Once a week and rinse the filter in fish tank water you siphon out.
Ok thanks, so will do the water change and clean the filter the same time every week. My concern was cleaning the sponges etc too frequently will kill the bacteria as well.

Hi guys
I am struggling with green hair algea.
Current set up is a 120litre tank, external Eheim 205 filter with added purigen, lights on 5pm till 9:30pm (no live plants). Stocking is BN plec, 2 mickey mouse platies, 1 platy, 2 dwarf gourami and 2 honey gourami. Fake plants and real bog wood.
I tend to feed the tank flakes each day, a pleco tablet here and three and maybe twice a week some cucumber.
What could be causing my issue?
Velvet? I think if you're going with tangs then a QT process is a must. Even if you aren't then it's risky, any issues are a nightmare to sort out. I made the mistake of going observational only a couple of times and got hit with flukes + internal parasites. Never again!
Sorry to hear about your tank. Your mistake was cleaning the filter with tap water. You should never do that and only change the sponges if they are literally falling apart.
You also shouldn’t change more than a third of the media at any one time if you need to replace it (the less you do the safer it is). Im still using the same sponges 6 years on.
The only things in the filter that you should change regularly is any carbon or fine floss pads but neither are necessary to even use.
Everyone that saw what was happening said something different, brook, velvet, white spot or fin rot. The anthias died in and under the rocks so I couldn't get them all out. So ammonia and nitrite was at deadly levels. Only the purple tang made it through.
Aac take precautions and treat their fish before sale, unfortunately the yellow and purple tang came from somewhere else.
I've since learnt that the real reef rock and quick cycling potions don't really go together. The rock doesn't seed very quickly, and then if any bad bacteria takes hold you're in trouble.
I'm working with the guys at aac to get the tank back on track. First with some polylab medic. And I've been running UV since the start of the year and getting good bacteria from any corals I add. Also added 12kg DD rock. 4 months later they felt confident of adding some hardy fish to test the waters. So I now have a 6 line wrasse and Midas blenny in with the purple tang. There's been no sign of any disease since December. The next fish in will be clownfish, which is the real test with regards to brook.
Do you have any photos of the sick fish from before they died? I'd be interested to try to ID whatever it was. A purple tang being the only survivor is really surprising as they're usually amongst the first to go.
I get all my fish from AAC, top shop in the country! They run copper at therapeutic concentrations which is pretty rare IME, and regularly flush through the system with fluke solve. But with the best will in the world it's impossible to treat all fish for all potential problems at that sort of volume. I can say I've never seen ich or velvet present there which are undoubtedly the most difficult common diseases to deal with. If you had velvet or ich then the only way to be sure your tank is rid of it before restocking is to wait 12 weeks (6 for velvet) with no fish in the tank. Medic is better than nothing but will only kill the free swimming parasite stage and dosing it correctly is virtually impossible as it's basically just H2O2 which breaks down very fast in a reef tank. Fingers crossed you won't have further problems.
I reckon you'd get away with real reef + bacteria in a bottle if you've got some other form of filtration like siporax in your sump. I have some real reef pieces in my tank and it's just not comparable to the real thing. I've heard good things about TCM eco rock.
11 anthias, that's a big bio-load increase considering how often they need feeding! Hopefully it was just ammonia issues rather than disease? I think I'd continue using medic for a lot longer (maybe 2-3x) the recommended time if I were you, and possibly at higher dosage. Especially if you don't have much in the way of sensitive corals and/or they seem ok. More chance of eradicating any newly hatched parasites that way. There is an interesting thread about using H2O2 on ultimate reef if you're interested as that's basically what medic is.
Anthias are lovely fish, can't wait to add more in the my new tank next year once that is all up and running, dreading moving all my stock over gonna be running two marines for a while until new tank can handle bioload.
Yeah great fish, the male Lyretail I lost was stunning.
Learnt some hard lessons in my first reef tank that's for sure, can't wait for new setup though, 3 times the water volume my dream setup
Its a constant learning experience.
I hope you're planning on getting some of the larger Tangs in this new beast.
oh yes plenty of tangs i hope, hopefully my one yellow tang is not to bothered when moved over to the new tank at the same time as the new ones don't squabble to much.
My purple tang was on its own for nearly 4 months. It was furious when I added the 6 line wrasse.
