I thought green bubble algae (valonia) came in several shapes, including sausage shapes. I'm told Emerald crabs eat them, although I can't get them in New Zealand so I don't know. Desjardini Tangs are also supposed to eat valonia. I increased my Magnesium gradually to about 1350, kept my kH up...

I had the worst plague of Green bubble Algae (Valonia) on the planet! There were BILLIONS everywhere and I use to laugh when people told me to pick them out! In New Zealand we cant get emerald crabs, so this is what I did. I added phosguard in to my sump in case that was the issue. I raised my...

Ive noticed in the last week or so my Kenya tree is "saggy". Theres a couple of branches that look O.K., but the rest is withered up looking. Any ideas as to why?Do they have a life span and then die or what?

Hiya I get it to go to blue from purple with as little as one extra drop of solution C but I don't use the needle on the end as it takes too long to get enough solution C in to change it, and it changes fast. When it does go blue, read the amount that's left in the syringe as per instructions...

Valonia Problem I have a severe problem with an infestation of Valonia in my Reef Tank. Brief summary of tank: Approx 735 litres (200 gallons) tank with refrugium. Temp about 25 – 26 degrees C (78 F). Has a U.V. filter, protein skimmer, chiller, 2 heaters. Phosguard in the...

Actual Yes. My new Lieutenant tang had developed brown speckled patches over his body. He was obviously itchy and he was scratching and flicking in the sand. I caught him and put him in a quarantine tank for 3 weeks dosing with copper. It went away and I returned him to the main tank and he's...

I had a similar algae problem with slimy brown stringy algae. I turned my lights off for 48hrs (didn't hurt the corals) and installed a U.V. light filter. It went and hasn't come back.

woops, wrong thread

I haven't got any answers for you, just questions to those who have answered! If you take all the fish out, treat them for a number of weeks in a Q tank and then put them back into the main tank which hasn't been treated because of the corals, won't they just get it again because the ick is...

Crikey that's a mystery. Phosphates and nitrates all zero I have 3 tangs and a foxface- wouldn't they pop them when eating them? There's zillions so it's impossibe to scrape them out. I tried to on one rock which I removed from the tank and rinsed after scraping, they just grew back. Boo hoo!

I have Green Glassy bubble Algae throughout my tank. Is there any way to control this?

Hi I have a 200 gallon tank with lots of different fish, including 1 Bangai Cardinal. Can I get more of these? It says on some websites that cardinals can be aggessive towards their own species.

You don't know how computer illterate I am! If I can work out how to....!

Fighting tangs 3 weeks (or so) ago I did what the books say not to do and got a yellow tang about 2 weeks after getting a purple tang. The purple immediately started beating up the yellow. About a week and a half ago I caught the purple tang and he's living in the sump (I've put some rock etc...

A couple of weeks ago I wrote about a plague of stringy brown slimy algae throughout my tank. I got lots of different suggestions. (My water chemistry was great with zero nasties). After turning the lights off for 48 hrs and adding a UV light filter, my brown algae problem has gone and it's been...

My new Lieutenant tang has developed brown speckled patches over his body. After about 2 days I finally managed to catch him and he is now in a quarantine tank dosed with copper. That was about 2 days ago and it seems to have spread more across his body, but he is eating. Should I be doing...

Hi reefsahoy, Now thats interesting! Yes they were dead rocks! you're the first person that's suggested that as my problem. I've got 2 bags of Phosguard in the sump too. I turned the lights off for 2 days and the brown algae has gone and green is now growing back. I've cut my lights down to 7...

I am using R.O. water, it's quite a big unit. But I've never heard of a DI chamber. Can you describe? Thanks a lot.

Thanks ltljoker. Yeah it's my purple that is mean and he's smaller than the placid yellow!?. I have had my lights off for 2 days to help deal with an algae problem so that should help with this too. I'm going to keep the division in for 2 weeks and then maybe cut bigger holes in the divider for...
