Hey folks I have a 75 gallon display with 20 gallon sump, estimated total of 80 gallons of actual water volume. Heavily stocked with softies and lps. I have some carnation corals too. Under my stand I have the sump and a 10 gallon cube tank I WAS going to use for top off but I'm changing that up to adding a float valve to the sump for direct ro/di top off. My question is can I use the cube tank as a phyto growing/dosing tank? If so how would I set it up? Components and places to buy phyto and fertilizer to grow it would also be helpful. I've watched tons of YouTube videos but everything I've seen seems jank. Thanks for the help
