Suction/Water Pressure/Leakage Issues

Greetings to all fellow pool lovers!

After replacing my cracked sand filter and replacing a flimsy old filter hose with a solid pipe, I still find myself with weak water pressure and no one around here seems competent enough to address the issue. I am fighting a losing battle with my 80 000 litre fiberglass inground pool, previously the pride of my house, which constantly turns green due to algae growth.

I am very experienced in turning green pools blue as I know all about the correct chlorine, pH and alkalinity levels and I am temporarily able to get the pool blue for a day or two yet the algae will always strike back and leave the water in a shocking state. Due to a leak, I am forced to refill the pool with tap water just so the water level is above the nozzle yet obviously that will only lower the pH level forcing me to start all over again.

I do not believe draining is necessary as the crack is near the surface and I would like to know how it might be repaired. I am still at a loss as to why I have such weak water pressure with bubbles gurgling out the nozzle as all underground pipes have been fully checked and there is no sign of a hole or leak anywhere.

At this point, I am almost ready to throw in the towel and turn my beloved pool into the area's largest fish pond and simply buy an inflatable one. Honestly, swimming in green water does not really bother me that much as I always add plenty of chlorine which should kill off the parasites and bacteria thus I believe the pool is perfectly safe. It just looks disgusting for any visitor though.

Any advice would be greatly appreciated!

Hello and welcome to TFP! :wave: So you appear to have a few issues happening at once. Let's separate each:
ALGAE: Organics in teh water are not managed via pH or TA, but 100% by proper balancing of the FC to the CYA (stabilizer) level. See our FC/CYA Chart for details. Proper testing with a TF-100 or Taylor K-2006C test kit is critical for precise testing. Fellow TFP members in your area express difficulties in obtaining a proper test kit and/or chemicals for this task. But once you get algae, you need to perform a SLAM Process.

WEAK PRESSURE: Often a result of the item above (algae). Even if you think the water is blue and good, it may not be. Excessive organics can be transparent and clog-up a filter in no time impacting water flow. A good filter pressure gauge often shows a big spike in pressure. You might also check the pump impeller to ensure nothing is tangled around that area.

FILTER LEAK: You want to fix that as well. Be sure to update your signature with all of your pool and equipment info so we can see what you have there. Maybe post a few pics as well.

CRACKED SHELL/WATER LEAK: You'll have to call around for a fiberglass repair tech in your area. A water leak can compromise the pool's foundation over time. Even if you have to contact a marine shop, they should be able to patch the shell. Even if it's not a perfect color match, a fixed leak is better.

A+B or Blue/White underwater epoxy can do wonders for a temporary underwater patch. Easy to use and readily available.
