Oh I worked out what they are! I think they're baby astrea snails. I have three that I added to the tank, they must've bred. I didn't realize that could happen so easily. Saw a bigger baby and it looks much more like an astrea, the mouth and antennae and shell all look similar

^True. I might reduce my lighting to 6hrs from 8, or alternatively I'll make it spitball overlaps with the ambient lighting so no extra light. Guess I'll have to wait for the nutrients in the rock to burn out if I keep siphoning and water changing regularly. Once my phosphate test kit arrives...

Would it helped if I turned lights on early to overlap with the ambient light? I was holding off on this cause then I can't see my tank at night when I'm home. But I guess that's ok for now whil I'm dealing with cyano.

Can anyone identify this snail I found in my tank? About 3mm long, has a white shell with a little black spot I'm assuming where the spiral is developing

Oh also I pruned back my macroalgae by about 80% a week beforehand my outbreak. It's all alive and healthy looking but its growing very slowly now (I think because nitrates are not 40ppm anymore, now they're 0-10). I'm wondering if this could be responsible for my cyano, the loss of competition...

Light cycle is 8hrs a day, the tank gets another additional 4-5 hrs of ambient light before the lights come on. Refugium on 18hrs a day, off when tank is on. Yes cyano in the fuge. Strange thing it's stopped growing on my macroalgae which is was before. But it's there. I just have standard...

Excellent! One clearly dominates the other now. One does this weird twitching thing too but after some research apparently that's normally submission behavior haha. Feeding once daily, sometimes miss a day once a week or twice, just to help battle cyano. But I don't feed much. Oh also they're...

Thanks guys for the discussion previously I found it very interesting! It's funny cause erythromycin was the final answer to my last exam question the other day!! Anyway the uglies phase continues. I'm siphoning off the cyano whenever I water change and it grows back mostly to the same amount...

If it helps, my aquaone slimmer kept overflowing for 1 week after it started.

Haha great discussion guys! I know about erythromycin, it's a macrolide antibiotic which inhibits a region of the ribosome in the cells and prevents protein production by the cell. I'm surprised that this doesn't affect other bacteria though...? We use it in hospital to cover all sorts of...

What are your opinions on a tank black out? I just have GSP and a leather so they'll be all good for a few days without light. Haha I left a small GSP frag on the tank "rim" where it was just staying moist within a water puddle by accident, I put in back in the tank after 10hrs and it opened...

Ok so... Cutting lights will help Nutrient control will help I thought it's weakly attaching an drew so high flow makes it difficult to establish on rocks and makes it float around in the water coloumn until it finds a lower flow area or is skimmed out?

Hahahaha 2 quills... Oh hmm...I have 2 powerheads on either side of the tank and they are located near the back of the tank. The cyano (majority) is growing in the front middle of the tank. But I don't know if that's a flow thing, a light thing, or something to do with that small piece of...

Oh yup I think it is cyano, it looks exactly like the pictures and the patches which have been growing for a while have stringy red algae coming off them which can be blown off with a wave of the hand

So 2quills, I have both Chaeto and caulerpa serrulata in my fuge. What lighting period would you run? I'm currently running 19/5. What would you suggest? Regarding the comments about the rest period, I was taught that plants require a dark phase to stimulate respiration and growth because...

Thanks for the tips with both the food and the chemiclear, I see it says a bacteriacidal so I guess that would do the job quite well. I'll give it a few months first. Haha my family looked at my tank and said "Wow that's so cool! Look at all the purple and red and green patches on the sand and...

Yup my initial research suggested the same thing. So I feed mysis 4 days a week, pellets 2x to get in any nutrients the mysis doesn't have, and then one day no feeding. Good idea though maybe I'll reduce to once a week pellets instead

I see so if this ugly stage and the cyano doesn't resolve after a few months I'll consider upgrading my flow.

Oh yeah I always thought what matters is the velocity of the water blasting different areas of the tank. So it's about 105gallons x21.5 = roughly 2250 gallons per hour

So I have 2500+2500+3600=8600 liters per hour. 400L tank, so 21.5x tank turonover spread over two powerheads and my return pump. That ok? I think my LFS said 15x would be fine for a softie tank.
