Hi all,

I'm new to planted tanks and have setup a low tech tank with a few easy to look after plants and fish. One of these plants is an Ambulia which seems to be growing well but doesn't look very nice because the tips have turned white, some with a brownish tinge.

Some info about the tank. 2ft tank with a single T8 Power-Glo close to the water surface. I also have a Juwel NovoLux LED which is currently turned off in case this was the problem. Lights are on for 9 hours solid each day. pH is stable at 6.5 due to the Fluval Stratum substrate and fortnightly 25% water changes, although the tank is quite new still. I'm not dosing any ferts, CO2, etc.

Fish bioload is reasonably low with 8 very small ember tetras (some barely more than fry!).

Any suggestion appreciated

Thanks,
John

Hi DaveKS

Thanks for the response, and apologies I've taken so long to reply. The test kit I have is the fairly basic pH, Ammonia, Nitrite and Nitrate so I haven't taken phosphate readings. The nitrate is virtually zero though which may be part of the cause.

In other news, I've started lightly dosing with Flourish and the Ambulia has greened up significantly after just one dose, so I think you hit the nail on the head!

Thanks again for your help.

John
