how do i get rid of red algae in my marine tank?

Question

i got some red & blue hermit crabs it helped but its coming back my tank holds 190 litres

Answer 1

All tanks less then a year old commonly suffer from this problem. Increased filtration or a water skimmer helps. So will a wave-maker. You need to increase the water flow in your tank. I find that large snails do a better job then hermit crabs but your hermit crabs will slowly pick off your snails so that you will have to replace them occasionally. A turkey baster will remove the stuff from your rocks and a razor glass scraper from a paint department will clean your glass better without scratching it an delay the regrowth. I have a horseshoe crab that does a great job of stirring up the substrate and keeping it looking like new. Weekly water changes are essential and you must use reverse osmosis cleaned water

Answer 2

yeah, bottom feeders would help, try sea slugs or snails, but your crabs might eat them. You could partition them apart and alternate them regularly. You definately can fix it with snails. But u hav 2 keep the crabs away from them

Answer 3

Oh....the dreaded cyanobacteria......that red slime is yucky, isn't it? I had a reef tank for many years and every once in a while that stuff would bloom....its difficult to get rid of, not many sea animals will eat it....it usually happens due to a water change in your system.....anyway, read here, this will help you avoid and eliminate it......

Answer 4

well if you are afraid to use chlorine, you could always get a bottom feeding fish that will eat it all up in time

Answer 5

algae looks natural so leave it on unless its on your front/side glass then just scrape it off.

Answer 6

you need a good skimmer, and fed less to the fishes.
