Hi all, Looking for some help and advice with a stubborn diatom/algae problem.
I have a dark mat of 'stuff' that insists on growing over the piece of oak in my tank and occasionally forms in mats on the gravel substrate. Tank is 200 litres, moderate planting, light fishload, pH controller with CO2, CO2 is at or near 30ppm (tap water is pH6.9 and the controller aims for pH6.0), using EI ferts and weekly 50% water changes, lighting is programmable LED (low output, 8 hour photoperiod). Am=0 Nitrite=0 Nitrate =15ppm, Phosphates=5ppm, GH and KH I have measured but can't remember....D'oh!.....if memory is correct GH is 8 and KH is 2.
The 'stuff' can be peeled off the wood during cleaning, feels a little slimy, but seems to break down into a 'wet dust' when rubbed between the fingers.
I've scanned the web for pictures and descriptions of types of algae but can't see anything resembles the gunk in my tank. The nerite snails (four in the tank) seem to travel over and around it but can't keep on top of it (if they are in fact eating it).
Any insight into what this stuff is would be greatly appreciated.
I can't think of much to help you, but a couple of possibilities spring to mind. Do you have an external filter? The leak may be there and start/stop as muck inside moves and seals/opens a leak at the o ring or on one of the pipe connections. Or, it's possible that when the tank gets to a certain level due to evaporation that causes the flow from the filter outlet to change angle and overflow at the top of the tank - more likely if the outlet is facing a tank wall.
Just looking for some advice if possible. My son has a small 52litre tank with a few neons, a pleco and some scissortail rasboras.
Basically I think I have a leak, however I’m not sure if it’s just condensation dripping off the lid. The tank will be absolutely fine for a week or so, then suddenly lose a 2-4 litres of water overnight, then be fine again. Due to the amount of water loss I’m shying away from the condensation theory, although there is plenty of ventilation in the lid and it has lips on the inside of the lid before the outer lip, causing drips to fall into the tank not outside.
Does anyone know of a reason a tank may only leak every now and then? Because I’m completely stumped. I’m at the point that I’m thinking of stripping it all down and just re sealing the inside edges, but I’d rather not stress the fish if it’s avoidable.

In their defence, mine have "grown" on me and I now feel they're understated. Their tails are blood red, their fin colouring/patterning really stands out, and their eyes are good for making eye contact with (a feature I favour). The females in particular were very entertaining but that may have been unique to them, and it was particularly eventful when the males set off en masse in hot pursuit of a female, although I now just have males left. However, if they're not easily available, then perhaps Fishlady's alternative option might appeal to you better and be more widely available.
I'm afraid your tank is much too small for silver sharks which need an 8ft long tank and unfortunately is also too small for clown loaches which need to be in groups of six or more and in a minimum of a 6ft x2ft x 2ft tank. Depending on exactly what your pleco is, the tank is probably too small for him too as most of what's sold as a "golden" pleco grows to over a foot long.
So we can suggest fish that might be suitable, please let us know your pH and hardness (gH).
Hi. I have a 155 litre tank aquarium. The temp is 27 degrees. We had some early problems.. and lost fish.. We currently have 1 angel fish. 6 neon tetras. 2 clown loaches. 1 golden plecco . 1 tiger barb (I think?? We had 4 originally)..a massive wood shrimp and 1 remaining I am not sure!!?? I have uploaded photos to help. The tank is airated. I do a 10% water change 1 X a week , siphon the gravel 1 X ev 3 weeks. I hadn’t but am thinking I should clean the filters every month??(tell me if wrong - but when I checked after 4 weeks was filthy). I clean the filters in the water taken from the tank during water change.. Please advise on other suitable fish.. We did have 2 angels, but one died.. the surviving angel did seem aggressive to other fish but now solo does not seem to be.. Personally I would like another angel , but don’t want more trouble/deaths .. We were also looking at maybe 2/3 silver sharks - but I have read that the tank would be too small for 3 mature sharks?? (Only quoting not stating!) I would like some bright fish.. please advise and let me know your thoughts.. Thanks
