Plus one 25watt led plus one 23watt led.the 23watt was sold to me as a 28.8 watt light and I was assured that it was by seller,however I then noticed it was stamped 23w. Please can you advise me I my lighting is too little or too much. Just fell down staircase and dont want algae problems with damaged arm.many thanks.

Well your tank will tell you whats too much.

Generally speaking though for a 70gal bit deeper than usual you should (big guess) be fine for med lighting overall.
Lot depends on the quality of the t5 reflectors and efficiency of the leds amongst other things like height and placement.
Dealing with the sort of non-standard size of 39" can cause some issues like low par ends.
