Right, i have been cycling for about 5 days now, i put the shrimp in and then got advice from a lfs that if the shrimps stomach explodes it can do damage to your water so i took it out yesterday. I havent tested for anything yet but i have the strip test kits and yes i have read about the saltwater tester but ive just spent £24 on 25 5 in 1 test strips and 25 ammonia test strips so im not going to buy the saltwater test kit till there all gone. When shall i test the water?
