bought a mighty jet 326 for my 15 gallon I plan on putting the 326 in the 20 gallon but I also plan on buying another to replace the other 130 pump would two 326 pumps be enough flow for the tank alone because tbh I don’t want to buy a wavemaker
