Good plan, already well underway.  Seems like you're doing just fine.

Thanks:

Cheers :) I might just add a timer to the plug for now,

Also, I’m feeding the clowns and my shrimp once daily, on frozen brine shrimp. Will that be enough? They generally seem happy but all three go nuts when I put food in, and snaffle it all up.

Nice additions, are you monitoring the phosphates?  As for feeding, just make sure the amount you put in is all eaten up by livestock otherwise it'll just go against you.  Eventually ;)

Good morning all, and thanks for the comments.

I'm not currently testing for phosphates, but I am starting to think maybe I should. The issue is, I seem to be getting mainly the 'brown algae' diatoms, which is why I was leaning towards my lights being on too much through the day, but having said that; would the over use of lighting just turn the brown to green anyway?

previously, I left my lights off for two days, but now there's coral and fish in there I can't really do that  :grin:

shortly before my last water change, I brushed the brown from the top of the rock then used a syphon tube to remove most of the stuff on the sand. The CUC seem to disperse of it quite quickly, but it soon comes back. I don't want to add more CUC as there's already 7x snails, and it's only a 56L tank.

From empty to full

Looking at the cloudy water from the pictures when you first put the water in, can I ask did you pre rinse the sand before putting it in the tank?

I'd suggest you need to consider is the detritus now settling atop the sand?  If so, I certainly wouldn't let that settle as it will only build up and eventually go anaerobic which is when problems will arise later on; for example untouched sand can cause an ammonia spike if stirred up after a long time stationary.

If it was me, i certainly wouldn't let it settle. 

I recently took my sand out of my tank to clean, kept in a dark box.  Whilst my tank has been bare, it's surprising how much detritus builds up daily.

Do you turkey baster your rocks just before water change?

I didn't pre rinse as it was 'live' sand, and I thought that if I rinsed it all through I'd just be getting rid of everything I wanted in there. When I do my water change, there's rarely much on the rock, but if there is, I usually give it a gentle rub with a very soft tooth brush attached to my syphon tube. So when the 'bits' are disturbed they're sucked out of the tank and into my bucket.

I've been keeping a close eye on what food is left in the tank after feeding and so far I can't see that there is any. It seems like the fish take most of it as it falls/circulates and what ever falls down to the sand is gobbled up (almost instantly) by the shrimp. Over the past week, I've had to remove 1 tiny bit of brine shrimp. In all fairness, I'm not feeding much. I've had the food for about two weeks and only used just over one cube.

+1 on the conch. Mine is doing great work on the sandbed.

Other thing to consider is your flow. Make sure your power head helps water back to the filtration.

In regards to flow, the Evo Sea has two outputs (top left of the back tank wall) which can be independently positioned to generate the required flow. I have one pointing to the left of the rock and the other to the right, both pointing to varying degrees of 'down'. If I put something in the tank which will float, there appears (somehow) to be a circular motion around the rock, and the fish appear to be swimming against a current. I do however have a Fluval CP1 which is not currently installed. I bought it whilst it was on sale in case I decided to get more corals in the future which required more flow around the tank.

as for the conch, would I have enough space (and food) for one? I only have 52L and already have 7x snails and a fire shrimp.

Your snails are astrea and trochus by the look of it. They will eat algae off the glass and rock (mine are a pain and only like the glass!) they won’t like feeding on the sandbed. Nassarius and conch are the best at digging around in the sand to keep it turned over.

Perhaps a couple of nassarius snails would be better suited to your tank size.. You can always suplimenty feed them if they have done too good a job of the sand bed and gets hungry. I have one or two in my tank and early on before the tank was established I would put a couple of small pellets on the sandbed in front of their antennae and they would emerge to eat them.

I only mention flow because I had issues were I had undetectable nitrates and phosphates but kept getting cyno and hair algae. It was happening because too much detritus was settling and creating localised pockets of high nutrients because it wasn’t getting suspended in the water long enough to get filtered.

It may just be diatoms from silica leeching out of sand. It happens a lot in new tanks and it will pass without you needing to do anything if this is the case.

I was hoping that it was diatoms from silica, but I'm becoming more and more confident that it's lighting issues.

For the past two days the Mrs has turned the lights on when she leaves the house, and I turn them off in the afternoon/evening, so the 'light on time' has dropped from 12 hours to 8.

I've already seen a noticeable drop of 'algae' on the sand bed, so I'm hoping that if I keep up with the reduced light and removing any little bits I can when doing water changes, it will be resolved with time.

on a side note, it also looks like the Corals may be doing better with reduced light, but that's something I will monitor for a bit longer before getting too hopeful  lol

once again... thanks everyone for the help and advice  :grin:

Good stuff,  btw if it is diatoms then you definitely do have silica in your water. If you're making your own water, it might be worth double checking the DI stage is working properly 😉

I don't currently make my own water. Initially I was going to set up in my garage to produce and store my own water, but considering I only have 56L, it really wasn't worth the hassle for 10% water change once a week. My LFS is approx. 3 miles from my house and charges me £1.50 for 25L of water to do my change.

The first and third time I bought from them, they tested the water whilst I was there to demonstrate it was decent. I was happy with the result, and have had good word from others who use the same shop. I suppose I could test the next batch at home to see how it goes, but I'm fairly confident the majority of my problems are lighting related, as when I left them off for a few days it cleared away quickly and since reducing my 'lights on' time it has significantly reduced  8D

I suppose, as long as my fish are healthy and it seems to be dying down I don't mind it being a bit dirty for now whilst I try and balance it all out.

Don't worry mate, just a bit of pedantry on my part.   :P

All I was getting at was that light or silicate alone doesn't cause diatoms to grow,   they grow when their needs are met, and that's light AND silicate AND phosphate AND nitrate.

If you can limit any of those things below the levels diatoms need, then you can eradicate them.  Sounds like you've already done this by reducing the light.  8D


On the subject of silica though, it doesn't show on a TDS meter, so that's how the shop can show you a zero reading but still have it in the water.  Really not a major issue though, so don't worry about it.
