So, I used to run Chemipurel Elite AND Grape Calurpa on a small 14 gallon biocube...very little algae issues, I did have brown algae (maybe diatoms) all over the sand for a while. I think in the end its a balancing act. Not only nutrient export methods but also clean up crew. Who do you anticipate ridding your tank of nuisance algae...
Side note: My newer system has very little chemical media in it (a small amount of Sea Gel in a mesh bag, sitting in 1st compartment of sump with skimmer. 2nd section has a small refugium with a 2-3 inch sand bed and a ton of Ulva and Chaeto. This seems to be reducing GHA in DT. Tank is 48 bowfront with barebottom (starboard) with 8 watt advantage UV. Running too short for me to say this is working but my nitrates are 5-10..and the algae in the refugium is definitely growing (I do like that it seems more natural than chem media) I've also carbon dosed to reduce N/P in a previous system but that ended up killing all of the macro but kept N/P great, but coral growth was terrible.
New method with little chem media and refugium is working for me now...
