    We have a 700 gal, coral tank. we have been getting very good growth on the hard corals & the soft corals
    the tank is over 18 months old and consistent in its parameters
    we are using polybio pads, chem pure carbon & Seachem Purigen as part of the chemical filtration
    we have dual skimmers, 40 watt UV light and a range of filtration pads up to as small as 25 micron
    we are using 9 ecotech Pro LED lights & feeding is kept to a minimum

    For some reason we have just gotten 3 small patches of Red Slime Algae
    I have treated the tank 3 times with Ultralife Red Slime remover. the RS will minimize & then come back in the exact same places
    but even though Ultralife says it is coral safe, I am seeing my Joshua tree react badly to it & some of my zoo's have closed up

    any suggestions??

    Siphon out as much red slime as possible and increase flow in the area.

    That is a set of tests to be proud of. What are you using for testing?

    If it's just a few small patches I would stop putting red slime remover in your tank. Siphon it out and change/increase flow in those areas. Since its not an outbreak of cyano I would think manual removal and time will take care of it in due time.

    ^^^+1,red slime remover products usually induce the breeding of bacteria that can work as a temp. fix but usually (as in your case ) the slime will return unless other measures are taken.They can also cause other problems such as low O2 and or a bacterial imbalance.

    I use a company in the USA called AWT every 6 weeks. the litmus paper test kits are unreliable. they are OK as a bench mark but when you see the difference in the readings between the 2, it really shows it up

    thanks every one for your input
    i just received 2 more Tunze 6095's & I'll focus these specifically at these areas to see if we get a difference

    I should have also mentioned that the water in the tank is moving
    I have 2 x Tunze large wave makers
    2 x Tunze 6155
    1 x 5hp digital pool pump running at a minimum of 30 gal/ min for the sump & filtration
    1 x 5hp digital pool pump for circulation requirements in a closed loop system. this is at 18 gal/ min
    both pool pumps are directed through a total of 10 jets we put in the system & the water exits through 6 skimmer/ strainers at the top

    but I am willing to try focusing a little more juice to those areas as the RS is growing on hard corals, so they would at least like the extra flow
