He guys if u dono him, he has one of the best lowtech skimmerless systems and that too sps dominated.. https://reefbuilders.com/2011/01/04/sreef-stunning-skimmerless-reef-tank-marko-haga/ Soon ill be plannin on a 150g sumpless skimmerless system working on a eheim canister 2062 (the monster l) or a fluval fx6. Plannin on 100 to150kg of live or dead rock and 1" redsea ocean white sand (i dono howmany kg shud i buy). I dont like dsb some how. I want to solely depend upon liverock for biological filteration and nothing else. So the canister will have jus foam pads and polishin pads with phosguard, carbon and 2 bags of purigen. Ill also add a bag of ceramic rings or eheim media not as biological filteration but jus incase if i wana setup a new tank, the mesia will help cycle the aquarium faster. Now if u see Marco haga's system, he is using biopellets without the skimmer. Is that possible? Is any1 currently using then without skimmer? If yes, how? Can i add it right in between the filter sponges in the canister? So the bacteria stays in the sponge and doesnt come out. Might sound stupid, but jus a thot. Also is it really necessary to use biopellets? Well mostly im plannin to keep jus softies and lps, but i wana try sps too if possible. Any1 tried or using same method?
