I recently decided to upgrade the 2x40w T8 tubes that came with the Roma 240 tank to 2x54w T5 tubes.
At present the plants do not seem to be growing very fast and I have most forms of algae growing in the tank (e.g. hair, fuzz, green). I am using 4 kh solution in a drop checker and this indicates a nice green colour and with the new lights the plants are now pearling like mad which they did not do under the T8's, so I do not think co2 is a problem.
I guess that nutrients are lacking in the tank and would like some help to try and determine how to remove the algae and so get the tank and plants back to looking their best.
Any help much appreciated, thanks.
