MARINA Longstone A/Stone 6 B/Pack

Good air stone but need a strong pump to get the same amount of bubble along the all the air stone.

Fast delivery, product as described. Haven't used yet but looks good quality

Lots of bubbles in the tank. Happy fish

After washing and first installation, was working only first 2 inc of stone. Air pump is powerful, but even on maximum it was just making more bubbles, but still not in full length of stone. I managed make it work at the end, but only after I founded few lifehacks in the specific forums. Here they are, if it helps someone - first check no parts stacked inside stone tube, then put stone in boiling water, to make stone more porius, wash (stone should be wet before installing) and connect it as normal, put it inside of f-tank with conneced side first (keep not connected side up) till it reaches bottom of fish tank, then place it as normal - in horizontal position. Bubbles should be in all length of stone now.Unexpectedly to much trouble for that simple product.

ive had this air stone for around 2 weeks and it does take time for the air bubbles to go through the air stone. when i first connected it a bit would produce bubbles but after around a week the whole air stone is now producing bubbles . so my advice is give it time plus you need to soak the air stone for around a hour before using it . and make sure you use the right air pump for your tank that is key also

Great values product

These like a lot of long air stones have a tendency not to work along whole length, you can improve this two ways, first wash the stone and fill the tube with water and gently rub the stone with a stiff brush prior to installation, if you have an adjustable pump put it on full power and then reduce as liked

The media could not be loaded.  I'm very happy. I have a beautiful curtain of bubbles at the back of my tank just how I've always wanted.I did take someone else's advice from here and I boiled it first and let it dry again before I used it as its supposed to help the bubbles flow better and it certainly worked a charm. I didn't have to wait weeks or months for the bubbles, they came as soon as I started to use it.
