Hi I am sure this has been covered before, if it has please direct me to the link. I have what appears to be an oily substance floating on my water surface. Tank is very mature ( been running for 3 years ), plants growing well, very little algae, fish healthy and happy. I do weekly wc's and syphon the substrate, use Excel, flourish and occasionally some Seachem Iron. Substrate is a mix of Tetra and Flurite. Havn't had this problem before, just the last couple of days. All advise greatly appreciated The Dodger
Hi Roger its a bio film, are you adding CO2 to the tank or have you maybe changed to a different food. You can get a surface skimmer that you connect to your canister / hob that will suck it in or manually scoop it off. http://ca-en.hagen.com/File/07ef6f39-dc59-4ada-b134-4cefb26225f0
usually from too much organics in the tank. so because this is a mature tank, you are more prone to getting it. try cleaning out your filter and feeding less (that is if you are overfeeding) also, an airstone at night helps big time
Thanks for advise guys. Same food Varies between frozen blood worms and dry foods Alternate daily. Havn't setup the CO2 yet only using Excel as recommended. Will setup an airstone to run when lights go off.
Its the same as the link above Sean, sorry we having problems at work with our server! Its the grey colour of the aquaclear hobs.
The Aquaclear skimmer I have is Black. And it works wonders. My surface is always crystal clear. Just remember to adjust when feeding.
which makes a huge difference to plant health and tank health!! i find that if my plants are doing well i dont get this film. but if they not, or i just trimmed, im more prone to getting this film
low tech approach to getting rid of it... Just drag some good quality kitchen towelling over the surface like twice a week... I have noticed in tanks I dose Excell with that it does create a bit of a silvery-oiliness on the surface though
