im actually giving serious thought to just biting the bullet , getting some aquatic compost , draining the tank down putting it in , capping it with a thinner layer of sand than ive got now and then putting the plants on hold for a little while whilst i go through a period of frequent water changes etc until all settles down. after all with my previous planted tank efforts failing so badly do i REALLY feel comfortable trusting the make or break last ditch effort to a 3 inch thick layer of argos playsand ? better to do it right from the start than put the easiest option in there and rush to get planted . i get the feeling that if i wait and do it properly that both my plants and my sanity will thank me in the long run when the end result is a lush healthy tank and not another dissapoitment that means this time i forget about planted tanks for good .
