73gal DT running for 2+ years, stocked with mixed corals and 8 fishes, (cleanup crew: few crabs, tongo snails, just two really big nerite snail.)
since last two months i been dealing with cyano, the purple slime all over the rocks and on sand bed. vaccum up all i can on rocks and sand bed 3 times so far spending atleast 2-3 hrs each time, I was expecting it would get better over time but it does not seem to be, plus when i did the 4th time clean up yesterday i found the rocks are covered with dark green hairy algae, I really haven't noticed it until i started vacuuming the slime, it was around 2-3 weeks before i had through clean and at that time there was nothing like this. I gave a try using a tooth-brush to clean it off but it wouldn't go. The hairy alge is on the 50% of rocks. Wonder why and what should I be doing.
Things i have changed around 6 months past:
- 6-8 months ago added MiracleMud 2Lbs on sump. Before adding i cleaned out the sump for all debris
- I had two kessil a360we + one hydra 26hd in the middle all along, 3 weeks ago i removed both the kessil and replaced with hydra 26hd
- first year i had gfo on phoshpan reactor, then removed 2nd year because my NO3 and PO4 were zero all the time and sps were dying, after research learned that i need to have some NO3/PO4, now my sps are growing well and some are really growing.
- was dosing nitrate and phosphate for nearly 6 months, then stoped as nitrate and phosphate were increasing.
Parameters I test them almost everyweek :
Salt: 35ppt
NO3 - 5 to 10
PO4 - .10 to .15
Ca - 350
Mg - 1300 (My Redsea test always shows this)
KH - 8.0
Dosing:
BRS KH and Ca set by Neptune DOS
Once a week RedSea ABCD, alternate week Reef-Roids spot feed.
Feed: alternate with Flakes, brine, pellets
Anyone experienced can guess how i can bring cyano in to control or if any of the changes made within few months should be removed! and how about this green alge!
I am thinking of getting a log of snails to clean the alge, any recommenation! (i had like 20 different snails, overtime they die or the crabs kills them, i have i think two huge snails but its all the time only on the back glass, never seen them on rocks, they are the reason my corals get knocked down sometime)
Also add back the GFO reactor.
Look at this pic took yesterday of rightside of the rock to notice the hairy alge.
