Hi all, I have just checked the tds on my RO water from the lfs and it is reading 265ppm!! I have had the water for a while, does it deteriorate with time? Also I am testing it cold because I haven't yet started to heat it, does that affect the reading? I do get quite a lot of green hair algae...

Hi there I don't have any up to date readings for my marine biorb but it is a 60litre tank which I have had running for about 2 years now - the ammonia, nitrite and nitrates should all be 0 but I think my test kits are not accurate so when I go to collect my RO water, the lfs tests my water so...

Hi all, I have had a most frustrating with a lfs regarding their RO water and readymix saltwater, so I just wondered if somebody could verify how important it is to measure the TDS? The first shop I went to for readmixed saltwater gave me water of too low a salinity and when questioned, blamed...

Hi all. I've just purchased a purple firefish for my tank and I am finding it very strange to see him just staring at me all the time! Literally, like alway's just hovering and looking at me whenever I am in the room. I go out and he darts in under the rock!! Sooo funny :laugh:. Anyone else...

Hi, I was just wondering if anybody could tell me what is happening to my giant feather duster worm please. I checked the other posts but couldn't find the exact problem I have so I thought it best to start a new thread. So...the tank has been running since beginning April, 60litres, stable...

Hi all. I have just bought a pack of chaetomorpha and halimeda to try my sea slug on and I was wondering if somebody could give me some advice on putting it in my tank. It is a 60 litre biorb with no sump/refugium, so it will be going in the tank. Can I anchor it to a rock and if so what is...

I have recently set up a marine biorb (don't all complain, please!) which is going very well. All params have been 0 since setup and I now have 3 hermits, 2 turbo snails, 1 clown goby and a newly introduced cleaner shrimp and lettuce sea slug. My question is, why does my sea slug seem to slow...

Hi - I was just wondering if anybody could tell me what might have got into my tank! It is tiny (3/4cm) and sort of star shaped, with one of the points being slightly larger than the rest. The points are quite blunt and rounded, it is more flower shaped really but it moves quite fast! :D It is...

Hi, just introducing myself as a marine newbie. I have had a marine biorb going for 3 weeks now with no problems - it has 3.5kg good quality live rock and two turbo snails (Spathiphyllum sp.). Before anyone starts to complain about my choice of tank could I just say that there any plenty of...
