First time post so I'll give a little backround on what i know and my setup as I've read enuf of these to know that's very important information. I'll be brief.
Started into the hobby with my 6yr old daughter about 6 months ago. Both her and I have become pretty much addicted to it at this point and enjoy even the PWC
I have a 75g aqueon rr tank w/built in overflow. 75lbs of live rock and 150lbs of sand/crushed coral substrate. below that I have an e-shopps R-200 refugium sump (I think it's a 30g sump) with about a 3" sandbed and a couple big chunks of cheato. I have a reef octopus (nwb-150) sitting in the first chamber of the fuge as well.
water flow: running 2 maxi-jet 900's and 2 koralia nano's along with the flow from the fuge return pump. return pump is 630gph. That being said...I think I'm good for flow, but if i'm not...please tell me.
Live stock: I have 1 hippo tang, 1 percual clown and 1 firefish. 1 torch coral (about 5" diameter), 1-Alveopora coral (4"), 1 piece of star polyps and some zoas.
Lighing: 2- 250w hqi halides, 2-54w actinic, 3-night leds. total cycle (before algae outbreak) 8hrs. total cycle (now) 4-5hrs. i turn on the actinics about 30 min b4 the halides go on.
Finally to the question.....Tank was running nice and smooth.
sal 1.023-1.025 (have refractometer) learned my lesson with those piece of junk hydrometers..almost killed my fish when sal went up to 1.031 using that hrydo!
I'm having a slimy algae outbreak. Algae is browish, stringy and slimy. sticks to GHA and mostly substrate, but i do see it on the catch on the glass, but not nearly as much as the substrate. I THINK it was from excess nutrients in the water b/c someone told me to feed the torch twice a week with this zoo plankton. I was feeding like 5ml of that stuff trying to taget feed but a s*itload of it was im sure flowing right passed! I was now told by someone else that that's ridiculous and un-necessary. I should feed the coral once a week...maybe. What's right.....I don't know, which is why I'm coming to all of you!
either way...i started getting this slimy stringy algae outbreak and noticed my cheato is shrinking! my nitrates are at 0, which they've never been before. Im reading that the algae is consuming all the trates and leaving nothing for the cheato to feed on and that I need to shut the light off to break the cycle. I've been doing pwc
every other day (only about 5-10g) which someone suggested and dropping lights down to 4-5hrs per day to try and stop this horrible crap from growing. Seems i have slowed it down, but it's not gone.
I'm worried if i leave my lights off completely, that I'll hurt my torch and alveapora coral and I love those things and would really hate myself if i killed em! Will they be able to withstand a couple days in darkness in order to kill this slimy algae?!?!
Other then the algae problem....everything seems to be nice and healthy. Tang has really gown from when i got her. she feasts on the little algae sheets i give and the clownfish and firefish are fierce eaters as well. I feed frozen mysis shrimp (yes, i soak it and then run RO
water over it thru a filter about 5 times before dumping it in tank)
I'm getting to my wits end with this effin algae....help!
