Interesting idea, good use of a siphon although it looks like it would be quite noisy in my living room...
Which salt brand are you using? Aim for KH 6.5 – 9 Ca 400 – 420 mg Mg 1250 – 1300 mg Your pH at these parameters should be around 8.1-8.3.
In general reef tanks are well buffered and if you get a protein skimmer, have your tank in a ventillated area and aim to keep your water parameters...
This is completely incorrect, CO2 causes your pH to go down from carbonic acid which promotes a reductive environment. This is a really good...
I agree damsels can be very aggressive and territorial and returning the fish to your lfs is IMO a good move. I would be concerned with your...
I had many of these flatworms for about a month and then their population crashed. Some more info on flatworms
Looks like a aceol flatworm probably Amphiscolops sp. They are harmless, if you are worried about them you could remove them manually by siphoning...
If it was my tank I would try to ensure the rock at the bottom of the tank is resting on the glass bottom not on the sand to avoid potential rock...
If you've already got a tang in there I wouldn't add any others. They tend to be very scrappy towards other tangs. The clown tang when adult needs...
Just have to be careful because tangs prefer quite a lot of swimming room, and in a 55g emporer angel or hippo tang get too large. you might get away...
I would do water changes with a quality salt mix using RO water as it is only 14g. I would say just do a couple of big water changes to sort it out;...
I had a blue tuxedo urchin, they prefer slightly higher salinity of 36ppt and a prefered temp of 28°C. They like to camoflage themselves with...
Manual removal and reducing phosphate and nitrates would be my suggestion, failing that a sea urchin will probably eat it although they can be very...
I've not heard of a bicolor blenny jumping out of a tank but they can be territorial and aggressive towards other blennies. I'm not sure if this is...
The best way to add carbon is in a reactor at a rate of 0.5g per litre/0.5g per 0.3 US gallon. If you don't want to buy a reactor or build a DIY one....
4 years ago I set up my first marine tank with live rock, snails, a sea urchin and a false gramma. After a month I saw sponges and hydroids appear...
