Its a 70 litre tank Heavily planted. pics can be seen here Speedingorange.com | Just another WordPress site at first it was just a few tufts of staghorn but it is spreading. I have been plucking / wiping it off where possible and doing frequent water changes to cut down spores. I dose Tropica plant nutrition + once a week at 4ml I also seem to be getting a bit of Oedogonium? on my glass. Lighting is two juwel high light bulbs 24W 8 hours a day. C02 injected for 7 hours a day starting an hour before the lights come on. any help much appreciated!
